World debut of the BMW Concept 7 Series ActiveHybrid for the first time offering the potential of BMW ActiveHybrid technology in the luxury saloon segment as part of the BMW EfficientDynamics innovation strategy. In typical BMW style, this new Concept Car combines a significant reduction of fuel consumption and emissions with a standard of driving dynamics never seen before even in this class of hybrid cars. • The BMW Concept 7 Series ActiveHybrid comes with an intelligent symbiosis of the V8 cylinder petrol engine and electric drive as a mild hybrid concept. The drivetrain technology featured in the Concept Car allows enhanced driving dynamics together with a reduction of fuel consumption and emissions by 15 per cent in the EU test cycle versus the same car running on a combustion engine only. And at the same time the use of BMW ActiveHybrid technology does not require any concessions in terms of everyday driving qualities and the specific features of the BMW 7 Series. The Concept Car offers the ideal synthesis of motoring comfort, visual presence and supremacy of the BMW 7 Series, on the one hand, combined with future-oriented, high-efficiency BMW ActiveHybrid technology, on the other. This provides the option to enrich the sheer driving pleasure so typical of the BMW brand by the additional highlights and fortes of BMW ActiveHybrid. Implementation of such technologies in a luxury performance saloon of this caliber leads to a new perception of hybrid technology as such: In the configuration developed by BMW hybrid technology ensures a significant increase in efficiency without in any way giving up the high standard of driving dynamics, motoring safety and comfort so typical of the brand. Technical highlights: • The drivetrain of the BMW Concept 7 Series ActiveHybrid is made up of a V8 gasoline engine with Twin Turbo and High Precision Injection based on the power unit of the BMW 750i. Maximum output of the conventional engine in the regular production model is 300 kW/407 hp, with peak torque of 600 Newton-meters or 442 lb-ft. Now this superior engine is combined with an electric motor fully integrated in the transmission housing, developing maximum output of 15 kW/20 hp and peak torque of 210 Newton-metres/155 lb-ft. So with the mild hybrid concept, the electric motor boosts the dynamic driving potential of the eight-cylinder gasoline engine in a unique manner most appropriate for the character of the BMW 7 Series, giving the car even more dynamic acceleration. • Using Brake Energy Regeneration, the electric motor supplies electric power to the power-consuming items on board the car, minimising the direct conversion of fuel into electrical energy and maximising the drive power available for enhanced driving dynamics. • T he V8 power unit offers ideal features for a concept focusing on both driving dynamics and efficiency all in one. It is the only eight-cylinder gasoline engine in the world with its turbochargers arranged conveniently in the V-space between the two rows of cylinders, and at the same time it is the most efficient engine in its class. • The hybrid components developed for the Concept Car are based on technology created by BMW and Daimler in their cooperation on hybrid drive systems. In this joint venture the two manufacturers have successfully developed components for hybrid drive including the power electronics and high-voltage batteries. Naturally, the hybrid drive system featured by BMW offers all the characteristics and highlights typical of the brand. • BMW ActiveHybrid is based on a modular concept following the “Best of Hybrid“ strategy and in each case integrating the best components for different vehicle segments. The components featured in the BMW Concept 7 Series ActiveHybrid – the mild hybrid transmission and the eight-cylinder petrol engine – supplement each other in the same ideal manner as the full hybrid transmission and the eight-cylinder petrol engine in the BMW Concept X6 ActiveHybrid. • The compact electric motor integrated in the transmission housing replaces the conventional alternator driven by the engine as well as the starter. Electrical energy is generated through Brake Energy Regeneration with a unique degree of efficiency and without in any way impairing the drive power of the engine itself. Integrated power electronics, in turn, ensure compact design within dimensions never seen before, as well as safe and secure arrangement of all hybrid components. A high-performance lithium-ion battery integrated in the luggage compartment in accordance with the package of the car saves the energy generated and supplies power to the on-board network. Through its high storage capacity, the battery makes full use of Brake Energy Regeneration with its particular potential. • Thanks to the higher degree of electric power provided in this way, additional functions in the car are run completely under the