Bmw 7-Series (2009)

The launch of the fifth generation of the BMW 7-Series sets a new benchmark in automotive luxury, technical innovation and class-leading driving dynamics, combined with emissions reducing and fuel saving technology.

The flagship of the BMW model range debuts in November with a host of world firsts and will initially be offered with a choice of three powerplants, one diesel and two petrol engines. The two petrol-powered cars will be offered with a long-wheelbase body too. All three engines produce more power yet use less fuel and produce less emissions than any rival premium product.

The BMW 730d sets a new benchmark in terms of drivetrain performance. The new all-aluminium 3.0-litre straight-six cylinder diesel engine produces 245hp at 4,000rpm. Its effortless real world driving smoothness comes courtesy of a peak torque figure of 540Nm attained from 1,750rpm through to 3,000rpm.

The 2,993cc powerplant posts the lowest ever CO2 figure of any BMW 7-Series before it and it is also the most economical 7-Series ever. Its 192g/km emission figure is class-leading for conventionally powered luxury cars, while no other competitor comes close to its 39.2mpg combined consumption figure. It can accelerate from zero to 62mph in 7.2 seconds and has a 152mph top speed.

To put the BMW 730d's competitive advantage in context this luxurious vehicle records near identical fuel consumption and CO2 emissions to the Mercedes C320CDi - a car that is two market segments below the BMW 7-Series and is smaller and lighter than the BMW.

The impressive performance of the 730d is, in part, possible due to third-generation common-rail direct injection incorporating piezo injectors that operates at a peak pressure of 1,800 bar. This system ensures a near perfect combustion process. Weighing 185kgs the new six-cylinder diesel engine is also 5kgs lighter than its predecessor.

The BMW 730d is set to be the biggest seller in the UK, accounting for approximately 85 per cent of sales.

The BMW 750i and BMW 750Li are the range flagships. The new 4,395cc V8 engine from the recently launched BMW X6, featuring twin-turbochargers and high-precision direct injection technology, produces 407hp from 5,500rpm to 6,400rpm. Impressive figures that are backed up by an equally stunning 600Nm of torque from 1,750rpm to 4,500rpm. Such breathtaking performance sees the BMW 750i accelerate from zero to 62mph in 5.2 seconds (5.3 seconds for the 750Li) before going on to an electronically-limited top speed of 155mph. Consumption on the combined cycle is 24.8mpg, while CO2 emissions equate to 266g/km.

The all-aluminium V8 engine powering the 750i and 750Li also features its own world first - twin-turbochargers and catalysts that are placed within the V-space of the engine block. This not only optimises packaging but the reduction in manifold length and larger cross sections mean the engine breathes better for enhanced performance. Double-VANOS variable valve technology and high-precision direct injection technology further aid engine performance to the degree that all the innovations combine to offer a V8 engine that has an equivalent output of a traditional 12-cylinder unit.

Aimed at customers who prefer the characteristics of a petrol-powered BMW six-cylinder engine, the BMW 740i and 740Li are also offered. Using an internationally-acclaimed 2,979cc powerplant, the BMW 740i musters 326hp and 450Nm of torque for rapid yet serene performance. The twin-turbocharged engine features high-precision direct injection and Double-VANOS variable valve technology to achieve optimum performance. The 3.0-litre BMW 740i and 740Li post combined fuel consumption figures of 28.5mpg and 28.3mpg respectively, while returning emissions figures of 232g/km and 235g/km.

All BMW 7-Series models come with a six-speed automatic gearbox as standard.

EfficientDynamics

The launch of the new BMW 7-Series completes the line-up of the entire BMW range now being equipped with EfficientDynamics technologies fitted as standard. With its roof, doors, bonnet and side panels all made from aluminium to dovetail with the principle of lightweight engineering, the BMW 7-Series also has other innovative class-leading technology which improves engine performance, while cutting fuel consumption and emissions.

Brake Energy Regeneration uses the engine's power on overrun, such as braking, to charge the battery for the car's electrical circuit. When the driver is accelerating the alternator disengages so all of the engine's power is channelled towards the car's performance. Other ancillaries, such as the air-conditioning compressor, are also able to disengage to improve the all round performance of the car. This intelligent use of drivetrain power is why EfficientDynamics technology has helped the BMW 7-Series become a class-leader in terms of performance, fuel consumption and emissions.

