BMW 135i Convertible

Starting immediately the BMW 135i Coupe and the BMW 135i Convertible come with a straight-six power unit of the latest generation for the first time combining BMW TwinPower Turbo Technology, High Precision Injection and fully variable VALVETRONIC valve management, all interacting with one another to set new standards for economy with the highest level of performance.
In conjunction with the seven-speed double-clutch gearbox (DKG) featuring Sport Automatic available as an option for the first time in the BMW 1-Series as of March 2010, these superior technologies offer a further significant reduction of fuel consumption and emissions on these top-flight performers, setting up new records in acceleration and dynamic performance.
The top engine featured in both versions of the BMW 1-Series develops maximum output of 225 kW/306 hp at 5,800 rpm from a capacity of three litres, combining spontaneous and direct response with unleashed free-revving driving qualities. Peak torque of the six-cylinder is 400 Newton-metres/295 lb-ft delivered from just 1,200 rpm all the way to 5,000 rpm.
The seven-speed double-clutch gearbox with Sport Automatic shifting gears without the slightest interruption in power and torque, is likewise designed and built for dynamic performance of the highest standard.
Sport Automatic offers not just the option to shift gears manually on the electronic gear selector lever or via the shift paddles on the steering wheel, but also the usual comfort and convenience of a BMW automatic transmission.
The combination of these two innovations in a compact car naturally guarantees driving pleasure of a new standard never seen before. Accelerating from 0 - 60 mph in just 5.0 and from 0 - 100 km/h in 5.2 seconds, the BMW 135i Coupe with its double-clutch gearbox offers the same supreme standard as a thoroughbred sports car even more than in the past.
A truly unique achievement in this performance class is average fuel consumption in the EU test cycle of 8.5 litres/100 kilometres (equal to provisional combined of approx. 22 mpg US), almost one litre/100 kilometres better than the comparable figure in the former model with its six-speed automatic transmission.
This significant reduction of fuel consumption, together with acceleration to 60 mph improved once again by 0.2 seconds, clearly confirms the progress made through BMW EfficientDynamics with this new engine and transmission technology.
The BMW 135i Convertible with double-clutch gearbox accelerates to 60 mph in 5.3 seconds and reaches 100 km/h in 5.5 seconds. Average fuel consumption in the EU test cycle is 8.6 litres/100 km (provisional combined US figure approx 22 mpg), which is 0.8 litres better than on the former model with automatic transmission.
On the same fuel consumption, this is better even than the acceleration and consumption figures of the respective models with a six-speed manual gearbox: the hand-shifted version of the BMW 135i Coupe accelerates to 60 mph in 5.1, the manual-gearbox version of the BMW 135i Convertible in 5.4 seconds (0 -100 km/h on the Coupe in 5.3, on the Convertible in 5.6 seconds).
At the same time the combination of the BMW TwinPower Turbo engine with the manual gearbox also newly developed likewise enhances all-round efficiency by a significant margin. In practice, this means a reduction of average fuel consumption by the BMW 135i Coupe to 8.5 litres and a reduction on the BMW 135i Convertible to 8.6 litres/100 kilometres (provisional combined US figure for both models approx. 22 mpg).
Outstanding innovation for optimised efficiency: first-ever VALVETRONIC on a turbocharged engine.
The new straight-six power unit of the BMW 135i Coupe and the BMW 135i Convertible owes its exceptional efficiency to the first-ever combination of BMW TwinPower Turbo Technology, High Precision Injection, and VALVETRONIC valve management.
The turbocharger system following the twin-scroll principle separating the ducts for three cylinders at a time both in the exhaust gas manifold and in the turbocharger, as well as VALVETRONIC developed to an even higher standard of efficiency, contributes accordingly to the extremely spontaneous and direct response of the drivetrain.
This kind of technology allows infinite adjustment of valve stroke and valve timing on the intake valves. Throttle losses in the charge cycle are reduced to a minimum and the energy contained in the fuel is put to maximum use. In conjunction with High Precision Injection likewise optimised to an even higher standard, this offers an unparalleled balance of driving performance and fuel economy never seen before in this class.
The BMW 135i Coupe and the BMW 135i Convertible come as standard with a wide range of BMW EfficientDynamics technologies combined with one another in an appropriate symbiosis for each specific market, including features such as Brake Energy Regeneration, a gearshift point indicator on models with a manual gearbox, a map-controlled oil pump, final drive with optimised warm-up running qualities, as well as on-demand control of the engine's ancillary units such as the pressure-controlled fuel pump.
Enhanced dynamics, greater efficiency: new six-speed manual gearbox and optional seven-speed Double-Clutch Gearbox.
Both the BMW 135i Coupe and the BMW 135i Convertible come as standard with a newly developed six-speed manual gearbox. Optimised for maximum efficiency, this high-tech gearbox features dry sump lubrication significantly reducing drag forces and completely avoiding splash losses in the interest of even greater efficiency all round.
The seven-speed double-clutch gearbox with Sport Automatic featured for the first time in the BMW 1-Series makes an even greater contribution to the optimisation of driving characteristics in the spirit of BMW EfficientDynamics. The double-clutch gearbox improves both acceleration and the efficiency of these compact top-flight performers, at the same time combining this dual progress with the comfort features of a BMW automatic transmission. The seven-speed double-clutch gearbox shifts gears without the slightest interruption of power and torque and offers the driver the choice of either automatic transmission or a manual gearshift.
The fast and smooth shift of gears allows unusually harmonious acceleration and helps to reduce both fuel consumption and emissions. The close, sporting increments of the seven gears ensure that the optimum transmission ratio is always available in all situations.
A combination of dry sump and injection lubrication serves to further optimise the efficiency of the engine through a supreme level of oil supply.
Last but not least, the double-clutch gearbox is controlled with utmost convenience either through the newly designed gear selector lever or by gearshift paddles on the steering wheel.
BMW 135i Coupe and BMW 135i Convertible: outstanding performers in the compact segment and beyond.
The new six-cylinder with BMW TwinPower Turbo Technology and the seven-speed double-clutch gearbox bring out the unique character of these top performers in the compact segment even more and in greater style than ever before. Through their performance alone, the BMW 135i Coupe and the BMW 135i Convertible achieve the supreme standard of a very powerful sports car. And at the same time the driving experience conveyed by both models boasts the agility typical of a BMW 1-Series.
Superior drivetrain technology and a concept unique in this class with rear-wheel drive, the passenger cell moved far to the back, and almost ideal distribution of axle load, offer the optimum combination for unique driving pleasure.
Both models come as standard with a modified M Aerodynamics Package and M Sports Suspension. Other standard features include DSC Dynamic Stability Control with an individualised set-up, an electronically masterminded locking function on the differential, as well as model-specific control maps for Servotronic power steering and the gas pedal, again underlining the sporting character of both models.

new BMW 320d EfficientDynamics Edition

Teaming up with the BMW 320d, the new BMW 320d EfficientDynamics Edition is being presented for the first time at the 2009 Frankfurt Motor Show. This unique saloon combines fuel consumption of just 4.1 litres diesel/100 kilometres (equal to 68.9 mpg imp) and a CO2 rating of 109 grams per kilometre in the EU test cycle with engine output of 120 kW/163 hp.
The 2.0-litre four-cylinder diesel engine of this high-tech model boasts an all-aluminium crankcase, turbocharging with variable intake geometry and common-rail direct fuel injection complete with piezo-injectors. With the engine and the entire car modified once again for an even higher standard of efficiency, this unique saloon targeted above all at the German, Italian, French and Spanish markets comes with optimised aerodynamics, an extra-long final drive ratio, and an innovative two-mass flywheel incorporating a centrifugal-force pendulum.
All this makes the BMW 320d EfficientDynamics Edition the most fuel-efficient and lowest-emission car in BMW's current model range. In the fiercely contested midrange segment it is an unparalleled, highly attractive premium offer for the truly demanding and progressive customer focusing primarily on superior economy and the environment, without wishing to forego the sporting driving characteristics so typical of a genuine BMW.
The enhanced efficiency already offered by the existing models in the BMW 3-Series thanks to BMW EfficientDynamics making these cars superior to their competitors, is now raised to an even higher level in the BMW 320d EfficientDynamics Edition.
Four-cylinder diesel engine with optimised efficiency and superior performance all in one.
The BMW 320d EfficientDynamics Edition is powered by a four-cylinder diesel engine specifically optimised for even greater fuel economy and emission management and, therefore, for a standard of efficiency never seen before. All this comes from the 2.0-litre four-cylinder power unit with its all-aluminium crankcase, turbocharging and the latest generation of common-rail fuel injection featured with various power stages also in the BMW 316d, the BMW 318d and the BMW 320d. The engine specially conceived for the BMW 320d EfficientDynamics Edition develops maximum output of 120 kW/163 hp at an engine speed of 3,500-4,200 rpm and peak torque of 360 Newton-metres/265 lb-ft all the way from 1,750 to 3,000 rpm.
The engine stands out in particular through its sporting and dynamic power from low revs. The innovative centrifugal-force pendulum incorporated in the two-mass flywheel, together with the longer transmission ratio, serves to significantly reduce the level of engine speed at all road speeds relevant in practice in the BMW 320d EfficientDynamics Edition. The shift in load points beneficial to fuel economy and emissions goes together in this case with full maintenance of the spontaneity and running smoothness so typical of a BMW diesel.