electric power supply. The Auto Start Stop function preventing the combustion engine from running in the idle mode is particularly helpful and comfort-oriented in this case thanks to the combination with ActiveHybrid technology. Exterior design: • T he BMW Concept 7 Series ActiveHybrid demonstrates the integration of BMW ActiveHybrid technology in the BMW 7 Series luxury saloon. All hybrid components are fitted and arranged according to the car’s specific package. The electric motor and the power electronics are integrated in the transmission housing, where they cannot even be seen from outside. A specially designed trough in the luggage compartment made of aluminum accommodates the compact lithium-ion battery. • The front end of the BMW Concept 7 Series ActiveHybrid boasts the natural presence so typical of the 7 Series, enhanced in particular by the large, upright BMW kidney grille. A specific feature of the Concept Car is the aluminum band stretching across the entire width of the front end beneath the numberplate and serving to provide a controlled flow of air in the interest of optimum aerodynamics. • T he lower air intake scoop is covered in the middle by this aluminum band, the openings to the left and right reflecting the contours of the headlights just above and split horizontally by the aluminum band tapering out towards the sides. • The foglamps fitted at the extreme edge of the air intake openings are made up in each case of seven LED light units. • Seen from the side, the BMW Concept 7 Series ActiveHybrid is further enhanced in its sporting and elegant look by 20-inch light-alloy rims in V-spoke design. The rims are finished in body color, the Blue Water Metallic paintwork on the car and rims serving as a particular sign of distinction for BMW’s maximum-efficiency Concept Cars. At the rear of the BMW Concept 7 Series ActiveHybrid an additional air guidance element made of aluminum and exhaust tailpipes with new contours symbolise and round off the innovative drive concept. As an analogy to the front end of the car, the aluminum band integrated in the rear apron stretches across the entire width of the vehicle, at the same time forming the upper surround on the exhaust tailpipes both positioned far to the outside. The unusually wide and fl at contours of the tailpipes, finally, form an almost multiple-plate structure thanks to the additional horizontal crossbar. Maximum efficiency in the luxury class, supreme dynamics in the hybrid segment – precisely these are the unique standards offered and combined with one another by the BMW Concept 7 Series ActiveHybrid. Introducing this Concept Car based on the new BMW 7 Series, BMW is clearly demonstrating the potential offered by the most advanced hybrid technology available today. The BMW Concept 7 Series ActiveHybrid comes with hybrid components tailored precisely to the character of this unique saloon, offering driving comfort, everyday motoring qualities and driving safety of the supreme standard only the BMW 7 Series is able to provide. In addition, the BMW ActiveHybrid technology featured in the Concept Car reduces both fuel consumption and emissions by 15 per cent versus the same car with a combustion engine and offers a standard of driving dynamics clearly exceeding all series models with hybrid technology presented so far. The BMW Concept 7 Series ActiveHybrid combines an eight-cylinder gasoline engine and an electric motor developing 15 kW/20 hp and maximum torque of 210 Newton-metres/155 lb-ft as a mild hybrid concept. Electric power is generated by a particularly powerful variant of Brake Energy Regeneration already featured in the BMW Group’s regular production cars. The energy generated in this way is then stored in a lithium-ion battery fitted in accordance with the package of the car beneath the luggage compartment. This electrical energy serves to supply the on-board network and, in addition, to boost the combustion engine under clearly defined driving conditions. The result is a significant optimisation of engine power and response ensuring even more dynamic acceleration whenever required. BMW ActiveHybrid technology thus supports the BMW EfficientDynamics development strategy in a particularly intelligent manner, offering even greater driving pleasure on less fuel as well as cleaner emissions. BMW ActiveHybrid is an important building brick within the BMW EfficientDynamics development strategy as a whole. Pursuing this strategy, the BMW Group has indeed introduced a wide range of efficiency-boosting features in series production throughout the entire model portfolio, thus achieving unique progress the world over in the reduction of fuel consumption and emissions. Sales of BMW cars with EfficientDynamics since the year 2007 already exceed a million units. Accordingly, this broad-scale strategy lauded on many occasions through significant prizes and awards has led to