World firsts

The BMW 7-Series' drivetrain superiority is reinforced with a plethora of automotive firsts. All BMW 7-Series can now be specified with the world's first Head-up Display incorporating a speed limit warning system. A camera mounted on the back of the rear view mirror scans oncoming road signs to alert the driver of any impending speed restriction. The BMW 7-Series is also the world's first car available with a Side View camera system that operates in conjunction with Park Distance Control. The system provides an overview of traffic conditions on the iDrive display so the driver can negotiate a partially obscured junction, leave a car park or drive through a narrow gate with absolute confidence.

The new BMW 7-Series can be specified with the world's most advanced Night Vision system in a production car. BMW was the first manufacturer to fit a Night Vision system to a premium car and it has now upgraded this package to include an individual person recognition system in another world first. A control unit within the system analyses video data of human behaviour as part of the Night Vision camera's reach and can subsequently alert the driver if it detects a human is moving into the path of the vehicle.

Building on the impressive list of innovations, the BMW 7-Series is the first BMW to feature Lane Change Warning combined with Lane Departure Warning. The latter is a system that first appeared on 5 and 6 Series models and uses a camera to monitor road markings. Should the driver start to stray out of lane, a gentle vibration of the steering wheel would provide an alert. However, courtesy of cameras located in the door mirrors, Lane Change Warning adds another tier of driver safety. The two cameras constantly scan the blind spot either side of the vehicle, up to a distance of 60 metres, and alert the driver to the presence of another vehicle with a triangular symbol in the door mirror.

Completing the host of innovations is speed-related Integral Active Steering. A car specified with this optional equipment allows the rear wheels to turn by up to 3º. At slow speeds it is highly manoeuvrable, while at a faster pace it offers enhanced composure and driving dynamics. BMW's flagship car is also the world's first to come with full-scale Internet connectivity.

Tailormade driving dynamics

The latest generation BMW 7-Series is the first to have Dynamic Driving Control featuring Dynamic Damping Control as standard. Dynamic Driving Control is the umbrella function that lets a driver customise the characteristics of his or her car. As part of this Dynamic Damping Control can bet set in comfort, normal or sport modes, but, for the first time, with the added benefit that these settings are infinitely variable depending on driving style and road surface condition. Depending on selected mode the throttle response, gear change speed and steering feel are also altered at the same time.

To aid driving dynamics and comfort the BMW 7-Series is the first BMW Saloon to feature race car-like double-wishbone front suspension. This arrangement allows engineers to fine-tune the suspension for the best kinematic configuration. The rear suspension consists of a five-link arrangement made of aluminium which can be further optimised with the inclusion of Adaptive Air Suspension.

The 2009 BMW 7-Series comes as standard with Dynamic Stability Control + featuring additional functions such as Hill-Start Assistant, Brake Drying, Brake Pre-tensioning, Soft-stop and Brake Fade Compensation. Dynamic Traction Control can be activated via a button to enable spirited driving or greater traction of slippery surfaces such as snow and ice.

A new interior

The new BMW 7-Series comes with one of the most luxurious interiors of any premium car. In addition to a new iDrive controller and larger 10.2-inch screen, owners will be able to programme frequently selected radio stations or navigation destinations on favourite buttons located on the centre console. For the first time on a BMW the instrument cluster comprises a high-resolution colour display with Black Panel technology. This new style of display makes for greater character clarity and, when not in use, forms a smooth, homogenous black surface that gives the interior an added level of modern elegance.

With its 40Gb hard drive, the BMW 7-Series is the first production car in the world that enables a customer to upload their favourite music to be stored on the vehicle. In excess of 100 albums can be saved in this way for the driver's enjoyment. Four-zone automatic air-conditioning can be specified and, for the first time, the BMW 7-Series can have a rear seat ventilation system combined with massage function. The air-conditioning system feeds cool air to the seat squab and backrest while twelve massage bubbles gently kneed the occupants' upper body.

The BMW 7-Series comes with BMW ConnectedDrive with enhanced BMW Assist and BMW TeleServices as standard. BMW Assist is the reactive safety blanket that automatically dials the emergency services if the driver is involved in an accident. For the BMW 7-Series this life-saving system has been improved so that it can now tell the emergency services the severity of the accident and the likely injuries of those inside. BMW TeleServices sees the 7-Series automatically communicate with a call centre if it the car is due a service or a potential fault is detected. A dealer will then contact the owner to arrange a convenient time to rectify this.

