If you thought BMW was about to bring environmentally responsible driving to the average Joe, then you might be a touch disappointed with the price tag slapped on the 2011 ActiveHybrid 7 models.

The vehicles made their North American debut at the Los Angeles International Auto Show ahead of arriving in showrooms from spring 2011. So how much will they cost? Well the base price will be $103,215 which includes destination and handling for the ActiveHybrid 7 and $107,025 for the long wheelbase ActiveHybrid 7L.

Better start saving now then.

So what do you get for your money?

Well, the ActiveHybrid 7 is a mild-hybrid application that offers a 15 per cent reduction in fuel consumption. It includes a combination of an upgraded 4.4litre twin-turbo, high precision direct injection V8 engine with a three-phase synchronous 15kW electric motor, which is supplied by a compact, 400Wh lithium-ion battery. This gives the BMW ActiveHybrid 7 a combined output of 455hp and a maximum torque of 516lb-ft according to preliminary figures.

 

The BMW ActiveHybrid X6 is the world’s first Sports Activity Coupé with full hybrid drive offering a driving experience quite unique both in the segment of BMW X models and in the hybrid segment as a whole. Through its combination of a V8 gasoline engine and electric drive, the BMW ActiveHybrid X6 offers a significant increase in dynamic performance together with a reduction of fuel consumption and emissions by approximately 20 per cent. This joint enhancement of driving pleasure and efficiency clearly proves that the BMW ActiveHybrid X6 is a typical BMW in the hybrid segment.

BMW ActiveHybrid technology offers the driver three significant options: to drive under electric power alone, to use the power of the combustion engine, or to benefit form the combination of both drive modes. Driving completely free of CO2 in the electric mode is possible up to a speed of 60 km/h or 37 mph. The combustion engine then cuts in as required (as a function of load conditions) and is automatically switched off when driving in overrun at a speed of less than 65 km/h or 40 mph.

The drive system featured in the BMW ActiveHybrid X6 consists of a 300 kW/407 hp V8 power unit with BMW TwinPower Turbo Technology and two electric motors developing 67 kW/91 hp and, respectively, 63 kW/86 hp. Maximum system output is 357 kW/485 hp, peak torque is 780 Newton-meters/575 lb-ft. This makes the BMW ActiveHybrid X6 the most powerful hybrid vehicle in the world.

Through its unique balance of performance and fuel economy the BMW ActiveHybrid X6 sets new standards both in the hybrid vehicle segment and in the overall market of BMW X models. Acceleration from a standstill to 100 km/h comes in 5.6 seconds. Average fuel consumption in the EU5 test cycle is 9.9 liters/100 km (equivalent to 28.5 mpg imp), the CO2 emission rating is 231 grams/kilometer.

Integration of the two electric motors in the two-mode active transmission of the BMW ActiveHybrid X6 allows two self-sufficient modes of operation. One mode is for setting off in particularly dynamic style and for driving at low speeds, the second is for driving at a higher speeds under optimum conditions. This ensures all the benefits of BMW ActiveHybrid technology, with maximum efficiency under all loads and at all speeds. At the same time the seven-speed automatic transmission provided by the electric motors together with three planetary gearsets and four multiple-plate clutches ensures all the supreme driving behaviour, smoothness and performance so typical of BMW.

When applying the brakes or taking back the gas pedal kinetic energy is converted into electrical energy and stored in the high-performance battery. To provide this benefit either one or both electric motors act as a generator, depending on driving conditions. The recuperation efficiency and output achieved by the system is 25 times greater than with Brake Energy Regeneration featured so far in BMW’s production models.

Electrical energy is stored in an NiMH high-performance battery with a capacity of 2.4 kWh. The temperature of the high-voltage battery is controlled as required and with maximum efficiency by liquid cooling interacting with the air conditioning and an external heat exchanger.

The central electronic control unit ensures appropriate interaction of the combustion engine and electric drive crucial to the outstanding efficiency and unique qualities of the BMW ActiveHybrid X6. It converts high-voltage direct current from the high-performance battery into three-phase alternating current for the two electric motors in the hybrid transmission. It also coordinates all functions of the hybrid system including the distribution of torque and power between the combustion engine and the electric motors as well as the selection of gears.

Over and above the electric motors, the high-performance battery also supplies electrical energy to the power-consuming items linked to the 12-volt on-board network. The BMW ActiveHybrid X6 is equipped with electromechanical power steering and an electrical climate compressor both remaining fully functional also when the combustion engine is switched off and enhancing the overall efficiency of the vehicle to an even higher standard through their on-demand consumption and uptake of energy.

While braking the generator builds up stopping forces in the electric motors acting efficiently on all four wheels and precisely coordinated with the hydraulic brake effect in accordance with the driver’s stopping and deceleration requirements. This provides not only optimum stopping power, but also the brake feeling so typical of BMW under all driving conditions including the all-electric mode. A further point is that like the BMW X6, the BMW ActiveHybrid X6 comes with Dynamic Stability control incorporating an enhanced range of functions such as Dry Braking and Fading Compensation as well as an electromechanical and hydraulic parking brake complete with an Auto-Hold function.