a substantial reduction of average fuel consumption by the BMW car fleet. Parallel to this trendsetting strategy, the BMW Group is developing hybrid technology along various lines for various vehicle segments. The objective of this elaborate development process is to create hybrid systems significantly reducing fuel consumption while maintaining the driving dynamics so typical of the brand, in this way living up to the great demands made of a BMW in every respect. Pursuing this strategy, two models with BMW ActiveHybrid technology will be reaching production level in 2009 alone. The perfect starting point: the world’s most Efficient luxury performance saloon. The BMW Concept 7 Series ActiveHybrid is based on the new BMW 7 Series already ranking right at the top in its class in standard trim in terms of efficiency. The new luxury performance saloon from the world’s most successful manufacturer of premium cars thus lives out the demanding objectives of the BMW EfficientDynamics development strategy in particularly convincing style also in this segment. Compared with their predecessors, all models in the new BMW 7 Series stand out in providing both enhanced performance as well as a significant reduction of fuel consumption and exhaust emissions. In their respective performance class, the three engines available right from the start upon the market launch of the new 7 Series rank right at the top worldwide in terms of efficiency. In addition, all models in the BMW 7 Series come as standard with a wide range of BMW EfficientDynamics technologies including Brake Energy Regeneration, on-demand control of the engine’s ancillary units, intelligent lightweight construction, active aerodynamics provided by air flap control, and tires with reduced roll resistance. And last but certainly not least, all engine variants in the new BMW 7 Series comply in full with the EU 5 emission standard. Given these qualities, the new BMW 7 Series from the start offers an ideal foundation for setting the standard worldwide both in the luxury segment and in the hybrid market through an optimum combination of the most advanced BMW ActiveHybrid technology. Another essential feature of the BMW Concept 7 Series ActiveHybrid is that this unique model offers such a significant increase in efficiency over the regular production model without in any way giving up the well-known qualities of BMW’s luxury saloon. Not to be seen from outside, BMW ActiveHybrid technology offers the driver the significant benefits of a new drive concept without in any way influencing the motoring comfort, luxurious ambience, and safety this truly outstanding saloon is able to provide. And when it comes to everyday driving qualities, the concept is once again just right for full enjoyment and driving pleasure in every respect, without the slightest restrictions. BMW ActiveHybrid technology integrated the intelligent way. Presenting the BMW Concept 7 Series ActiveHybrid, BMW is introducing a hybrid car which, through its harmoniously balanced drive components, will fi t perfectly into the model range of BMW’s new luxury performance saloons. The driving experience and motoring comfort reflect the character of this outstanding model line, with new highlights in terms of both driving dynamics and efficiency – as on BMW’s conventional model variants, too. Quite simply, this is because hybrid technology BMW-style stands for superior dynamics combined with outstanding efficiency forming a perfect symbiosis with the sheer supremacy of the BMW 7 Series. All this is made possible by combining an eight-cylinder petrol engine for the first time with a mild hybrid concept. Specifically this approach has been chosen here since the savings potential offered by hybrid technology increases with the output and performance of the combustion engine used, and because large-capacity power units are of particular significance in the premium segment. Focusing initially on smaller cars, BMW has already introduced solutions in the context of EfficientDynamics serving to significantly reduce fuel consumption and not in any way increasing the cost of ownership for the customer. BMW’s current diesel models in this segment, for example, thanks to BMW EfficientDynamics, ensure fuel consumption and emission ratings achieved by other manufacturers with their hybrid cars only on a far lower level of output and performance. In the medium term the development of hybrid systems by the BMW Group tailored to individual models will also lead to solutions in segments offering significant advantages in both fuel economy and driving dynamics so typical of BMW. And at the same time the larger number of models produced will help to reduce the additional cost of hybrid technology. Mild hybrid and the combustion engine form an ideal match in the BMW Concept 7 Series ActiveHybrid as is already the case in the Concept X6 ActiveHybrid combining