The BMW 7-Series goes on sale in the UK on 15 November, 2008.

Bmw M3 Race Version (2009)

BMW presented the racing version of the new BMW M3 at the 2008 Chicago Auto Show. Powered by a 485 bhp eight cylinder engine, this impressive race car has been designed to compete in the American Le Mans Series (ALMS) beginning in 2009. The car is based on the fourth generation of the BMW M3, the high-performance sports car produced by BMW M GmbH.

BMW Motorsport Director Mario Theissen says: "With the sporting genes of the production BMW M3 being clearly evident, developing a racing version of the car was the next logical step. The fact that the road-going vehicle is fitted with a V8 engine as standard provided us with an ideal base. However, the BMW M3 is more than a race car, it has achieved legendary status amongst race fans across the globe. I am convinced that this unique story of the BMW M3 racing cars will now be expanded upon by the addition of further chapters."

BMW's 2009 entry into the American Le Mans Series will be driven by a partnership between BMW of North America, LLC and Rahal Letterman Racing, co-owned by US motorsport legend Bobby Rahal.

"We are very pleased to be returning to the American Le Mans Series with our latest generation BMW M3," states Tom Purves, Chairman and CEO, BMW of North America. "Sports car racing has been part of BMW of North America's history practically from day one. Just two weeks after the company was incorporated in March 1975, a BMW CSL won the Twelve Hours of Sebring. We are confident that the fourth generation M3 will continue the legacy of its two predecessors which combined to win six manufacturer's championships over nine seasons in US sports car racing. As it has been in the past we believe the ALMS is the ideal venue to showcase the potential of the newest BMW M3."

Echoing that sentiment Bobby Rahal adds, "BMW has an illustrious racing heritage. Rahal Letterman Racing is eagerly anticipating, not only becoming part of that heritage, but helping to enhance it. Our dedication to this project will be without equal and we look forward to racing at the front of the grid with BMW in the years to come."

Martin Birkmann, Motorsports Manager, BMW of North America, adds: "We are very excited to announce our return to the American Le Mans Series with the 4th generation M3 at the same time as the road car hits the BMW showrooms. We are also excited about our partnership with Rahal Letterman Racing. The ALMS offers racing where we can compete against the finest and most renowned automotive brands from Europe and the US. Motorsport is deeply ingrained in the BMW DNA and we are pleased to partner with an organization which shares that same heritage. Rahal Letterman Racing is the perfect partner to be behind the wheel of our new BMW M3 racing effort."

The BMW M3 Race Version: Sportiness personified.
In the course of developing the race version of the BMW M3, BMW's engineers were faced with an ambitious task: to improve upon the sportiness of an already sporting car. A better base would, though, be difficult to find. In standard form the vehicle delivers powerful dynamics and sporting aesthetics. Thanks to an eight cylinder engine producing 414 bhp, BMW's customers are provided with a unique driving experience.

Those engine blocks, cast in BMW's light alloy foundry in Landshut - the very source of BMW's Formula One castings - selected for race duty need to withstand even more power: the BMW P65 race engine delivers 485 bhp.

In order to enable the BMW M3 to make full use of this performance on the race circuit, the experts in Munich have not concentrated solely on the engine, but have race-tuned the chassis as well. The race version of the BMW M3 is wider and significantly lighter than its production equivalent, enabling it to perfectly transmit the power of its V8 to the track. Widespread use of carbon-reinforced plastic (CRP) provides proof of substantial weight reduction. As with the production version, the race car's roof is manufactured from this high-tech material.

The race version of the BMW M3 is clearly aimed at the top echelon of motorsport. As such, it is no surprise to discover that in the course of its development, begun in mid-2007, numerous Formula One techniques were applied. These include computational fluid dynamics (CFD) and wind tunnel analyses, both of which have ensured the best possible aerodynamic package for the BMW M3.

Intelligent control systems have been incorporated throughout the BMW M3. The POWER400 control unit actuates all the accessories fitted to the car, such as lights, wipers, etc., via two bus systems. Traditional relays and fuses are thus eliminated, ensuring considerable weight saving, improved reliability and ease of application. The functions of the BMW P65 engine are managed by an ECU 408 electronic control unit, developed in-house by BMW Motorsport. The software and applications, too, have been developed by the experts in Munich.