In its driving behavior and motoring comfort, the BMW ActiveHybrid X6 offers all the standards provided by BMW’s latest X models, without the slightest difference between the electrical and the combustion drive mode. Intelligent xDrive all-wheel-drive technology with permanent, variable power distribution front-to-rear enhances the unique driving dynamics of the vehicle to an even higher standard.

The current operating mode and function of the drive system is clearly presented by appropriate displays in the instrument cluster and in the Control Display itself. The charge level of the high-performance battery at the disposal of the driver and the current operating mode are shown by appropriate gauges beneath the rev counter. Being informed of the power uptake when driving in the electric mode, the driver may if he wish maintain that mode longer in the interest of extra efficiency. And if he wishes the driver may also call up information on the current flow of energy in the Control Display.

The particularly prominent Powerdome on the engine lid gives the BMW ActiveHybrid X6 a very distinctive look versus the ‘regular’ BMW X6 as a significant visual highlight. "ActiveHybrid" model designations on the tailgate trim bar and on the front doors, the designation "BMW ActiveHybrid" on the door entry covers on either side, 19-inch light-alloy wheels (or, as an option, 20-inch light-alloy wheels in aerodynamically optimised Streamline design), as well as exterior paintwork in exclusive Bluewater metallic for the first time on a BMW X6 serve furthermore to highlight the particular character of this unique car.

The BMW ActiveHybrid X6 combines innovative drive technology with the unique concept of a Sports Activity Coupé. The very progressive and exclusive character of this outstanding vehicle is further underlined by a particularly wide range of standard features as well as attractive options. The BMW ActiveHybrid X6 comes as standard with features such as comfort seats, automatic air conditioning, cruise control, the BMW Professional navigation system and Park Distance Control. A further important feature is the electrical opening and closing function on the tailgate. Options include an extended range of nappa leather upholstery in an exclusive Ivory White/Black colour combination complete with double blue seams, a glass sliding/vent roof, a trailer towbar, as well as the complete range of BMW ConnectedDrive including innovative driver assistance systems.

The safety features offered by the BMW ActiveHybrid X6 include frontal and side airbags, head airbags at the side, crash-activated headrests at the front, run-flat tires as well as a Tire Defect Indicator enabling the driver to monitor the pressure individually in each tire. BMW Adaptive Headlights complete with a Bending Light function supplement the bi-xenon headlights with their daytime driving lights featured as standard.

Fascinating Efficiency: The BMW ActiveHybrid X6.

BMW ActiveHybrid technology combines superior driving dynamics with equally superior efficiency pointing far into the future, brining together both of these qualities to offer a truly unique driving experience.

The world’s first Sports Activity Coupé with full hybrid drive therefore capitalizes on the options offered by combining the combustion engine and the electric motor with a standard of perfection never seen before. BMW ActiveHybrid technology offers a significant increase in driving dynamics and at the same time reduces fuel consumption by approximately 20 per cent versus a comparable vehicle powered by a combustion engine alone. The result is even greater Sheer Driving Pleasure combined with enhanced fuel economy and CO2 management providing the kind of progress to make the BMW ActiveHybrid X6 a typical BMW in the hybrid market.

The overall drive system featured in the BMW ActiveHybrid X6 consists of a 300 kW/407 hpV8 gasoline engine with BMW TwinPower Turbo Technology and two electric synchronous motors delivering 67 kW/91 hp and, respectively, 63 kW/86 hp. Maximum system output is 357 kW/485 hp, peak torque is 780 Newton-meters/575 lb-ft.

Precisely controlled interaction of the three power units optimizes the overall efficiency of the BMW ActiveHybrid X6 at all speeds, with acceleration from a standstill to 100 km/h in 5.6 seconds. Top speed of the BMW ActiveHybrid X6 is limited electronically to 236 km/h or 146 mph (250 km/h or 155 mph with the optional Sports Package, with average fuel consumption in the EU test cycle of 9.9 liters/100 km (equal to 28.5 mpg imp) and a CO2 emission rating of 231 grams per kilometer.

BMW’s first full hybrid model is able to run exclusively on electric power – and that is entirely free of CO2 – up to a speed of 60 km/h or 37 mph, with the combustion engine being activated automatically whenever required.

Ideal variation of the two drive modes for enhanced efficiency and dynamism is ensured by The two-mode active transmission provides the ideal combination of the two power modes for enhanced efficiency and dynamic performance at all times. With the two electric motors, three planetary gear-sets and four multiple-plate clutches, drive power is transmitted through a seven-gear automatic transmission operated by the driver of the BMW ActiveHybrid X6 via an electronic gear selector lever and, respectively, shift paddles on the steering wheel.

BMW’s intelligent xDrive all-wheel-drive system spreads out engine power variably between the front and rear wheels.