Centrifugal pendulum in the two-mass flywheel for smooth and comfortable motoring without vibrations even at very low engine speeds.
To ensure smooth driving characteristics free of vibration also when driving at particularly low engine speeds, the power unit of the BMW 320d EfficientDynamics Edition features a so-called centrifugal pendulum efficiently compensating any unsmoothness in running characteristics typically encountered at low revs. This innovative component is integrated in the engine's two-mass flywheel where it dampens the vibrations generated under load, thus ensuring comfortable and acoustically optimised development of power and performance all the way from low engine speeds.
This increase in motoring comfort will encourage the driver to use a higher gear more often or, respectively, not to shift back as he otherwise would do. But when accelerating the BMW 320d EfficientDynamics Edition still offers the driving behaviour and agility so typical of BMW.
The driving dynamics characteristic of a BMW are borne out also by the car's acceleration to 100 km/h in just 8.2 seconds and by the BMW 320d EfficientDynamics Edition accelerating in fifth gear from 80-120 km/h in 9.6 seconds. Top speed is 225 km/h or 140 mph.
Lower emissions, more driving pleasure: consistently implementing the potential of BMW EfficientDynamics.
The BMW 320d EfficientDynamics Edition comes with the complete range of technologies serving to reduce both fuel consumption and emissions and already featured as standard on the other models in the BMW 3-Series. Brake Energy Regeneration, for example, serves to concentrate the generation of electric power for the on-board network on overrun and the application of the brakes, thus avoiding even the slightest increase in fuel consumption. The Auto Start Stop function, in turn, switches off the engine even during a short stop in traffic, avoiding any unnecessary consumption of fuel while idling. The gearshift point indicator on the BMW 320d EfficientDynamics Edition, to mention yet a further example, tells the driver in good time when to shift gears in the interest of optimum efficiency. And like the detachable climate compressor, EPS Electronic Power Steering operates only when needed, again in the interest of maximum efficiency.
The electric motor featured within the EPS system therefore takes up energy only when really needed for power assistance or when required by the driver. Active cooling through air flap control and tyres with reduced roll resistance also serve to enhance the car's efficiency, and the BMW 320d EfficientDynamics Edition is likewise fitted with a diesel particulates filter close to the engine. It almost goes without saying, finally, that the BMW 320d EfficientDynamics Edition fulfils the EU5 emission standard in full.
The fuel economy and emission management also featured in the other models in the BMW 3-Series are combined in the BMW 320d EfficientDynamics Edition with additional innovations, which, together with the decrease in engine power on the BMW 320d by 10 kW or 14 hp, serve to reduce fuel consumption and emissions to an even lower level, below the CO2 standard of 110 grams per kilometre relevant to taxation in many countries.
These additional features include a longer final drive ratio and the lower chassis and suspension of the car. Newly developed Aero wheel rims in turbine wheel design - the only optical sign of distinction on the car to be seen from outside - improve the level of aerodynamics to an even higher standard, giving the BMW 320d EfficientDynamics Edition a drag coefficient of just 0.26.
Within the BMW 3-Series the BMW 320d EfficientDynamics Edition is the so far most consistent implementation of the BMW EfficientDynamics development strategy, offering the motorist who really appreciates the premium character and sporting driving qualities of a BMW 3-Series and at the same time attaches utmost significance to superior economy exactly the right choice in the midrange market segment.
Comparing the efficiency of all models in this segment, BMW, introducing the BMW 320d EfficientDynamics Edition, is once again moving a step ahead of the competition. And following BMW's general policy, the improvement of efficiency offered by this innovative technology does not even require the payment of a higher price for the BMW 320d EfficientDynamics Edition, which therefore comes at the same price as the "regular" BMW 320d, which naturally is still included in BMW's model range.

BMW 5-Series ActiveHybrid Concept

The BMW 5-Series ActiveHybrid Concept offers a particularly good rendition of the new BMW 5-Series Sedan in all its dynamic, efficient and innovative qualities, at the same time representing the ongoing development of the BMW X6 ActiveHybrid and the BMW 7 ActiveHybrid with their drivetrain technology already in production.
The drive system featured in the BMW 5-Series ActiveHybrid Concept consists of a straight-six gasoline engine with TwinPower Turbo technology, eight-speed automatic transmission, and electric drive. Integration of BMW ActiveHybrid technology in a sedan already extremely efficient with its "conventional" combustion engine reduces both fuel consumption and emissions once again by more than 10 per cent. At the same time the electric motor offers a boost function, supporting the gasoline engine in generating particularly dynamic drive power for an even more sporting driving experience in the car.
Intelligent energy management likewise serves to enhance the efficiency of the overall system, its unique functions ensuring appropriate control and management of all energy paths within the car and appropriate interaction of the drivetrain components precisely adjusted to driving conditions.
The drivetrain technology featured in the BMW 5-Series ActiveHybrid Concept allows all-electric, zero-emission motoring in city traffic. At the same time a special hybrid-based Auto Start Stop function offers additional efficiency by consistently switching off the combustion engine when stopping at the traffic lights, a road junction, or in congested traffic. Optimised comfort, finally, is provided by the auxiliary climate control function already featured in the BMW 7 ActiveHybrid.
Special development of ActiveHybrid technology as part of BMW EfficientDynamics.
The concept car based on the new BMW 5-Series Sedan for the first time presents the next generation of BMW ActiveHybrid technology, a special solution exclusive to BMW for intelligent interaction of the combustion engine and electric drive focused specifically on the requirements made of a dynamic sedan in the upper midrange segment.
Taking this approach, BMW is consistently continuing the development of hybrid technology according to a modular principle (best of hybrid), thus offering the optimum rendition of BMW ActiveHybrid technology for each concept and vehicle segment.
In accordance with the BMW EfficientDynamics development strategy, this ensures highly effective and practical use of hybrid technology for the reduction of both fuel consumption and emissions.
Also in the BMW Series Sedan segment: the BMW among hybrids combines supreme dynamics with maximum efficiency.
The combustion engine is supported in the BMW 5-Series ActiveHybrid Concept by an electrical drive system developed specifically for this model and arranged in compact dimensions between the straight-six combustion engine and the automatic transmission. Drawing its energy from a high-voltage battery at the back of the car, the electric motor develops maximum output of 40 kW.
An automatic clutch connects the gasoline engine and the electric motors.
Due to the particularly high level of torque generated from the start through the electric motors, the interaction of the two drive systems ensures extremely spontaneous and dynamic acceleration whenever required.
Perfectly integrated, precisely controlled: high-voltage battery supplying power to both the electric motor and the on-board network.
In overrun and when applying the brakes, the electric drive systems acts as a generator developing electric power fed into the high-voltage battery. This converts kinetic energy otherwise wasted as heat in the brake system into electric power saved for subsequent use.
Such energy obtained without any further consumption of fuel may then be used to generate drive power or operate electrical functions in the car.
This principle is the same as that of Brake Energy Regeneration already applied in BMW's current production models, with the level of electrical energy generated by the electric motor being significantly greater and the increase in efficiency correspondingly higher.
The high-voltage battery likewise developed for this specific concept is fitted within a high-strength special case near the rear axle of the BMW 5-Series ActiveHybrid Concept. This leads to an optimum position in terms of both safety and harmonious weight distribution. An integrated control unit permanently analyses the charge status of the high-voltage battery and controls both the battery charge process by way of Brake Energy Regeneration and the system cooling process. Apart from the electric motor, the high-voltage battery also delivers electric power to the car's on-board network. Among other things, this allows efficient operation of the car's auxiliary climate control activated whenever required by a remote control function to cool down the car's interior significantly even before starting the engine.
Convenient use of the all-electric driving mode and the Auto Start Stop function is likewise guaranteed in this way, with all electrical functions such as the audio system, climate control or navigation remaining fully available even with the combustion engine switched off.
Unique: intelligent energy management with advance analysis of driving conditions.
BMW ActiveHybrid technology provides its unique potential in terms of both efficiency and driving dynamics under all kinds of conditions and throughout a wide load range.
Unlike conventional hybrid cars whose extra efficiency is largely limited to city traffic, both the BMW X6 ActiveHybrid and the BMW 7 ActiveHybrid, by combining the combustion engine and the electric motor, are able to offer significantly lower fuel consumption and emission ratings also at higher speeds. This is made possible by technically sophisticated power electronics masterminding the interaction of the combustion engine and electric motor and thus optimising the overall efficiency of the drive system as a whole.
The BMW 5-Series ActiveHybrid Concept once again raises the range of functions provided by such power electronics to an even higher standard. As an example, the energy contained in the fuel and provided by the high-voltage battery may now be used even more specifically and efficiently to provide that Sheer Driving Pleasure so typical of BMW.
Taking additional factors into account, the interaction of the two drive units in the BMW 5-Series ActiveHybrid Concept is tailored to the driver's requirements and current driving conditions with maximum precision. At the same time the power electronics also control the operation of the car's ancillary units and comfort functions, again in the interest of maximum efficiency.