An intensive test program, during which the performance of the race car will be honed by BMW Motorsport, looms for the BMW M3 over the coming months. Development drivers will be BMW works drivers Andy Priaulx (GBR), Jörg Müller (GER) and Augusto Farfus (BRA), currently racing in the FIA World Touring Car Championship (WTCC). The aim is, after all, for the BMW M3 to be an immediate front-runner upon its comeback to the American Le Mans Series.

Bmw EfficientDynamic Concept (2009)

For decades, BMW has made the reduction of emissions and fuel consumption a key part of its product development strategy, just as enhancements to the dynamic ability of each BMW have been a lasting, sustained brand value. BMW's EfficientDynamics engineering philosophy - the pursuit of an enhanced, athletic driving experience while simultaneously lowering the consumption and emissions of each vehicle - resulted in the most dramatic drop in fleet consumption of any automaker from 1990 through 2005, according to an Environmental Defense study.

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

BMW EfficientDynamics Concept is the result of a "clean-sheet" development process to ensure that the correct achievements were made in the areas of efficiency, driving pleasure, technology, and emotional design. BMW EfficientDynamics Concept is the most comprehensive implementation of the EfficientDynamics philosophy seen so far. The powertrain provides a top speed limited electronically to 155 mph, with acceleration to 100 km/h in 4.8 seconds. Average fuel consumption in the EU test cycle is 3.76 liters/100 kilometers, equal to 62.6 mpg, and the CO2 emission rating is 99 grams per kilometer. CO2 emission management is even more outstanding when driving in the all-electric mode after charging the battery from a plug-in source: Taking all emissions in the generation of electricity into account, as prescribed by the EU formula, the car's emission rating is just 50 grams per kilometer.

Through this unique balance of driving pleasure and fuel efficiency, the BMW EfficientDynamics Concept car clearly demonstrates the potential of BMW ActiveHybrid technology, which makes its world debut at the 2009 Frankfurt Motor Show in the BMW X6 ActiveHybrid and BMW 7 ActiveHybrid production models.

The power and performance are made possible by combining a fuel-efficient 3-cylinder turbodiesel with one electric motor on each axle. The intelligent combination of these units, together with precisely controlled energy management, simultaneously enhances the dynamic performance and the efficiency of the car. Overall system output is 356 horsepower, and peak torque is 590 lb-ft. The special arrangement of the two motors and diesel engine allows all-wheel drive when driving in all-electric mode. The result is minimum power loss and a harmonious transmission of the power available under all conditions.

In its design, BMW EfficientDynamics Concept for the first time conveys the dynamic look of a BMW sports car to a hybrid vehicle. Developed with decades of experience in Motorsport, the body of this unique sports car is a result of intelligent lightweight technology and aerodynamic efficiency. In the design of the interior, the focus was likewise on both the fascinating driving experience and, in particular, on transparent, hands-on technology and maximum reduction of weight.

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

Through its compact dimensions, the 3-cylinder fits conveniently in front of the rear axle like in an agile mid-engine sports car, despite the two seats at the rear. Fuel is injected by the latest generation of High Precision Direct Injection, and the turbocharger features variable intake geometry for maximum efficiency. Engine output is 163 hp with peak torque of 214 lb-ft.

The specific output of 109 hp per liter sets a new benchmark in diesel technology. The power delivered by the turbodiesel is conveyed to the rear axle by means of a double-clutch transmission (DCT). This advanced transmission technology, which already offers a particularly dynamic driving experience in BMW's M3 and Z4 Roadster, allows the driver to shift gears without the slightest interruption of power. BMW EfficientDynamics Concept features a newly-developed version of BMW's DCT with six speeds for maximum efficiency and flexibility.

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

In this concept, the driver benefits from the efficiency of the electric motors over a far wider speed range than with a conventional hybrid car. The rear axle comes with a second-generation full-hybrid system corresponding to the technology in the BMW ActiveHybrid 7 production model. The compact electric motor positioned between the diesel engine and the DCT outputs a consistent 33 horsepower and is able to reach a peak of up to 51 hp. Maximum torque for the rear electric motor is 214 lb-ft, the power, either supporting the diesel engine or in all-electric motoring. When coasting or applying the brakes, the electric motor acts as a generator and feeds electric power to the lithium-polymer battery in the car. The electric energy developed in this way is therefore captured without any additional consumption of fuel through the principle of Brake Energy Regeneration. Energy wasted on the brakes of a conventional car is thus saved within the new power system for subsequent use in driving the car.

