The latest BMW Car for the EfficientDynamics philosophy.

Woodcliff New Jersey, 29 August 2009, 6pm For decades, BMW has made the reduction of and fuel consumption a key part of its development strategy, just as to the dynamic ability of each BMW been a lasting, sustained value. BMW s EfficientDynamics engineering the pursuit of an enhanced, athletic experience while simultaneously the consumption and emissions of each resulted in the most dramatic in fleet consumption of any automaker 1990 through 2005, to an Environmental Defense study.

the BMW Vision concept car clearly that the EfficientDynamics objectives are compatible when applied to a car. Conceived as a 2+2-seater plug-in full-hybrid technology, unique car combines the performance of a BMW M with a standard of fuel and emission management that even the current levels by the latest small cars. outstanding result is made by the combination of BMW ActiveHybrid components an extremely economical combustion and outstanding aerodynamic qualities.

BMW EfficientDynamics is the result of a clean-sheet process to ensure that the achievements were made in the of efficiency, driving pleasure, and emotional design. BMW Vision is the most comprehensive implementation of the philosophy seen so far. The provides a top speed limited to 155 mph, with acceleration to 100 in 4.8 seconds.

Average fuel in the EU test cycle is 3.76 kilometers, equal to 62.6 and the CO2 emission rating is 99 grams per CO2 emission management is even outstanding when driving in the mode after charging the from a plug-in source: all emissions in the generation of electricity account, as prescribed by the EU formula, the car s rating is just 50 grams per

Through this unique of driving pleasure and fuel the BMW Vision EfficientDynamics concept car demonstrates the potential of BMW ActiveHybrid which makes its world at the 2009 Frankfurt Motor in the BMW ActiveHybrid X6 and BMW ActiveHybrid 7 production

The power and performance are made by combining a fuel-efficient 3-cylinder with one electric motor on axle. The intelligent combination of units, together with controlled energy management, enhances the dynamic performance and the of the car. Overall system is 356 horsepower, and peak torque is 590 The special arrangement of the two motors and engine allows all-wheel when driving in all-electric

The result is minimum power and a harmonious transmission of the power under all conditions.

In its design, BMW EfficientDynamics for the first time the dynamic look of a BMW sports car to a vehicle. Developed with of experience in Motorsport, the body of unique sports car is a result of lightweight technology and aerodynamic In the design of the interior, the focus was on both the fascinating driving and, in particular, on transparent, technology and maximum reduction of

Turbodiesel engine with specific output. The combustion is a cutting-edge turbodiesel featured for the time in the BMW Vision EfficientDynamics car. Displacing 1.5 liters on cylinders, the engine consistently the downsizing principle of using a small engine combined a turbocharger to reduce fuel

Through its compact dimensions, the fits conveniently in front of the axle like in an agile sports car, despite the two at the rear. Fuel is injected by the generation of High Precision Injection, and the turbocharger features intake geometry for maximum Engine output is 163 hp with torque of 214 lb-ft.

The specific of 109 hp per liter sets a new benchmark in technology. The power delivered by the is conveyed to the rear axle by of a double-clutch transmission (DCT). advanced transmission technology, already offers a particularly driving experience in BMW s M3 and Z4 Roadster, the driver to shift gears the slightest interruption of power.

BMW Vision EfficientDynamics features a version of BMW s DCT with six speeds for efficiency and flexibility.

Two electric for full-hybrid drive. The combustion is supplemented by two electric motors. applying the BMW ActiveHybrid philosophy, engineers followed the principle of of Hybrid, choosing the optimum of a hybrid synchronous motor on the axle and a full-hybrid system at the

In this concept, the driver from the efficiency of the electric over a far wider speed than with a conventional car. The rear axle with a second-generation full-hybrid corresponding to the technology in the BMW ActiveHybrid 7 model. The compact electric positioned between the diesel and the DCT outputs a consistent 33 horsepower and is to reach a peak of up to 51 hp. Maximum for the rear electric motor is 214 the power, either supporting the engine or in all-electric motoring.

coasting or applying the brakes, the motor acts as a generator and electric power to the lithium-polymer in the car. The electric energy in this way is therefore captured any additional consumption of fuel the principle of Brake Energy Energy wasted on the brakes of a car is thus saved within the new system for subsequent use in driving the

A second electric motor on the front axle. This a hybrid synchronous motor, continuous output of 80 horsepower and torque of 162 lb-ft. Extra of 112 horsepower is available for a period of up to 30 and, for a 10-second burst, the motor is able to develop 139

The power is transmitted through a single-speed reduction gearbox.