The range and diversity of parameters taken into account by the system is indeed quite unique in the automobile, just as the number of functions controlled in this way. A high level of all-round networking allows the power electronics to provide intelligent energy management, thus optimising the operating strategy of the entire vehicle under all conditions.
A further unique feature of energy management in the BMW 5-Series ActiveHybrid Concept is the car's ability to adjust its operating strategy not just to current, but also to upcoming driving conditions. To do this the power electronics from the start evaluate data indicating a possible change in exterior conditions or the driver's wishes and prepare the components in the drivetrain as well as the car's electronic system for a possible change in requirements.
To analyse driving conditions up front, the system uses data provided by engine and chassis management as well as the sensors in the driver assistance systems on board the car. Data saved in the navigation system on the route chosen by the driver likewise goes into the final calculation, enabling the system to forecast driving conditions on the route directly ahead. Then, proceeding from this analysis, the car is coordinated in advance and the optimum use of all systems serves to use the energy available with maximum efficiency.
Should the system determine, for example, that the autobahn ahead is about to lead downhill, the charge level of the high-voltage battery is intelligently controlled in advance to regain brake energy upfront with maximum efficiency.
Similarly, the high-voltage battery may be fully charged in good time before the driver reaches his destination, enabling the system to switch off the combustion engine at an early point and change to all-electric drive along the final stretch of road. Indeed, this forward-looking function is able to extend the cruising range on electric power by up to 30%.
The BMW 5-Series ActiveHybrid Concept: the future of driving pleasure and efficiency in the upper midrange segment.
Optimised to an even higher standard in the BMW 5-Series ActiveHybrid Concept, the drivetrain and control systems underline the great significance of hybrid technology as a cornerstone of BMW EfficientDynamics. Looking at a new generation of hybrid technology from BMW featured in the BMW 5-Series ActiveHybrid Concept therefore offers particularly attractive perspectives, the ongoing development of BMW ActiveHybrid technology serving to provide substantial progress in all areas leading to a harmonious all-round concept with distinctive features typical of the brand.
The BMW 5-Series ActiveHybrid Concept is therefore more dynamic, efficient and more intelligent than conventional representatives of this drive technology, standing out clearly as the BMW among hybrid cars in this segment.

BMW 5-Series Gran Turismo

BMW is once again defining a brand-new segment in the automobile market. The BMW 5-Series Gran Turismo combines elegance, space, comfort and variability in truly unique style. As an attractive, future-oriented extension of the BMW 5-Series, the BMW 5-Series Gran Turismo is quite unparalleled worldwide in the upper middle segment, combining the characteristic features of a prestige saloon, a modern, highly versatile Sports Activity Vehicle, and a classic Gran Turismo in brand-new, unprecedented style.
Through its body design, the BMW 5-Series Gran Turismo combines the proportions so typical of a BMW, an elegantly stretched silhouette and a coupé-like roofline, as well as four doors with frameless windows to create one complete, harmonious unit. The front view of the car animates powerful dynamism through the sheer presence of the upright BMW kidney grille, large air intakes and dual round headlights slanted back at an attractive angle. For the first time the daytime driving light function is provided by corona rings with LED technology. Boasting clear-cut horizontal lines, the rear end comes with that characteristic look of width, power and muscle further enhanced by L-shaped rear light clusters with homogenously illuminated rows of lights in LED technology.
The luxurious and, for a car with this kind of coupé-like silhouette, surprisingly generous and variable interior gives both the driver and passengers a spontaneous feeling of comfort and well-being. This superior feeling is further enhanced by comfortable entry to the car, the slightly elevated seating position, the large window areas, the optional panorama glass roof, as well as exquisite materials and supreme quality of finish.
Flexibly adjustable, the interior of the BMW 5-Series Gran Turismo enables the driver and passengers to vary the generous space inside the car as they wish to their individual, personal requirements. In their standard position, the rear seats offer the passengers the same kind of legroom as in the BMW 7-Series combined with the same headroom as in the BMW X5. In this configuration, luggage capacity is already an ample 440 litres or 15.4 cu ft. Thanks to the partition behind the rear seats, the passenger and luggage compartments are separated acoustically and in terms of climate conditions from one another like in a saloon. When required, the rear seats may be moved individually to the front by up to 100 millimetres or almost 4", with legroom still remaining the same as in the BMW 5-Series Saloon and an increase in luggage capacity to 590 litres or 20.7 cu ft. And after folding down the rear-seat backrests together with the partition, finally, luggage space increases to its maximum capacity of 1,700 litres or 59.5 cu ft.
Offering unique functionality, the two-piece tailgate on the BMW 5-Series Gran Turismo provides exceptional variability and maximum comfort in loading the luggage compartment. Opening the small, sedan-like luggage compartment lid beneath the rear window, with the tailgate as such remaining closed, the driver and passengers are able to conveniently load the rear compartment without causing any unpleasant noise, draughts or changes in temperature within the passenger compartment. To load large and bulky objects, on the other hand, all they have to do is open the large tailgate for maximum convenience.
The sheer space and the inspiring, modern design of the interior team up to provide a truly luxurious ambience and the supreme long-distance comfort of a modern Gran Turismo. The sleek surfaces on the front and rear door panels merging smoothly into one another as well as the horizontal arrangement of the instrument panel enhance the impression of supreme generosity. Seat comfort, headroom and elbow freedom are all of the highest standard otherwise to be found only in the luxury performance class. The slightly elevated seating position, the clear, structured arrangement of the controls, BMW's new iDrive with its Control Display up to 10.2 inches in size, and the cockpit in Black Panel technology all help to give the driver maximum supremacy at all times. The rear seats may be adjusted individually fore-and-aft and also come with individual adjustment of the backrest angle. To meet the greatest demands in terms of individual luxury, finally, two individual comfort seats at the rear are available as an option.
The BMW 5-Series Gran Turismo is entering the market with a choice of no less than three ultra-modern drive units carrying over BMW EfficientDynamics into a new segment in the automobile world. The BMW 530d Gran Turismo offers a truly unique, unparalleled balance of driving experience and fuel economy with average fuel consumption in the EU test cycle of just 6.5 litres/100 kilometres, equal to 43.5 mpg imp, and a CO2 rating of 173 g/km. The two gasoline models also set new standards for efficiency in their respective engine class.
As a world-first achievement introducing a new and even more efficient range of engines, the BMW 535i Gran Turismo comes with the first straight-six gasoline engine featuring TwinPower Turbo, High Precision Injection and VALVETRONIC and developing maximum output of 225 kW/306 hp. The top engine in the range, finally, is the V8 TwinPower Turbo delivering maximum output of 300 kW/407 hp in the BMW 550i Gran Turismo. The BMW 530d Gran Turismo, in turn, comes with a 180 kW/245 hp straight-six diesel of the latest generation with an all-aluminium crankcase and common-rail direct fuel injection. All engines naturally fulfil the EU5 emission standard.
All model variants come as standard with the eight-speed automatic transmission previously to be admired only in the BMW 760Li twelve-cylinder luxury saloon. Featuring an innovative configuration of gearsets, a unique level of internal efficiency, and the same low weight and compact dimensions as a six-speed automatic transmission, this high-tech automatic combines gearshift comfort, dynamic performance, and motoring efficiency of the highest calibre.

BMW 7-Series High Security sedans

With the launch of a new generation of BMW 7-Series High Security sedans based on the BMW 7-Series, the leading supplier of premium vehicles meets the most stringent safety requirements for persons at risk while travelling in their vehicles. Both, the BMW 760Li High Security and the BMW 750Li High Security are the first models in the world to be certified to BRV 2009 and both vehicles meet the requirements of the new ballistic protection level VR7. Due to their highly effective protective armour, the non-transparent body areas of the BMW 7-Series High Security meet the requirements of the ballistic protection level VR9. Hence, both the BMW 760Li High Security and the BMW 750Li High Security provide optimum safety in the individual mobility segment in combination with unparalleled comfort of travel, superior drive technology and an abundance of innovative equipment features to guarantee confident motoring at all times.
The two BMW 7-Series High Security sedans set new standards in the protection of persons at risk while travelling in their vehicle. The unique security concept is based on findings which BMW gained as a result of its determined development work and on more than thirty years of experience in security vehicle engineering. The security concept was developed parallel to the production model and the integration of safety components is an integral part of the vehicle production process at BMW's Dingolfing plant. Specific chassis components are perfectly adapted to the increase in weight due to the sedans' armour plating. Hence, reinforced suspension, dampers and suspension strut top mountings are part of the model-specific component range. This approach ensures finely-tuned vehicle performance characteristics that cannot be achieved by retrofitted armour plating.
Reinforced vehicle-specific armour plating made from special steel as well as newly developed safety glazing protect the passenger compartment in particular from attacks of all kinds. The passenger compartment is protected by armour plating of the doors, the roof, the pillars, the front footwell and the separation wall between passenger and luggage compartments. The steel panels, which were manufactured by means of a special technique, fit the body contours perfectly. The model-specific gap sealing ensures that critical areas such as door cut and body joint lines are safely sealed.