A second electric motor acts on the front axle. This engine, a hybrid synchronous motor, offers continuous output of 80 horsepower and peak torque of 162 lb-ft. Extra power of 112 horsepower is available for a period of up to 30 seconds, and, for a 10-second "burst," the electric motor is able to develop 139 horsepower. The power is transmitted through a 2-stage, single-speed reduction gearbox.

BMW EfficientDynamics Concept is able to run completely under electric power, with the power of the turbodiesel engine alone, or through an infinite combination of the three power sources. Depending on driving conditions, the two electric motors may be used both for accelerating and for regenerating energy when applying the brakes and while coasting. This principle ensures efficient energy management, with the charge status of the lithium-polymer battery constantly remaining within the optimum range. When accelerating, the electric motors help to boost the car for even greater performance, ensuring immediate response and a significant reduction in fuel consumption. For a short time, such as in passing maneuvers, the cumulative maximum output of all three engines increases to 356 hp, with maximum torque generated by the three engines reaching 590 lb-ft.

Lithium-polymer battery for electrical energy.
The energy cells featured in BMW EfficientDynamics Concept are housed in a chassis element running from front to rear through the middle of the car. The front unit is the lithium-polymer complex, an ongoing development of the lithium-ion battery. Overall, BMW EfficientDynamics Concept comes with a total of 98 lithium-polymer cells, each offering a capacity of 30 amp/hours and developing continuous output of 600 Amps at a voltage of 3.7 V. For a period of 30 seconds, each cell is even able to develop maximum output of 1,200 Amps.

Serial arrangement of the lithium-polymer cells serves to generate nominal voltage of 364 volts, the gross storage capacity of the battery is 10.8 kW/h. With an unusually high discharge capacity of 80 percent, the battery delivers 8.6 kW/h for driving the car. This superior performance comes on overall weight of the entire energy storage system of just 187 lb. A further advantage is that through their optimum dimensions tailored to the specific qualities and features of the car, the lithium-polymer cells, together with the operating strategy chosen with a concept of "forward looking" energy management, reduces the thermal load acting on the battery to such an extent that there is no need for active cooling.

Plug-in solution: convenient charging of the electric power system from a conventional power socket.
Brake Energy Regeneration captures electric power generated while driving without additional fuel consumption, which is subsequently used to supply power to the electric motors and on-board network. A further option is to connect the lithium-polymer cells to a conventional power socket for a simple and efficient charge process, using a plug-in connector in the front-right wing of the car. Connected to a standard EU power outlet (220 V, 16 Amps), the system requires a maximum of 2 ½ hours to fully charge the lithium-polymer cells. And wherever a power source with higher voltage and amperage (380 V, 32 Amps) is available, the charge time is an even shorter 44 minutes.

In addition to electrical energy storage, BMW EfficientDynamics Concept comes with a conventional fuel tank at the rear end of the central chassis tunnel, offering a capacity of 6.6 gallons. Running on diesel fuel alone, BMW EfficientDynamics Concept is able to cover a distance of approximately 400 miles with its combustion engine. Benefitting from an extra range of up to 31 miles in the all-electric mode, the car offers an overall range of approximately 431 miles. As a result, this unique concept car offers all the requirements for using energy with maximum efficiency and at the same time experiencing the dynamic performance typical of BMW without any restriction of everyday driving qualities.

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

At the same time fuel efficiency and emission management now reach a standard only achieved, if at all, by far less powerful small cars conceived for city traffic and short distances. Applying the criteria of the EU test cycle, BMW EfficientDynamics Concept offers average fuel consumption equal to 62.6 mpg. CO2 emissions, in turn, are 99 grams per kilometer. These consumption and emission figures are measured on a consistent internal power balance, meaning that the batteries and storage media for electrical energy maintain the same charge level throughout the entire test cycle (with the same level at the beginning and end) and are charged while driving only by the car's on-board systems.

As a plug-in hybrid, BMW EfficientDynamics Concept is able to cover the entire drive cycle for measuring fuel consumption also with its combustion engine completely switched off. Then, to subsequently charge the lithium-polymer cells to the same status as when setting off, all the driver has to do is connect the car to an external power grid. To determine the consumption of electric power, the only requirement is to compare the charge level of the battery before and after the test cycle. Applying this measurement process, the BMW EfficientDynamics Concept car consumes 17.5 kW/h per 100 kilometers, equal to a CO2 emission rating of just 50 grams per kilometer in the EU test cycle.