BMW EfficientDynamics is able to run completely electric power, with the of the turbodiesel engine alone, or an infinite combination of the three sources. Depending on driving the two electric motors may be used for accelerating and for regenerating energy applying the brakes and while This principle ensures energy management, with the status of the lithium-polymer battery remaining within the optimum When accelerating, the electric help to boost the car for even performance, ensuring immediate and a significant reduction in fuel

For a short time, such as in maneuvers, the cumulative maximum of all three engines increases to 356 hp, maximum torque generated by the engines reaching 590 lb-ft.

battery for electrical energy. The cells featured in BMW Vision are housed in a chassis element from front to rear the middle of the car. The front is the lithium-polymer complex, an ongoing of the lithium-ion battery.

Overall, BMW EfficientDynamics comes with a of 98 lithium-polymer cells, each a capacity of 30 amp/hours and developing output of 600 Amps at a voltage of 3.7 V. For a of 30 seconds, each cell is able to develop maximum of 1,200 Amps.

Serial of the lithium-polymer cells serves to nominal voltage of 364 volts, the storage capacity of the battery is kW/h. With an unusually discharge capacity of 80 percent, the delivers 8.6 kW/h for driving the This superior performance on overall weight of the entire storage system of just 187 lb.

A advantage is that through optimum dimensions tailored to the qualities and features of the car, the cells, together with the strategy chosen with a of forward looking energy reduces the thermal load on the battery to such an extent there is no need for active

Plug-in solution: convenient of the electric power system a conventional power socket. Energy Regeneration captures power generated while without additional fuel which is subsequently used to power to the electric motors and network. A further option is to the lithium-polymer cells to a conventional socket for a simple and efficient process, using a plug-in in the front-right wing of the car. to a standard EU power outlet V, 16 Amps), the system requires a of 2 hours to fully charge the cells.

And wherever a power with higher voltage and (380 V, 32 Amps) is available, the time is an even shorter 44

In addition to electrical energy BMW Vision EfficientDynamics comes a conventional fuel tank at the end of the central chassis tunnel, a capacity of 6.6 gallons. Running on fuel alone, BMW Vision is able to cover a distance of 400 miles with its combustion Benefitting from an extra of up to 31 miles in the all-electric mode, the car an overall range of approximately 431

As a result, this unique car offers all the requirements for using with maximum efficiency and at the time experiencing the dynamic typical of BMW without any restriction of driving qualities.

Performance, efficiency and emission management new dimensions in hybrid technology. The delivered by the two electric motors and diesel 3-cylinder engine the BMW Vision EfficientDynamics concept a of performance superior to anything so far by a hybrid vehicle. Acceleration a standstill to 100 km/h, for example, in just 4.8 seconds and the car could its electronically-limited 155 mph top speed.

At the same fuel efficiency and emission now reach a standard only if at all, by far less powerful cars conceived for city and short distances. Applying the of the EU test cycle, BMW Vision offers average fuel equal to 62.6 mpg. CO2 in turn, are 99 grams per kilometer.

consumption and emission figures are on a consistent internal power meaning that the batteries and media for electrical energy the same charge level the entire test cycle the same level at the beginning and and are charged while driving by the car s on-board systems.

As a plug-in BMW Vision EfficientDynamics is able to the entire drive cycle for fuel consumption also its combustion engine completely off. Then, to subsequently the lithium-polymer cells to the same as when setting off, all the has to do is connect the car to an external power To determine the consumption of electric the only requirement is to compare the level of the battery before and the test cycle.

Applying measurement process, the BMW Vision concept car consumes 17.5 per 100 kilometers, equal to a CO2 emission of just 50 grams per kilometer in the EU cycle.