The sedans' undercarriage is armoured by special plating which was developed with a particular focus on maximum explosion protection. Another new development is the sedans' 2.4" (6 cm) safety glazing. Due to its innovative structure, the multi-layer laminated glass cover provides a unique level of resistance. The window panes are covered with a polycarbonate layer on the inside in order to prevent shattered glass particles from penetrating the interior.
Driving dynamics and comfort on a par with production models.
Even with the highly effective security equipment, both the exclusive character of the interior as well as the driving dynamics that are typical of BMW 7-Series luxury sedans has been virtually retained. Despite their extensive safety equipment, BMW 7-Series High Security can hardly be distinguished from the corresponding production models.
The sedans' high protection level, which is second to none, is combined with a prestigious appearance, outstanding comfort of travel and an impressively powerful drive system. Both the BMW 760Li High Security's twelve-cylinder engine and the BMW 750Li High Security's V8 engine offer a combination of all-aluminium design, BMW TwinPower Turbo Technology and High Precision Injection with direct fuel injection. Both power units are distinguished by their energetic power delivery from a low number of revolutions, the running smoothness that is typical of BMW luxury sedans and their state-of-the art efficiency. Despite the increased weight of the vehicle, the engine performance characteristics of both models ensure that the new high-security sedans can achieve a dynamic acceleration from standing and a confident engine torque at all speeds. Both models have an electronically limited top speed of 210 km/h.
The newly developed V12 unit of the BMW 760Li High Security unleashes its superior power of 400 kW/544 hp at an engine speed of 5,250 rpm. Peak torque of 750 Nm comes at 1,500 rpm. In combination with the newly developed eight-speed automatic transmission, the 6.0-litre twelve-cylinder engine impresses drivers not only with its outstanding running smoothness, but also with its ability to spontaneously translate its seemingly infinite power reserve into precisely adjustable driving dynamics anytime. The BMW 760Li High Security accelerates from zero to 100 km/h in as little as 6.2 seconds.
The 4.4-litre eight-cylinder engine of the High Security is the first petrol engine of its kind with turbochargers that are located in the "V"BMW 750Li space between the cylinder banks. The V8 engine achieves 300 kW/407 hp at engine speeds of between 5,500 and 6,400 rpm. It mobilizes a maximum torque of 600 Nm that is maintained between 1,750 and 4,500 rpm. The spontaneously delivered engine thrust is applied to the rear wheels via a six-speed automatic transmission. The BMW 750Li High Security accelerates from 0 to 100 km/h in 7.9 seconds.
The BMW 7-Series High Security are distinguished by particularly harmonious driving characteristics. Both the comfort and the active security features of both models correspond to the premium quality standards that are typical of the BMW 7-Series. The innovative and in part exclusive BMW driver assistance systems ensure that potentially dangerous traffic situations can be foreseen and avoided, thus allowing for confident motoring.
The combination of a double wishbone front axle with an integral V rear axle provides numerous benefits in terms of comfort and dynamics, but above all, it results in an outstandingly harmonious handling of curves, virtually eliminating rolling, swaying or tilting behaviour. Moreover, the BMW 760Li High Security and the BMW 750Li High Security are equipped with an electronically controlled Dynamic Damping Control. The dampers adapt to the road surface as well as to the style of motoring.
The high-performance braking system ensures excellent deceleration values in all situations. Inner-vented discs and sliding calliper design for optimum efficiency on all four wheels provide extreme stability and maximum braking comfort. Run-flat tyres are equipped with temperature sensors and a separate tyre pressure monitoring system for each wheel.
Special options for individual security requirements.
Just like the range of comfort options, the security package for the BMW 7-Series High Security can be adapted to suit individual requirements. An intercom system with concealed microphones and speakers allows safe communication with people outside of the vehicle without the need to open doors or windows. Additional safety options include an assault alarm, fire extinguishing system with temperature sensor for extinguishing fires in the engine compartment and below the vehicle as well as irritant gas sensors for protecting passengers from gas attacks. If the interior protection system is triggered by excess gas levels, all windows are closed automatically, the central locking system is activated, the fresh air valves are closed and the ventilation system is shut off. An additional internal fresh-air supply system ensures that passengers are provided with breathable air.
BMW also offers special options for authorities, governments and embassies. The package provides a range of special features such as flag holders, arrangements for radio installations right through to a gun case with compartments for two machine guns in the center console. Also included is an external beacon with a roof installation system and integrated LED flashing lights for the front grille. Upon request, the vehicle may be fitted with an acoustic signalling system that can be controlled via the iDrive operating system.
In order to accommodate this exclusive circle of customers, BMW provides discreet consultancy and personalized sales and service support all over the world. BMW high-security sedans are serviced by certified special garages only. Access to the vehicles is restricted to very few selected and specially trained personnel. As part of the special customer service, BMW offers special driver training programs for security vehicles.

The new BMW 7-Series

The new BMW 7-Series already sets the benchmark in luxury performance motoring - and now BMW is moving up the standard of maximum exclusivity and supremacy in this supreme class to an even higher level, following a completely new definition: The new BMW 760i and the new BMW 760Li are taking over the top position within BMW's model portfolio, representing the highest level of motoring refinement in their segment.
The heart and foundation of this exceptional new standard comes from the twelve-cylinder power unit featured in both top models in the BMW 7-Series. Developed as a completely new engine from the ground up, the V12 is a masterpiece of modern engine technology. Superior power of 400 kW/544 hp comes at an engine speed of 5,250 rpm, with maximum torque of 750 Newton-metres (553 lb-ft) from just 1,500 rpm.
Combined with the likewise brand-new eight-speed automatic transmission, this twelve-cylinder offers not only unparalleled motoring refinement, but also supreme driving dynamics through its ability to convert seemingly unlimited power reserves spontaneously and with precise control at all times into supreme driving dynamics.
Once again, BMW's twelve-cylinder power unit is the epitome of refined performance, grand touring comfort, and stylish exclusivity. The new BMW 760i as well as the new BMW 760Li with its wheelbase extended by 14 centimetres or 5.5" for particular comfort - if not to say, luxury - at the rear, provide the clear answer to the question as to what one may expect of a genuine luxury performance saloon, with fascinating new features underscoring BMW's claim to leadership in the luxury segment.
The drivetrain with all its technical features is a masterpiece of supremacy in every respect. This applies both to the 6.0-litre all-aluminium power unit with TwinPower Turbo Technology, High Precision Injection with fuel injected directly into the combustion chambers, and to BMW's infinite double-VANOS camshaft adjustment as well as the eight-speed automatic transmission featured for the first time in a BMW.
Benefiting from all these technologies, the new BMW 760i and the BMW 760Li offer a new standard of motoring refinement, dynamic performance and all-round efficiency in a vehicle with this kind of power and output. Acceleration to 100 km/h comes in just 4.6) seconds, average fuel consumption in the EU test cycle is 12.9) litres/100 kilometres on the new BMW 760i.
In determining the cars' fuel consumption, BMW's engineers have already taken the stricter EU5 emission standard into account, meaning that with the cars' performance improving significantly fuel consumption is down by approximately 4.5 per cent versus the former model.
The new BMW 7-Series: the perfect saloon for supreme motoring refinement.
Boasting superior suspension technology, innovative driver assistance systems and luxurious comfort, as well as a combination of elegance and sporting performance borne out clearly by the car's design, the BMW 7-Series offers all the qualities required to enjoy a truly incomparable driving experience with a new twelve-cylinder power unit of a standard never seen before.
Both the new BMW 760i and the new BMW 760Li come as standard with Dynamic Damping Control including Dynamic Driving Control operated at the touch of a button on the centre console, speed-related Servotronic steering assistance, and BMW's Dynamic Drive anti-roll stability system.
In addition to these outstanding technologies, the BMW 760Li features air suspension including self-levelling on the rear axle. And as an option both models are available with Integral Active Steering offering speed-related adjustment of the steering angle on the rear wheels. With this enhanced steering function both front and rear, particularly the cars' grand touring comfort on the rear seats reaches an even higher level, above all when changing lanes at high speeds.
The supreme grand touring comfort offered by the new top-of-the-range models in the BMW 7-Series is further underlined by comfort seats, BMW's navigation system Professional, automatic air conditioning with four-zone control, cruise control complete with an automatic brake function, Park Distance Control, and Automatic Soft Close on the doors all featured as standard.
The innovative driver assistance systems available as an option include Lane Change Warning, Lane Departure Warning, Active Cruise Control with Stop-&-Go function, BMW Night Vision with detection of individual persons, the BMW Head-Up Display, a back-up camera and the Side View system. And to supplement the bi-xenon headlights as a further option, BMW offers the High-Beam Assistant and Adaptive Headlights including Bending Lights, variable light distribution and adaptive headlight range control, setting new standards for safe driving at night.
Design: discreet signals on the outside, stylish exclusivity inside.
The outstanding looks of the BMW 760i and BMW 760Li benefit from the harmonious combination of elegance, sportiness and natural presence so characteristic of the new BMW 7-Series in its design. Offering 14 centimetres or 5.5" longer wheelbase, the extended version allows particularly comfortable access to the rear seats. And thanks to the unique design of the roofline and C-pillar contours, the side view of the car, despite the extra headroom for the rear-seat passengers, maintains the same overall impression as on the "regular" saloon with its "normal" wheelbase. Both body versions, incidentally, come with the longest wheelbase in their respective segments.