To determine the total volume of CO2 emissions when driving in the all-electric mode, new legal standards for measuring the level of fuel consumption are currently being prepared for hybrid and electric cars with a plug-in power supply. Applying this calculation method, the CO2 emission ratings generated by BMW EfficientDynamics Concept are reduced further to just one-third of the original figure of 99 grams per kilometer. Clearly, this significant reduction of emissions opens up a new dimension in BMW's EfficientDynamics development strategy in this unique concept car.

Aerodynamic qualities reflecting BMW's Motorsport experience.
BMW EfficientDynamics Concept also takes a new approach in its design and streamlining, the body and the interior clearly expressing the unique combination of supreme efficiency and the sporting performance of the brand. Following BMW's design language, this concept car visualizes both highly efficient aerodynamics and intelligent lightweight construction.

In its design, BMW EfficientDynamics Concept differs from the usual low-emission car concepts. The principle of "form follows function" is not just for the overall look of the car, but embraces each and every detail. Measuring 48.8" in height and boasting a sweeping, arch-like roofline, BMW EfficientDynamics Concept offers the slender silhouette of a classic Gran Turismo. With the combustion engine fitted in front of the rear axle, the designers have succeeded in giving the car a very low front end, with the flow of air being further smoothened by active louvers in front of the radiator, which close completely when the need for cooling air is low. This efficient function follows in the footsteps of the active air flap control already used as a feature of BMW EfficientDynamics in some of BMW's current production models. As a further highlight, BMW EfficientDynamics Concept guides air smoothly and exactly as required into the car through an active air intake at the front.

Numerous details in the design of the body are based on the know-how BMW has gained in Motorsport, a number of body elements serving as air deflectors and guide vanes. Designed as ducts, for example, the A-pillars serve to channel the flow of air in the same way as the rear lights with their wing profile. The floor of the car is fully covered from front to rear and from one side to the other, thus maintaining a smooth surface to avoid any air swirl liable to increase fuel consumption. Slender openings around the front air dam guide the air flowing specifically into two closed ducts leading inside the front air dam to the wheel arches where the air comes out again through a very slim aperture at high speed, flowing just next to the outer wheel flanks. This air jet rests on the front wheels like a curtain and is therefore referred to most appropriately as the "air curtain." It provides a highly stabilizing effect.

Overall vehicle concept for a drag coefficient of just 0.22.
To further optimize the aerodynamic qualities of the entire vehicle and keep rolling resistance to a minimum, BMW EfficientDynamics Concept comes with tires and wheels of quite unusual size on a sports car. The tires measure 195/55, while large 21-inch wheels provide a contact surface on the road otherwise offered only by a much wider tire. In combination with the sophisticated axle geometry, this ensures agile driving behavior.

The extra-large wheel covers extending over part of the tire flanks add to the unique, very different look of BMW EfficientDynamics Concept from the side. The blade profile integrated in the wheels serves furthermore to reduce the negative effect of the turning wheels on the overall aerodynamics of the car. In all, these features optimizing the aerodynamic qualities of the car give the BMW EfficientDynamics Concept car a very low drag factor (CX) of just 0.22.

Technological look as a strong impression of intelligent lightweight construction.
In both exterior and interior design, BMW EfficientDynamics Concept stands out clearly as a strong spearhead in technology. Many components of the vehicle are presented in full view expressing the "transparent" character of the car as a powerful visual feature of lightweight technology. The chassis and suspension of BMW EfficientDynamics Concept are made completely of aluminum; the roof and the outer skin on the doors are made almost completely of a special polycarbonate glass automatically darkening as a function of the light shining on the car.

Measuring 181.1" in length, 74.8" in width and 48.8" in height, this unique concept car offers ample space for up to four passengers and their luggage. Thanks to the consistent lightweight construction strategy applied on the car, curb weight is 3,076 lb, with the center of gravity remaining very low. In its power-to-weight ratio, the BMW EfficientDynamics Concept car is far superior to all other hybrid cars, achieving the same standard as extremely dynamic sports cars with a conventional combustion engine.

Carrying a maximum payload of 981 lb, this unique 2+2-seater is fully suited for everyday traffic. Luggage capacity of 5.3 cu ft, in turn, allows the driver and passengers to conveniently take along two golf bags. And to meet additional loading requirements the backrests of the two rear seats may be tilted down individually to provide extra storage space.