a full hybrid concept with an eightcylinder petrol engine. Taking these different approaches, BMW is already demonstrating the broad-scale application of hybrid technology, proving that in this area, too, model- and concept-specific solutions will pave the way towards maximum efficiency in all segments of performance and individual vehicles. Consistent optimisation: BMW ActiveHybrid and the V8 power unit with Twin Turbo and High Precision Injection. Like all power units in BMW production cars, the combustion engine featured in the BMW Concept 7 Series ActiveHybrid has been developed in the context of BMW EfficientDynamics. In the BMW 750i this all-aluminum power unit offers all the qualities typical of an eight-cylinder in incomparably sporting and, at the same time, comfortable style, combining power and traction from low engine speeds with impressive pulling force throughout a wide range of engine revs. The power and performance characteristics of the new V8 power unit result primarily from BMW’s innovative Twin Turbo technology. This unique technology featured for the first time on an eight-cylinder gasoline engine, with two turbochargers not fitted at the outside, but rather directly in the V-section of the engine and supplying four cylinders with compressed air in each case, ensures unparalleled spontaneity in responding to the accelerator pedal. High Precision Injection, in turn, ensures highly Efficient use of fuel, the second generation of direct gasoline injection introduced by BMW incorporating piezo-injectors fitted in the cylinder head directly next to the spark plugs and delivering fuel to the combustion chambers at a pressure of 200 bar. This concept alone makes the supply and dosage of fuel extremely precise, the V8 power unit with Twin Turbo and High Precision Injection achieving the highest level of efficiency worldwide in the eight-cylinder segment. This outstanding efficiency is also attributable to the use of BMW EfficientDynamics in and around the engine, with features such as Brake Energy Regeneration, on-demand management and control of ancillaries including an a/c compressor operating only when required, and the use of on-demand pump technology on the car’s suspension control systems. This intelligent energy management also comprises the electrification wherever possible of comfort functions running on electrical energy generated in particular by Brake Energy Regeneration. Use of electric power generated without consuming fuel in the interest of even greater efficiency. Given all these qualities, intelligent alternator control ensures the generation of electricity from energy otherwise wasted in the brake system as heat dissipated into the environment. Now, therefore, the fuel contained in the energy burnt is used to a much higher degree for ensuring genuine driving dynamics on the road, helping to improve the car’s acceleration to an even higher level and optimising the efficiency of the drive system under all load conditions. The principle of Brake Energy Regeneration is applied in the BMW Concept 7 Series ActiveHybrid more consistently than in any production vehicle so far, giving the car an unusually high standard of all-round efficiency and fuel economy. In this case the conventional alternator is replaced by the electric motor fully integrated in the transmission housing and delivering electricity in overrun and under application of the brakes through the likewise fully integrated power electronics to the lithium-ion battery. The electric motor integrated in the transmission housing thus ensures far greater efficiency in the generation of electric power than an alternator drawing energy directly from the combustion engine and, as a result, reducing its overall standard of efficiency. BMW ActiveHybrid technology is also superior to a conventional alternator through its own, inherent efficiency, the energy yield produced by the electric motor through Brake Energy Regeneration alone exceeding the normal standard roughly ten times. The innovative energy storage technology of the lithium-ion battery featured in the BMW Concept 7 Series ActiveHybrid also provides the option to store a much greater amount of electrical energy available virtually free-of-charge, then providing this energy on a permanent basis for all kinds of vehicle functions and therefore exceeding the performance of conventional battery units by far. The progress achieved by BMW in the area of energy storage thus allows electrical operation of ancillary units to an extent far beyond the standard possible so far in a production car.

Fixed.

I wish the BMW marketing people would grab Chris Bangle and all light themselves on fire.

Screw the poor!!!

Dude, don't be hatin'. Those graphics are at least the best in the industry. I really wish GM would get better with theirs, because the days of "4x4" or "Z71" or "GTR IS 2000KR-GR SiR" is so over.