Visual reference to the V12 power unit on the outside of the BMW 760i and the BMW 760Li is similarly stylish and discreet. The kidney grille for the radiator boasts an extra-wide chrome frame in slightly concave design as well as bars extending powerfully to the front. From the side, 19-inch light-alloy wheels available exclusively on these models as well as the V12 model designation on the chrome-plated gills with their integrated side direction indicators at the transition point between the front side panel and the driver's and, respectively, front passenger's door likewise serve to identify these very special models.
An additional chrome bar between the unique dual tailpipes on the exhaust system provides a special sign of distinction at the rear of both models. The exhaust tailpipes integrated in the rear air dam at the right and left, in turn, are made up of two adjacent, rectangular pipe units embellished with chrome trim and cut at a slight angle, flush to their surrounds.
Inside the BMW 760i and the BMW 760Li the luxurious ambience is supplemented by various design features tailored specifically to these two models and matched in perfect harmony, again expressing the exclusive character of the V12 models. Stainless-steel door entry trim with an illuminated V12 cover, the instrument panel finished in nappa leather and surrounded by elegant seams, the roof lining and sun visors in alcantara as well as top-quality wood trim in exclusive burr walnut with individual inlays help to give the BMW 760i and the BMW 760Li a further stylish sign of distinction versus the other models in the BMW 7-Series.
The new V12 power unit: perfection as the underlying principle, innovation as the driving power.
The twelve-cylinder power unit in a BMW 7-Series Luxury Performance Saloon guarantees a driving and travel experience quite unique in every respect. No other engine offers such an outstanding combination of power and refinement, no other power unit provides the same supreme standard of prestige.
Now these features come out even more clearly, with BMW's new V12 offering significantly more power and torque compared with their predecessors, optimising engine response and the ongoing surge of power, and further refining the engine's acoustics. The progress achieved in this way is clearly recognisable right from the start.
These features also stand out clearly from the BMW 750i which, with its modern V8 featuring TwinPower Turbo Technology and High Precision Injection, as such already offers the power and performance of a conventional twelve-cylinder.
Hence, the new V12 maintains the outstanding position of BMW's twelve-cylinder models also in the new generation of the BMW 7-Series, giving the driver of a BMW 760i and, respectively, a BMW 760Li all the assurance of absolute supremacy in the luxury class. Yet a further point is that the new engines combine the outstanding qualities of a V12 with up-to-date efficiency, offering a level of fuel economy and emission management even better than eight-cylinder models in the same segment as the BMW 7-Series.
By tradition, the twelve-cylinder enjoys a special status worldwide unmatched by other engines of different design and configuration. The twelve-cylinder represents the highest level of competence in engine technology and justifies its outstanding position through qualities only this drive concept is able to offer.
The unique status of the twelve-cylinder as an incomparably powerful and, at the same time, refined power unit is based on a construction and design principle which offers perfect conditions for supreme power and performance achieved without the slightest effort. Benefiting from an angle of 60° between the two rows of cylinders, the V12, in its supreme elimination of vibrations, comes closer to the highest standard conceivable in physics than any other engine.
All components and design features on the all-aluminium engine block are built and constructed for supreme stiffness on minimum weight. Using a closed-deck structure combined with bolts holding the cylinder head down on the floor plate of the crankcase, the engine, to mention just one example, ensures maximum stability on the cylinder liners. Double bolts on the main bearings with an additional connection to the side panels through threaded support bushes and bolts reduce the influence of lateral forces from the crankdrive on the crankcase.
Further components of the engine block serving in typical BMW twelve-cylinder style to reduce vibrations to an absolute minimum are iron-coated aluminium pistons, forged connecting rods assembled through the cracking process, as well as the crankshaft also forged for absolute perfection. This also makes the sound of the engine when idling a very special experience where the driver first has to look at the rev counter to see whether the engine is running at all.
The new V12 power unit comes with 5,972 cc maintaining exactly the same cylinder volume as on the former engine. Displacing 497.7 cubic centimetres per cylinder, the engine therefore offers exactly the right size and dimensions acknowledged by engine specialists as absolutely ideal. Bore of 89 mm/3.50" and stroke of 80 mm/3.15" provides a ratio between these two parameters of 0.9, while the compression ratio is a remarkably high 10.0 : 1 quite unusual on a turbocharged power unit.
Introduction of TwinPower Turbo Technology on the twelve-cylinder.
BMW's new twelve-cylinder comes with a number of special technical features serving to capitalise on the potential it offers through its design principle and basic structure. In particular, this includes the first-ever use on a twelve-cylinder of TwinPower Turbo Technology and High Precision Injection with gasoline injected directly into the combustion chambers.
Featuring this combination of superior technologies already to be admired on BMW's six- and eight-cylinders, responding sensitively and directly even to small movements of the gas pedal, maintaining a consistent torque curve and offering a level of fuel economy and emission management quite unusual for an engine of this calibre, the new twelve-cylinder again stands out from the competition in every respect.
Thanks to the small cylinder angle of just 60°, the two exhaust gas turbochargers developed specifically for the new V12 fit in compact arrangement on the outside of the two rows of cylinders, each supplying six cylinders with compressed air.
The turbochargers stand out in particular through their unusually good compressor and turbine efficiency - and through their particular position they provide ideal conditions for keeping the pipes between the exhaust manifold and the turbochargers short and straight for ideal flow conditions. Central supply of turbocharger air into the air collector, in turn, helps to optimise both the engine's acoustics and charge cycle. The exhaust gas manifolds identical on each row of cylinders come in each case with two three-in-one connections geared to the engine's firing sequence. In combination with the catalytic converters optimised for minimum counter-pressure, this special configuration of the exhaust gas manifolds sets the foundation for outstanding spontaneity in following the gas pedal as well as supreme power and torque coming from the twelve-cylinder.
Peak torque now increased to 750 Newton-metres or 553 lb-ft comes at just 1,500 rpm and is maintained consistently all the way to 5,000 rpm. Compared with the former engine, this means an increase in torque by 25 per cent now developed at an engine speed approximately 2,300 rpm lower.
Engine power is also built up more quickly than on the previous engine, as is borne out by the much steeper power curve leading up to maximum output of 400 kW/544 hp at just 5,250 rpm.
Intelligent solution for even more power and supremacy.
The introduction of TwinPower Turbo Technology raises the twelve-cylinder to a level of output and torque a naturally-aspirated power unit would achieve only with much larger displacement. The increase in engine size and weight inevitable in such a case, together with negative effects on the centre of gravity, fuel consumption and the agility of the car, are all avoided most efficiently and intelligently through turbocharger technology.
A further point is that TwinPower Turbo Technology gives the new V12 its unparalleled power and performance characteristics borne out in particular by the superior development of full power and torque right from the start just above idling speed and then maintained over a wide load range.
To ensure sensitive and precise dosage of power at all times, the compressed turbocharger air is cooled by a technically very demanding and elaborate indirect intercooler. This serves to minimise the overall volume of air required and shorten any delay times, again enabling the engine to respond ideally to the driver's foot on the gas pedal. An additional coolant pump feeds the separate coolant circuit required for this purpose with its air/coolant heat exchanger positioned directly on the intake unit.
The catalytic converters on the new twelve-cylinder come with the most advanced and sophisticated exhaust gas sensors and quickly reach their optimum operating temperature thanks to their special position close to the engine. Efficient treatment of exhaust gases ensures full maintenance of all international emission standards, the BMW 760i and the BMW 760Li fulfilling the EU5 emission standard in Europe and the ULEV II standard in the USA.
To reduce counter-pressure the exhaust system comes on the underfloor with largely straight pipes and manifolds increased in size to the largest possible diameter. Exhaust flaps around the silencer masterminded by the electronic control unit as a function of engine maps provide exactly the right engine sound precisely geared to current driving conditions. When idling, therefore, the V12 remains absolutely silent, not emitting any noise at all. The same applies to cruising conditions, with only very discreet sound from the engine being emitted to the outside. So it is only at higher engine speeds that the driver receives appropriate acoustic feedback on the development of power, with the engine providing its muscular V12 sound when accelerating fast and under full power. Again, this special sound effect under such dynamic conditions authentically reflects both the capacity of the engine and the intensity of power coming from within the engine compartment, characterising the dynamic qualities of BMW's twelve-cylinder.
Optimised combustion and maximum efficiency ensured by High Precision Injection.
BMW High Precision Injection is a second-generation direct injection technology serving to optimise the combustion process and use the energy contained in the fuel with maximum efficiency. Piezo-injectors positioned in the middle of the cylinder head allow particularly precise dosage of the fuel injected into the combustion chambers.
In combination with TwinPower Turbo Technology, High Precision Injection is featured in all gasoline engines in the BMW 7-Series. And now, in the new V12 power unit, this technology ensures particularly efficient and clean combustion as the starting point for a level of fuel economy and emission management quite unparalleled in this class of performance.