Emotional design through sculptural shapes and layering technology.
Reflecting the innovative drive concept of this unique car, the design of BMW EfficientDynamics Concept likewise takes a new approach in combining functional progress with a most powerful emotional impact.

This has been achieved through the close cooperation of BMW's Design and Technical Development Divisions starting at an early point and continuing consistently throughout the entire development process. The result is a brand-new vehicle architecture with the drive components as well as the body and interior elements perfectly coordinated and matched to one another with maximum flexibility and individual style.

A fully integrated design philosophy also provided new options in using harmonized design principles connecting the exterior and the interior and providing an interacting effect between the two areas.

Sculptural design language giving BMW EfficientDynamics Concept a fully harmonized, complete look ensures the proportions typical of a BMW sports car. The front, side, rear and roof areas, for example, flow smoothly into one another. Dynamically contoured surfaces and shapes, in turn, create highly attractive light and shade effects accentuating the light and sporting character of the car in an emotional manner.

Layering technology developed by the BMW Group Design Division acts as the fundamental guideline in designing the exterior and interior. Applied for the first time in exterior design, this technology layers one surface on top of the other, creating very smooth seams and joints to reduce the number of components and, accordingly, the weight of the car. As a result, BMW EfficientDynamics Concept meets the most demanding aerodynamic requirements without using any additional body elements, simply through the structure of the surfaces optimized for a smooth flow of air.

Interior: innovative lightweight construction and unprecedented orientation to the driver.
In the design of the interior, innovative layering technology provides an unprecedented symbiosis of function and stylish shapes intentionally reduced to a minimum, consistently implementing and visualizing the lightweight principle also inside the car.

Specific components such as the central air vent not only serving to enhance motoring comfort but also acting as part of the cockpit, perform several functions in one. This multi-functionality is then presented visibly within the car, the use of particularly sophisticated materials providing a highly attractive combination of innovation in technology and quality clear to the eye and the touch of the surface.

This interaction of lightweight construction and individual well-being also comes out clearly in the design of the controls and switches, with a leather band, for example, running round the aluminum gear selector lever on the center console. Materials combining lightweight technology and all the qualities required are also to be admired all round the cockpit of BMW EfficientDynamics Concept, giving the car an unusually generous feeling of space for a 2+2-seater. The body-contoured seats, for example, are made up of a kevlar shell, a backbone structure, and seat padding with personalized fillings. Clearly, this combination alone ensures comfort at a minimum weight. The driver's and front passenger's seats are connected firmly to the center console to form a joint interior "landscape", while the rear seats anchored on the floor would appear to be hovering in space. Natural materials and light colors on the seat upholstery and all interior linings underline the light, sophisticated and sustainability-oriented atmosphere within the passenger compartment.

The instrument panel is deliberately padded only where technical components have to be appropriately covered, thus making an important contribution to passenger safety in the event of a collision. The instrument cluster played a fundamental role right from the start in the design process, serving as the starting point for all surfaces within the interior and thus creating a particularly powerful rendition of that driver orientation typical of BMW.

Innovative light technology: providing clear signals to the outside and offering soothing ambient illumination inside in a unique symbiosis.
LED lights at both the front and rear end of BMW EfficientDynamics Concept provide an innovative combination of the symbols typical of the brand and clear design language oriented towards trendsetting technology. The distinctive look of the dual round headlights characteristic of a BMW is emphasized in particular by the use of LED technology. The rear lights are integrated also in their function into the design of the entire rear section, forming part of the rear air deflector and thus merging completely into the rear contour.

Extremely flat and compact, the rear lights are made up of innovative LED units forming a smooth and consistent red surface when not in use. Only when used do the respective light chambers take on the appropriate color such as yellow on the direction indicators. This innovative light technology also provides an intense symbiosis of the exterior and interior, again promoting and further refining the driving experience.

This is also why the ambient illumination of the interior comes with new features and qualities, the light sources within the passenger compartment being fed from the positioning lights at the side, the rear lights and the brake lights, thus changing the atmosphere created by the lights within the car as a function of driving conditions.