To determine the total of CO2 emissions when driving in the mode, new legal standards for the level of fuel consumption are being prepared for hybrid and cars with a plug-in supply. Applying this method, the CO2 emission ratings by BMW Vision EfficientDynamics are reduced to just one-third of the original of 99 grams per kilometer. Clearly, significant reduction of emissions up a new dimension in BMW s EfficientDynamics development in this unique concept

Aerodynamic qualities reflecting BMW s experience. BMW Vision EfficientDynamics takes a new approach in its design and the body and the interior clearly the unique combination of supreme and the sporting performance of the brand. BMW s design language, this car visualizes both highly aerodynamics and intelligent lightweight

In its design, BMW Vision EfficientDynamics from the usual low-emission car The principle of form follows is not just for the overall look of the but embraces each and every Measuring 48.8 in height and a sweeping, arch-like roofline, BMW EfficientDynamics offers the slender of a classic Gran Turismo.

With the combustion engine in front of the rear axle, the have succeeded in giving the car a low front end, with the of air being further smoothened by louvers in front of the radiator, close completely when the for cooling air is low. This function follows in the footsteps of the air flap control already as a feature of BMW EfficientDynamics in some of BMW s production models. As a further BMW Vision EfficientDynamics guides air and exactly as required into the car an active air intake at the front.

details in the design of the body are on the know-how BMW has gained in Motorsport, a of body elements serving as air and guide vanes. Designed as for example, the A-pillars serve to the flow of air in the same way as the rear with their wing The floor of the car is fully covered front to rear and from one to the other, thus maintaining a surface to avoid any air swirl to increase fuel consumption.

openings around the front air dam the air flowing specifically into two ducts leading inside the air dam to the wheel arches where the air out again through a very aperture at high speed, just next to the outer flanks. This air jet rests on the wheels like a curtain and is referred to most appropriately as the air It provides a highly stabilizing

Thanks to the consistent construction strategy applied on the curb weight is 3,076 lb, the center of gravity remaining low. In its power-to-weight ratio, the BMW EfficientDynamics concept car is far superior to all hybrid cars, achieving the standard as extremely dynamic cars with a conventional engine. Carrying a maximum of 981 lb, this unique 2+2-seater is suited for everyday traffic.

capacity of 5.3 cu ft, in turn, allows the and passengers to conveniently take two golf bags. And to meet loading requirements the backrests of the two seats may be tilted down to provide extra storage Emotional design through shapes and layering technology. the innovative drive concept of unique car, the design of BMW EfficientDynamics likewise takes a new in combining functional progress a most powerful emotional

This has been achieved the close cooperation of BMW s Design and Development Divisions starting at an point and continuing consistently the entire development process. The is a brand-new vehicle architecture the drive components as well as the and interior elements perfectly and matched to one another with flexibility and individual style. A integrated design philosophy provided new options in using design principles connecting the and the interior and providing an interacting between the two areas. Sculptural language giving BMW Vision a fully harmonized, complete ensures the proportions typical of a BMW car.

The front, side, and roof areas, for example, smoothly into one another. contoured surfaces and shapes, in create highly attractive and shade effects accentuating the and sporting character of the car in an emotional Layering technology developed by the BMW Design Division acts as the guideline in designing the exterior and Applied for the first time in design, this technology one surface on top of the other, creating smooth seams and joints to the number of components and, the weight of the car.


As a result, BMW EfficientDynamics meets the most aerodynamic requirements without any additional body elements, through the structure of the surfaces for a smooth flow of air. innovative lightweight construction and orientation to the driver. In the design of the innovative layering technology an unprecedented symbiosis of function and shapes intentionally reduced to a consistently implementing and visualizing the principle also inside the

Specific components such as the air vent not only serving to motoring comfort but also as part of the cockpit, perform functions in one. This is then presented visibly the car, the use of particularly sophisticated providing a highly attractive of innovation in technology and quality to the eye and the touch of the surface. This of lightweight construction and individual also comes out clearly in the of the controls and switches, with a band, for example, running the aluminum gear selector on the center console. Materials lightweight technology and all the qualities are also to be admired all round the of BMW Vision EfficientDynamics, giving the car an generous feeling of space for a

The body-contoured seats, for example, are up of a kevlar shell, a backbone and seat padding with fillings. Clearly, this alone ensures comfort at a weight. The driver s and front s seats are connected firmly to the console to form a joint landscape , while the rear anchored on the floor would to be hovering in space. Natural and light colors on the seat and all interior linings underline the sophisticated and sustainability-oriented atmosphere the passenger compartment.

The instrument is deliberately padded only technical components have to be covered, thus making an contribution to passenger safety in the of a collision. The instrument cluster a fundamental role right the start in the design process, as the starting point for all surfaces the interior and thus creating a powerful rendition of that orientation typical of BMW. light technology: providing signals to the outside and offering ambient illumination inside in a symbiosis.