Opening up to the outside, the piezo-injectors are positioned in the cylinder head between the valves and, as a result, directly next to the spark plugs. They are supplied with fuel through stainless-steel pipes, fuel then being injected into the combustion chambers in finely atomised form at a pressure of up to 200 bar. This system pressure is generated by single-plunge fuel pumps on each row of cylinders and is maintained reliably at all times by short pipes and fuel travel.
The fuel injected in this process spreads out in conical form, thus burning in a particularly smooth and clean process. This, in turn, has a positive effect on engine emissions and sound, the cooling effect of the fuel/air mixture provided by direct fuel injection helping in addition to achieve a higher compression ratio than on a turbocharged engine with manifold injection. The bottom line, therefore, is an even higher degree of engine efficiency generating more power on less fuel.
In their configuration and structure, the cylinder heads largely follow the particular position of the injectors and spark plugs as well as the combustion process provided by High Precision Injection. Short combustion phases optimised for maximum efficiency build up a high level of pressure and temperature requiring optimised cylinder head geometry and an effective flow of coolant. The cylinder head components cast in a gravity process stand out in particular through their very high level of stiffness, while the cylinder head covers are made of aluminium and come with rubber profile seals.
Double-VANOS and volume flow-controlled oil pump for maximum efficiency.
Again in typical BMW style, the new twelve-cylinder comes with double-VANOS for infinite adjustment of camshaft control timing. This ensures part load running conditions with a high level of residual gas and reduced throttle loss for maximum fuel efficiency.
A further advantage of double-VANOS is its support in giving the engine a particularly direct response. Joined in a thermal process, the camshafts come with forged cams, additional triple cams on the intake side serving to drive the high-pressure fuel pumps. The valves on the exhaust side, in turn, are filled with sodium for optimum cooling and come with chrome-plated shafts.
The supply of oil to the new twelve-cylinder has also been optimised, the volume flow-controlled oil pump operating on individual demand with maximum efficiency: The six-chamber pendulum-slide pump delivers only as much oil as the engine requires at any given point in time under specific driving conditions.
An oil level sensor is integrated in the oil sump made of pressure-cast aluminium. And instead of a manual oil dipstick, an oil level indicator in the instrument cluster also operating while driving informs the driver of the oil level whenever required.
The new twelve-cylinder models in the BMW 7-Series again feature a wide range of technologies for minimum fuel consumption and emissions based on BMW's strategy of EfficientDynamics. These include Brake Energy Regeneration, electric coolant pumps operating on demand, and the volume flow-controlled oil pump further optimising the balance of load performance and fuel consumption.
With an increase in engine output versus the former models by 22 and an increase in maximum torque by 25 per cent, the average fuel consumption determined in the EU test cycle has been reduced to 12.9) litres/100 kilometres. The emission rating of the BMW 760i is 299) grams per kilometre.
The engine coolant system on the new twelve-cylinder excels through consistent integration of all pipes in the crankcase, optimised cross-sections and the surface structure ensuring a maximum heat exchanger function helping to warm up the engine far more quickly than before on the former power unit.
The arrangement of the coolant inlet immediately next to the main inlet duct for supplying oil serves in addition to connect the two media in thermal terms, again helping to warm up engine oil and maintain the ideal temperature at all times.
The flow of coolant is separated on the two rows of cylinders, in each case running diagonally from the rear outside to the front inside. And last but not least, the arrangement of the outlets again helps to consistently spread out and maintain the temperature level over a wide range of engine speed.
BMW's outstanding competence in twelve-cylinder technology: a long tradition of supreme performance.
This is the fourth time that a twelve-cylinder power unit marks the top end of the engine portfolio featured in the BMW 7-Series. And indeed, every new generation has further reinforced BMW's position as the leading manufacturer of luxury performance saloons. A BMW 7-Series with a twelve-cylinder power unit stands for exclusivity, supremacy and, not least, genuine innovation, the top-of-the-range engines providing the highest standard also on account of the maximum demands they are expected to meet right from the start in the development process.
BMW's outstanding competence in the development and production of twelve-cylinder power units is based on a long tradition extending all the way back to the year 1925 when the Company for the first time hit the headlines by building an aircraft engine with twelve cylinders. Back then BMW's V12 developed maximum output of 750 hp, with two BMW twelve-cylinders powering the Dornier Wal seaplane just five years later in its record flight across the Atlantic.
In the second half of the 20th century BMW became the pioneer in introducing the twelve-cylinder in the most outstanding luxury cars. The BMW 750i launched in 1987, for example, was the first German twelve-cylinder saloon after the war. In the years to follow a long story of success in motorsport likewise contributed to the exceptional reputation of BMW's twelve-cylinders. The BMW V12 LMR, for example, dominated the racing scene right from the start in its very first race in 1999, the 12 Hours of Sebring, and in the same season clinched overall victory in the 24 Hours of Le Mans.
World debut: eight-speed automatic transmission in the new BMW 760i and the new BMW 760Li.
The unique qualities of the new V12 power unit with TwinPower Turbo Technology and High Precision Injection are combined in the new BMW 760i and the new BMW 760Li with an equally innovative concept for the transmission of power: the newly developed eight-speed automatic transmission making its world debut in a BMW production car. Ideally tailored to the power and performance characteristics of the twelve-cylinder power unit, the eight-speed automatic transmission combines supreme gearshift comfort, sportiness and efficiency at a level never achieved before.
The new eight-speed automatic transmission excels through the innovative configuration of gears and gearsets allowing the use of additional gears and a larger range of gear increments than on the former six-speed automatic transmission, without any negative effects on the size of the transmission, its weight, and the inner efficiency of the system.
The eight forward gears and the reverse gear all incorporate four simple gearsets and five gearshift elements. The innovative arrangement of these components seen for the first time on an eight-speed automatic transmission ensures that only two clutches are open in each gear at any given point in time, significantly reducing frictional losses under all driving conditions to an absolute minimum.
Over and above the wider range of gear increments and the high degree of internal efficiency, this is a further factor contributing to the outstanding overall efficiency of the new transmission system. So again, the intelligent concept of this new eight-speed automatic transmission harmonises perfectly with the BMW EfficientDynamics development strategy.
Introduction of the first eight-speed automatic transmission in the BMW 760i and the BMW 760Li marks the starting point to a generation change in the area of power transmission systems. The six-speed automatic transmissions currently featured in all BMW model series already set the standard in terms of shift comfort, reaction time, gearshift speed, and efficiency and, through their compact design and configuration as well as their universal use in various vehicle segments and power classes, already offer unparalleled all-round qualities. The first and foremost objective in developing the new generation of automatic transmissions, therefore, was to retain all the design features of the six-speed automatic transmission and add new potentials in terms of motoring comfort, performance and efficiency.
Optimum gearset configuration as the result of scientific research.
To achieve significant progress over BMW's proven six-speed automatic transmissions, BMW's engineers right from the start initiated an in-depth development process providing the basis for the new transmission. The initial consideration was that particularly the improvement of efficiency as desired was only possible with a transmission system offering an even larger number of gears and a wider range of gear increments versus a six-speed automatic transmission. A further objective was to keep the number of additional components to a minimum in order to optimise the inner efficiency of the system.
Apart from BMW itself, a number of specialised partners in development such as ZF Friedrichshafen AG participated in the search for an optimum concept fulfilling all these requirements. Working together closely, the complete team developed analytical methods serving to establish and balance the pros and cons of all theoretically conceivable variants of a planetary gear system. To begin with, both the number of gears was open as was the structure of the new transmission system with its underlying concept. The fundamental objectives, therefore, were to achieve the highest conceivable standard of efficiency and to keep the new transmission compact and light.
Studies jointly conducted by engineers and scientists eventually led to a solution offering the best balance of internal efficiency and overall running qualities: the new eight-speed automatic transmission with two additional gears and a gear increment range increased from six to seven gear units, with the number of gearsets being increased by only one to a total of four and the number of clutches remaining unchanged.
Triple progress with two additional gears: gearshift dynamics improved, comfort optimised, efficiency maximised.
Thanks to the larger range of gear increments now offered by the new transmission, the driver is able to use the highest gear at significantly reduced engine speed far more often than before. In the BMW 760i and the BMW 760Li, this not only optimises the car's economy also at higher speeds, but also enhances the smoothness and refinement of the twelve-cylinder.
With the number of gears being increased to eight, the individual steps between gears are smaller than before, despite the overall range of gear increments. Clearly, this benefits the sporting character of the transmission and, as a result, the dynamic nature of the car again in typical BMW style.
While accelerating the harmonious balance of gear ratios provides a very smooth and consistent increase in road speed, a feature corresponding ideally with the ongoing surge of power from the new V12 and again confirming the unparalleled supremacy of the BMW 760i and the BMW 760Li.
A further advantage of the small gear increments is the enhancement of gearshift comfort in BMW's most outstanding Luxury Performance Saloon, with only a slight change in engine speed when shifting from one gear to another.
The reaction and gearshift times even shorter than with the former six-speed automatic transmission benefit both motoring comfort and driving dynamics, with only one clutch having to be disengaged when shifting up or down either one or two gears. At the same time direct gear detection enables the driver to shift up or down by more than two gears, again with extremely short reaction and gearshift times. And last but not least, the downshift from eighth to second gear particularly important for spontaneous acceleration also takes place as a direct gear change requiring the system to open only one clutch.