The optical impression conveyed by BMW EfficientDynamics Concept also results in other areas from the symbiosis of the exterior and interior, eliminating the conventional barriers between the two. The lines within the interior, for example, continue on to the innovative design of the engine compartment lid, while in its shape the third brake light positioned higher up on the car follows the structure of the glass roof and tapers to the outside where the roofline moves down gently to the rear.

Overhead doors for convenient access to all seats.
The doors on BMW EfficientDynamics Concept open up like bird's wings, turning on pivots in the front roof column at the level of the side direction indicators. Since the car has no B-pillars, the large door cutouts ensure convenient entry also to the rear seats. The pivots on the doors also provide the base for the exterior mirrors, thus forming an ideal combination of function and aesthetic design. The structure of the doors is also characterized by several layers of materials on top of one another and the optical and functional symbiosis of the interior and exterior this technology is able to offer. Made up of three layers, the overall structure comprises the outer glass surface, an interim load-bearing layer, and the interior cover with its particularly smooth shapes and fl owing forms clearly visible to the passengers, layering technology again, therefore, opening up new perspectives.

The large glass surfaces extending far down on the body also provide a strong optical impression of the low seating position close to the road. And at the same time a stable sidebar ensures the body stiffness and crash safety naturally required on every vehicle. Flowing to the inside at its central point, this safety element also serves as an armrest. This interplay of the three layers also helping to minimize the weight of the car continues on the trim bar running along the door and extending out of the armrest, finally flowing into the outer door opener on its path from inside to outside.

Clear focus on the essential: 3-dimensional Head-Up Display.
Layering technology is also used on the displays in the instrument cluster and in the Head-Up Display developed to an even higher standard on BMW's new concept car. The Display now creates a powerful impression of three dimensions, at the same time providing the option to present various signals more in the front or more in the background, depending on their relevance and current driving conditions.

The Head-Up Display projects information important to the driver on to the windscreen. Indeed, innovative presentation technology even allows the superimposed presentation of several views in three dimensions, keeping, the gauge graphics visible in the background while the latest information on route guidance or warning signals from BMW Night Vision, for example, are shown in the foreground.

The sequence in which such signals appear depends on the driving mode chosen by the driver, the display technology, again depending on the driver's personal preference, enhancing a particularly sporting, a more comfort oriented, or an efficiency-based style of motoring. Through its design alone, the BMW EfficientDynamics Concept car clearly shows that highly efficient individual mobility may by all means be presented in emotional style. BMW already offers models in all vehicle segments which, compared with the competition, ensure the lowest level of fuel consumption and emissions combined with superior power and performance.

And now BMW EfficientDynamics Concept confirms BMW's commitment to offer a perfect combination in future of unique driving pleasure and optimum qualities in the responsible use of natural resources.

In the design process the need for sustainable management is borne out most clearly by the GINA (Geometry and Functions in N-fold Augmentation) concept developed by the BMW Group. In this case maximum creative freedom sets the foundation for innovative solutions challenging the conventional and meeting the requirements of the future. This makes the GINA principle particularly well-suited for developing visions for the future reflecting both the wish for emotional style and individual character as well as the quest for sustainable management and efficiency. From the dimensions of its wheels through the design of the rear lights and all the way to the configuration of the cockpit, BMW EfficientDynamics Concept therefore boasts a number of details both outside and inside which, going far beyond conventional solutions, open up a new approach to maximum efficiency and that Dynamic ability typical of BMW.

Forward-looking energy management adjusting to individual requirements.
With the individual system components on board BMW EfficientDynamics Concept being networked with one another, conditions are perfect for implementing a forward-looking system of energy management using information gathered by the sensors of the driver assistance units fitted in the car. Data provided, for example, by the rain sensor or Active Cruise Control with its Stop & Go function as well as by the navigation system, and subsequently evaluated by the central control unit, offers an overview of current and upcoming driving conditions. Then, evaluating such data, the on-board computer is able to forecast driving conditions on the stretch of road immediately ahead, such calculations serving to prepare the car for upcoming requirements and make efficient use of the energy available through optimum operation of all systems.

Should the high-performance central computer establish, for example, that the driver is about to take the motorway, the power used for running the cooling system is reduced for a certain period in advance, on the assumption that the short increase in coolant temperature resulting from such an energy-saving measure will quickly be set off by the higher speed of the car on the motorway. Another example of such pre-conditioning is the regeneration of energy from the air conditioning, from Electronic Power Steering and the Brake Assistant.

Bmw 7 ActiveHybrid (2010)

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.