LED lights at both the and rear end of BMW Vision EfficientDynamics an innovative combination of the symbols of the brand and clear design oriented towards trendsetting The distinctive look of the dual headlights characteristic of a BMW is emphasized in by the use of LED technology. The rear lights are also in their function the design of the entire rear forming part of the rear air and thus merging completely the rear contour. Extremely and compact, the rear lights are up of innovative LED units forming a and consistent red surface when not in Only when used do the light chambers take on the color such as yellow on the indicators.

This innovative light also provides an intense of the exterior and interior, again and further refining the driving This is also why the ambient of the interior comes with new and qualities, the light sources the passenger compartment being fed the positioning lights at the side, the lights and the brake lights, changing the atmosphere created by the within the car as a function of driving The optical impression conveyed by BMW EfficientDynamics also results in areas from the symbiosis of the and interior, eliminating the conventional between the two. The lines the interior, for example, continue on to the design of the engine compartment while in its shape the third light positioned higher up on the car the structure of the glass roof and to the outside where the roofline down gently to the rear.

doors for convenient access to all The doors on BMW Vision EfficientDynamics up like bird s wings, on pivots in the front roof at the level of the side direction Since the car has no B-pillars, the large cutouts ensure convenient also to the rear seats. The on the doors also provide the for the exterior mirrors, thus an ideal combination of function and design.

The structure of the doors is characterized by several layers of on top of one another and the optical and functional of the interior and exterior this is able to offer. Made up of layers, the overall structure the outer glass surface, an load-bearing layer, and the interior with its particularly smooth and fl owing forms clearly to the passengers, layering technology therefore, opening up new perspectives. The glass surfaces extending far on the body also provide a optical impression of the low seating close to the road. And at the same a stable sidebar ensures the stiffness and crash safety required on every vehicle. to the inside at its central point, safety element also as an armrest.

This interplay of the layers also helping to the weight of the car continues on the trim bar along the door and extending out of the finally flowing into the door opener on its path inside to outside. Clear on the essential: 3-dimensional Head-Up Layering technology is also on the displays in the instrument cluster and in the Display developed to an even standard on BMW s new concept car. The now creates a powerful impression of dimensions, at the same time the option to present various more in the front or more in the depending on their relevance and driving conditions. The Head-Up projects information important to the on to the windscreen.

Indeed, innovative technology even allows the presentation of several views in dimensions, keeping, the gauge visible in the background while the information on route guidance or signals from BMW Night for example, are shown in the foreground. The in which such signals depends on the driving mode by the driver, the display technology, depending on the driver s personal enhancing a particularly sporting, a comfort oriented, or an efficiency-based of motoring. Through its design the BMW Vision EfficientDynamics concept car shows that highly individual mobility may by all means be in emotional style. BMW already models in all vehicle segments compared with the competition, the lowest level of fuel and emissions combined with power and performance. And now BMW Vision confirms BMW s commitment to offer a combination in future of unique pleasure and optimum qualities in the use of natural resources.

In the design process the need for management is borne out most by the GINA (Geometry and Functions in Augmentation) concept developed by the BMW In this case maximum freedom sets the foundation for solutions challenging the conventional and the requirements of the future. This the GINA principle particularly for developing visions for the future both the wish for emotional and individual character as well as the for sustainable management and efficiency. the dimensions of its wheels through the of the rear lights and all the way to the configuration of the BMW Vision EfficientDynamics therefore a number of details both and inside which, going far conventional solutions, open up a new to maximum efficiency and that ability typical of BMW.

energy management adjusting to requirements. With the individual components on board BMW Vision being networked with one conditions are perfect for implementing a system of energy management information gathered by the sensors of the assistance units fitted in the Data provided, for example, by the sensor or Active Cruise with its Stop Go function as as by the navigation system, and subsequently by the central control unit, an overview of current and upcoming conditions. Then, evaluating data, the on-board computer is to forecast driving conditions on the of road immediately ahead, calculations serving to prepare the car for requirements and make efficient use of the available through optimum of all systems. Should the high-performance computer establish, for example, the driver is about to take the the power used for running the system is reduced for a certain in advance, on the assumption that the increase in coolant temperature from such an energy-saving will quickly be set off by the higher of the car on the motorway.