This particular configuration is of great significance for supreme driving pleasure in the BMW 760i and the BMW 760Li, enabling the driver to use the higher gears for perfect efficiency and motoring refinement particularly often while enjoying the car's maximum performance spontaneously at all times.
Flexible, up-to-date, oriented to the future.
With the number of transmission components being increased only slightly over the former six-speed automatic transmission, the new eight-speed automatic offers an unusually high level of internal efficiency. So-called gear-mesh efficiency, for example, is more than 98 per cent in each gear. And being configured as a direct gear, sixth gear reduces frictional losses to zero.
The low weight of the new transmission virtually identical to that of the former six-speed automatic likewise benefits the overall efficiency of the car, with the integration of an additional gearset being compensated by the optimisation of weight in other areas.
In all the minimum converter slip, the high degree of internal efficiency, low frictional losses with only two clutches open at a time, the longer transmission ratios on the higher gears and the transmission management giving preference to low engine speeds at all times offer a reduction of fuel consumption versus the former six-speed automatic by approximately 6 per cent.
As a result of these improvements and highlights in technology, the new eight-speed automatic transmission is not only the optimum system currently available, but also a future-oriented solution for the transmission of power in a premium car.
The new transmission may be combined with all kinds of engines and levels of performance, and may be integrated not only in cars with rear-wheel drive, but also in all-wheel-drive models. At the same time the eight-speed automatic transmission may be combined with hybrid drive, making it part of BMW's Active Hybrid technology combining an eight-cylinder gasoline engine with an electric motor. This innovative drive concept will be reaching production standard in the first hybrid model in the BMW 7-Series in the course of 2009.
Setting the new standard in motoring supremacy: the new BMW 7-Series with twelve-cylinder power unit and eight-speed automatic transmission.
Twelve cylinders and eight speeds - this combination re-defines the most supreme standard of exclusivity and refinement in the luxury class. The drive technology featured in the new BMW 760i and the new BMW 760Li makes a significant contribution to the significant innovation of power technology ensured by the BMW brand, the unique power and performance characteristics of the new V12 power unit and the innovative concept of eight-speed automatic transmission joining forces to provide a truly fascinating driving experience.
Superior power is thus converted into equally superior driving dynamics with an exceptionally high standard of motoring refinement. Offering supreme smoothness and full availability of enormous power reserves at all times, the twelve-cylinder simply begs the driver and passengers to enjoy a most comfortable driving experience wherever they go, experiencing sporting performance of the highest calibre as an unparalleled asset in luxury performance motoring.
The eight-speed automatic transmission perfectly supplements both the supremacy and the dynamic character of the power unit. At the same time the exceptional efficiency of both top models in the BMW 7-Series results not just from the V12 power unit, but also from the transmission. Innovations developed in the context of BMW EfficientDynamics allow this luxury saloon to combine acceleration to 100 km/h in 4.6) seconds with average fuel consumption in the EU test cycle of 12.9) litres/100 kilometres.
The outstanding position of the new BMW 760i and the new BMW 760Li is further underlined by suspension technology specially developed for this Luxury Saloon, combining innovative driver assistance systems partly exclusive to BMW with a wide range of comfort amenities all featured as standard. More than ever before, therefore, both models meet the demands and requirements of the most discerning motorist seeking individual mobility of the highest calibre as part of his or her lifestyle dedicated to absolute perfection.

BMW 7 ActiveHybrid

On the heels of the BMW X6 ActiveHybrid, BMW announced the production version of the all-new BMW 7 ActiveHybrid, which will also premiere at the 2009 Frankfurt Auto Show (IAA). The BMW 7 ActiveHybrid will reach America shores in Spring, 2010. Based on the newest BMW 7-Series, this unique car sets new standards for performance and efficiency in the premium luxury class.
This symbiosis of an upgraded twin-turbo, High Precision Direct Injection, V8 engine with a 3-phase synchronous elec¬tric motor gives the BMW 7 ActiveHybrid a combined output of 455 hp and maximum torque of 516 lb-ft (preliminary figures). Power is transmitted via an 8-speed automatic transmission with the electric motor positioned between the engine and the torque converter. The electric motor receives its supply of energy from a lithium-ion battery developed specifically for use in this automobile.
Precisely controlled interaction of both power sources serves to maximize the efficiency and dynamic performance of the BMW 7 ActiveHybrid. The result is a unique driving experience that demonstrates the performance capabilities of modern hybrid technology. The BMW 7 ActiveHybrid accelerates to 60 mph in 4.8 seconds (preliminary), while delivering fuel economy approximately 15% better than the 750i. Official EPA ratings will be available closer to the US market launch.
BMW ActiveHybrid technology also provides new features that promote efficiency while preserving comfort. As an example, the BMW 7 ActiveHybrid is the first BMW with automatic transmission to feature Auto Start Stop to maximize efficiency by avoiding engine idling when stopped. Another advantage is that the air conditioning and ventilation system remains fully operational when using Auto Start Stop. In this case, power is supplied directly through the 120-volt on-board network powered by the lithium-ion battery.
Special displays in the instrument cluster and the Central Display inform the passengers of the degree of efficiency and the current operating status of the hybrid components. The ActiveHybrid 7 is distinguished from the 750i by aerodynamically-tuned ten-spoke 19-inch light-alloy Aero wheels, and model designations on the trunk lid, C-pillars, and on the door cutouts. The BMW 7 ActiveHybrid is also available in Bluewater Metallic exterior paintwork.
Like existing BMW 7-Series models, BMW's first luxury sedan with ActiveHybrid technology will enter the market in two body variants. The extended version of BMW 7 ActiveHybrid has a wheelbase increased by 5.5", all of which is devoted to the enhanced comfort of rear-seat passengers. Both models are available with a wide range of options from the portfolio of equipment and accessories offered on the BMW 7-Series, enabling the tailoring of the ActiveHybrid 7 to individual tastes and requirements.
BMW ActiveHybrid: A key element of the BMW EfficientDynamics philosophy.
The BMW 7 ActiveHybrid takes an innovative approach to ensure outstanding efficiency in this segment. At the same time this unique sport sedan offers dynamic driving characteristics at a level that one would expect from The Ultimate Driving Machine. BMW ActiveHybrid is an important element within the BMW EfficientDynamics philosophy meant to offer technologies able to significantly reduce fuel consumption and emissions on every new model while enhancing driving performance.
BMW uses hybrid technology because it can make an effective contribution to the reduction of fuel consumption and emissions. As a rule, the savings potential of hybrid technology increases with the power of the combustion engine interacting with the system. In the case of the BMW 7 ActiveHybrid precise coordination of the electric motor and the V8 serves to optimize the efficiency of the combustion engine under all operating conditions.
Intelligent energy management for generation, storage and use of electric power.
The ActiveHybrid concept stores energy in a compact, high-performance lithium-ion battery. The processes of charging the battery, supplying power to the electric motor, and electric ancillaries are managed by a control unit developed specifi¬cally for the BMW 7 ActiveHybrid.
Energy Regeneration: Electric power captured using no extra fuel.
BMW ActiveHybrid technology uses energy that would be normally converted into heat through the brakes, and therefore wasted in conventional cars. The BMW 7 ActiveHybrid features an enhanced version of Brake Energy Regeneration already used in some current BMW models running on a combustion engine alone. In this case the integrated electric motor acts as a generator when coasting or applying the brakes, in order to feed electric power into the battery. Brake Energy Regeneration converts some of the vehicle's kinetic energy into electric power for the on-board network whenever the driver lifts off the accelerator or applies the brakes. On acceleration, electricity is fed back into the on-board network from the lithium-ion battery. This sequence relieves the combustion engine from the task of converting some of its fuel energy into electric current, and thus enables the engine to provide more power directly to the rear wheels. The result is better acceleration even than the 750i, despite the fact that the additional power is obtained in a way that does not require additional consumption of fuel.
When the driver requires only a small amount of brake force, the system uses only the drag of the electric generator (motor). The mechanical brakes are activated only when the driver presses down the brake pedal harder for more stopping power. Dynamic Stability Control controls the balance of electrical and mechanical braking so adeptly that the driver does not even perceive the transition from braking with electric power to braking with the mechanical brake system.
Two interconnected on-board networks for flexible management of energy.
The BMW 7 ActiveHybrid features both a conventional 12-volt on-board network fed by an absorbent glass mat (AGM) battery and an additional battery featuring lithium-ion technology operating at 120-volts. The lithium-ion battery supplies power to the electric motor as required and serves to start the engine. Electric power generated by Brake Energy Regeneration is fed into both on-board networks. The air conditioner compressor on BMW 7 ActiveHybrid is integrated in the 120-volt network. All other electrically operated functions of the car are supplied by the 12-volt network. The two on-board networks are connected by a voltage converter featuring flexible energy management. Both batteries are charged and maintained through Brake Energy Regeneration. The 12-volt battery is fed with energy from the high-voltage network.
Cutting-edge battery technology: lithium-ion with superior capacity and multi-cycle operating strength.
BMW found that lithium-ion battery technology offers sufficient energy storage capability while taking up minimal space. The result is that the BMW 7 ActiveHybrid gives up almost no luggage capacity to its conventional siblings (750i and 750Li), because the 120-volt battery is small enough to be mounted underneath the trunk floor. Furthermore, the weight penalty incurred by this battery is minimal, meaning less energy is consumed to carry it. Using this technology enables the ActiveHybrid 7 to maximize storage capacity and acceleration in the hybrid luxury sedan segment. It is the fastest-accelerating hybrid sedan in the world.
The useful energy provided by this high-performance battery is 400 watt-hours. The battery itself is comprised of 35 cells and an integrated control unit which continuously analyzes the charge level and ensures appropriate dependability under all conditions. Despite its high level of performance, the lithium-ion battery measures just 14.6 x 8.7 x 9.1 inches (37 x 22 x 23 centimeters) and weighs a mere 59.5 lb or 27 kg.
Hence, it is only slightly larger than a conventional car battery and is housed conveniently in the trunk floor between the wheel arches of BMW 7 ActiveHybrid, safely surrounded by a high-strength special casing. This location provides protection for the battery and helps to preserve the 7-Series' ideal 50-50 weight distribution. The luggage compartment with its capacity of approximately 13 cu. ft. offers adequate space for four 46-inch golf bags.
Twin-turbocharged V8 gasoline engine with High Precision Direct Injection.
The combustion engine is the innovative reverse-flow V8 introduced in the BMW X6. The world's first V8 gasoline engine with two turbochargers in the V-section between the two rows of cylinders develops power throughout the entire engine speed range. The spontaneous and direct response of this engine results from its compact configuration, which allows the shortest exhaust manifolds.
Displacing 4.4 liters, this outstanding engine delivers its maximum output of 440 hp between 5,500 and 6,000 rpm. Peak torque of 475 lb-ft is maintained from 2,000 to 4,500 rpm, with High Precision Direct Injection ensuring precise supply of fuel at all times. Piezo-injectors positioned in the combustion chambers between the valves ensure a smooth, efficient and clean combustion process. The engine fulfils the European EU5 standard as well as the ULEV II standards in the US.
Compared with the engine featured in the BMW 750i/Li, this version has been modified in numerous respects to the specific requirements of the BMW 7 ActiveHybrid. There is no starter, alternator, or belt drive for the air-conditioning compressor and hydraulic pump. The cooling system has been modified for hybrid operation. The result is remarkable power from idle. The response of the engine is enhanced by the electric motor with its additional torque. The direct response to the accelerator pedal is impressive when compared either with conventional 7-Series models or existing hybrid vehicles already in the market. Acceleration to 60 mph in 4.8 seconds (preliminary) ranks it among the fastest and most thoroughbred sports cars in the world. Top speed of BMW 7 ActiveHybrid is electronically limited to 150 mph.
Electric motor starting and supporting one of the most advanced V8s.
The three-phase synchronous electric motor featured in BMW 7 ActiveHybrid is positioned between the engine and the torque converter, and is connected to the crankshaft. Shaped like a disc, the electric motor weighs 50.7 lb (23 kg). Its compact design ensures full integration in the transmission housing.
The electric motor generates boost of approximately 20 hp and peak torque of 155 lb-ft. When operating as a generator in Brake Energy Regeneration, the electric motor produces approximately 27 hp of brake force.
In total, the BMW 7 ActiveHybrid features a maximum system output of 455 hp and peak torque of 516 lb-ft (preliminary). Normally, this level of power output would require a correspondingly high increase in fuel consumption. The BMW 7 ActiveHybrid, in contrast, combines its power with an equally impressive increase in fuel efficiency of about 15%.
8-speed automatic transmission in combination with Auto Start Stop.
To transmit the drive power developed jointly by the V8 and the electric motor, the BMW 7 ActiveHybrid features a newly developed 8-speed automatic transmission specifically tailored to the demands of hybrid technology. This high-tech transmission combines shift comfort, sportiness and efficiency at unprecedented levels.
The new 8-speed close-ratio automatic transmission uses an inno¬vative gear-set configuration providing two additional gears and a larger overall gear range than the 6-speed automatic transmission used by BMW without negative effects on size, weight, or internal efficiency. With the new transmission, the V8 engine is better able to stay in the power peak while ensuring greater overall efficiency.
Overall efficiency is further enhanced with the Auto Start Stop function. Auto Start Stop automatically switches off the combustion engine at idle, eliminating fuel consumption when stopped. Once the driver's foot comes off the brake pedal, the engine restarts instantaneously.
Starting of the V8 engine is accomplished by the electric motor, which is supplied with power from the high-voltage battery. This enables the engine to start extremely quickly and without any vibration. The automatic transmission is maintained in a "ready-to-drive" mode by a new hydraulic pressure accumulator for the valve body of the transmission. Additionally, the engine control unit "remembers" engine crank position and uses delay-free ignition to restart the engine in less than one crank rotation. The engine is also switched off when the driver uses the Auto Hold function. The driver just has to slightly press down on the gas pedal in order to reactivate the engine.
Continuous climate control in all circumstances.
The climate control system in the BMW 7 ActiveHybrid is supplied with power directly from the high-voltage battery, thus ensuring all the usual functionality regardless of whether the engine is running.
Hence, operation of Auto Start Stop does not compromise the infotainment or climate system operation. The desired interior temperatures are maintained consistently, regardless of how frequently or for how long the engine shuts off.
The standard 4-zone automatic climate control has a parked-vehicle function activated whenever desired by remote control. This feature serves to cool down the interior in hot weather before getting into in the car. The highly efficient air conditioning system can reduce in interior tem¬perature quickly and efficiently by more than 50 degrees Fahrenheit, providing pleasant starting conditions in an appropriately cool and pleasant passenger compartment. By running on pure electric power, the air conditioner compressor begins cooling the car more quickly than in a conventional system.
Efficiency made visible: special display concept.
Featuring Black Panel technology, the instrument cluster in the BMW 7 ActiveHybrid is supplemented by an energy flow display in the lower section of the tachometer, a blue arrow shows the current status of Brake Energy Regeneration. When accelerating, an additional graphic display illustrates the boost effect generated by the electric motor.
Using the iDrive control system in the Central Display, the driver is able to see a detailed view of the interaction between the V8 engine and electric motor. Beyond the current charge level of the lithium-ion battery, this display also shows the real-time flow of energy. As an alternative to this graphic display, the system can analyze the current efficiency. In this case a bar graph, which is updated every minute, shows the efficiency levels achieved by the hybrid components during the last fifteen minutes.
Cutting-edge suspension technology for maximum control and comfort.
When the new BMW 7-Series was introduced in 2009, it set new standards for comfort and driving dynamics. The double-wishbone front suspension and an enhanced Integral-V rear suspension provide the ActiveHybrid 7 with the ride comfort one would expect of a BMW sport-luxury sedan with the handling and control of a sports car.
The long-wheelbase version of BMW 7 ActiveHybrid includes self-leveling rear suspension. Both models are fitted with BMW's vehicle speed-variable Servotronic power steering as well as Driving Dynamics Control. The driver is able to choose the preferred shock absorber setting, the appropriate operation of Dynamic Stability Control, the shift character of the automatic transmission, as well as the throttle response and Servotronic steering assist.
The brake system on the BMW 7 ActiveHybrid provides excellent stopping power in every situation. Inner-vented discs and floating calipers front and rear guarantee resistance to fade. The ActiveHybrid 7 comes standard with 19-inch light-alloy rims in an aerodynamically optimized ten-spoke Aero turbine wheel design, unique to this model. Likewise, runflat tires measuring 245/45 R19 front and 275/40 R19 rear enable the driver to continue even after a complete loss of pressure at a speed of up to 50 mph for up to 150 miles. As an added measure of security, the Tire Pressure Monitor will warn the driver if ever the pressure in any of the tires drops more than 20 percent.
ActiveHybrid safety systems.
The safety concept for the car's hybrid components is comprehensive. All components in the high-voltage system feature full insulation and special plug connectors. The lithium-ion battery is protected by a high-strength steel housing and is positioned between the wheel wells in the luggage compartment, and has already been subjected to a wide range of crash tests. Last but not least, the entire high-voltage system is automatically switched off within a fraction of a second in case of a malfunction or collision.
Best of Hybrid: flexible development for optimized concepts on each model.
The hybrid components featured in BMW 7 ActiveHybrid were developed jointly by BMW and Daimler in a cooperation project seeking to develop and test components for hybrid drive in luxury performance cars. Apart from the electric motor and the lithium-ion battery, this joint venture also served to develop the power electronics for the high-voltage network featured in the BMW 7 ActiveHybrid.
Each manufacturer subsequently integrated the hybrid components into the respective model in accordance with individual, brand-specific requirements. One of the unique characteristics of the BMW 7 ActiveHybrid is exemplified by the combination of an electric motor with a V8 engine.
BMW ActiveHybrid is based on a modular principle which, following the Best of Hybrid strategy, ensures perfect integration of the optimum component in vari¬ous vehicle concepts. Hence, the mild hybrid concept of the BMW 7 ActiveHybrid is tailored ideally to the specific requirements of this model as is the full hybrid concept for BMW X6 ActiveHybrid, which will arrive at BMW Centers in late 2009.