The electric motors receive their energy from an NiMH high-performance battery positioned beneath the floor of the luggage compartment and feeding electric power also to the car’s on-board network. Luggage compartment capacity is therefore the same as on the ‘regular’ BMW X6 with its combustion engine. When applying the brakes or taking back the gas pedal kinetic energy is converted into electrical energy and is stored in the high-performance battery. To provide this function either one or both of the electric motors acts as a generator, feeding electric power generated without the slightest increase in fuel consumption directly into the high-voltage battery. Subsequent use of this energy to provide extra drive power significantly reduces the consumption of fuel.

BMW ActiveHybrid technology raises the development of drive systems enhancing both efficiency and dynamism in one to a new, unprecedented standard, clearly confirming BMW’s superior competence in development in this area. Now the introduction of this innovative technology in such an exceptional vehicle concept adds a particularly fascinating motoring experience through the efficiency achieved in this way. Through its size, character and driving dynamics, the world’s one and only Sports Activity Coupé is particularly well-suited to combine the progressiveness and the potential of BMW ActiveHybrid technology to a standard never seen before.

Unique Efficiency Ensured by Two-mode Active Transmission.

BMW ActiveHybrid technology has been developed specifically for use in a particularly dynamic vehicle in this segment and for a broad range of practical use going far beyond city traffic as such. The big advantage, therefore, is the overall optimization of drivetrain efficiency in all speed ranges and under all conditions.

The two-mode active transmission is based on an ECVT (electric continuously variable transmission) operating in two separate modes. One mode is for setting off with particular power and for driving at low speeds, the second is for motoring at high speeds.

When setting off only one of the two electric motors is activated. Then, as soon as the driver requires more power, the second electric motor automatically activates the combustion engine and subsequently serves as a generator providing a permanent supply of electric power.

When driving steadily at a higher speed most of the power required is delivered by the combustion engine in a largely mechanical process. Here again, one of the two electric motors acts as a generator.

Together with the mechanical components, the electric motors form a joint transmission unit providing the optimum transmission ratio at all times as a function of driving conditions. The mechanical link within the two-mode active transmission is provided by three planetary gear-sets in a configuration dividing the drive power generated by the combustion engine and the two electric motors into two transmission modes and therefore ensuring a degree of variability in combining the two power sources conventional hybrid drive would not be able to provide.

The two operating modes of the electric motors are supplemented and enhanced by fixed transmission ratios providing a total of seven gears for full use of the highly efficient hybrid function throughout the vehicle’s complete range of operation and at the same time maintaining the driving performance so typical of BMW.

Conventional but unique all in one: V8 gasoline engine with BMW TwinPower Turbo Technology and High Precision Injection.

The combustion engine is a technically unique eight-cylinder featured for the first time in the BMW X6 xDrive50i. The world’s first V8 gasoline engine with two turbochargers in the V-section between the two rows of cylinders excels in particular through its smooth development of power setting in from the start and continuing in an ongoing surge throughout the entire speed range. The exceptionally spontaneous and direct response of this V8 with BMW TwinPower Turbo Technology results directly from the compact configuration of the engine allowing short manifolds as well as large cross-sections on the intake and exhaust side.

Displacing 4.4 litres, this outstanding eight-cylinder delivers maximum output of 300 kW/407 hp consistently maintained between 5,500 and 6,400 rpm. Superior torque of 600 Newton-metres/442 lb-ft is maintained all the way from 1,750 to 4 ,500 rpm, with High Precision Injection ensuring precise supply of fuel at all times.

Piezo-injectors positioned in the middle between the valves ensure a smooth, efficient and clean combustion process, the V8 naturally fulfilling both the European EU5 standard as well as the ULEV II limits in the USA.

Compared with the power unit featured in the BMW X6 xDrive50i, this new engine has been modified in numerous respects to the specific requirements of the BMW ActiveHybrid X6. The first point is that there is no starter, no alternator and belt drive for the climate compressor and hydraulic pump on the power steering. The main and low-temperature circuits in the cooling system have been modified for all-electric operation, the low-temperature circuit already serving to cool the charge air in the combustion engine being used additionally to cool the power electronics.

A specifically designed hybrid engine cover, finally, marks a clear difference versus the power unit in the BMW X6 xDrive50i.

Electric Motors For Enhanced Performance On No Extra Fuel.

When accelerating the eight-cylinder power unit of the BMW ActiveHybrid X6, joining forces with the electric motors, ensures optimum efficiency and dynamic performance. As soon as the driver requires more power the two electric motors fed by the high-voltage energy battery supply additional torque for enhanced performance. This boost effect significantly increases the overall output of the BMW ActiveHybrid X6, without any increase in fuel consumption.

While the two electric motors have almost the same output, they have been modified in their performance characteristics to meet individual requirements. The power delivered is 67 kW/91 hp and. respectively, 63 kW/86 hp, with peak torque of 260 Newton-meters/192 lb-ft and 280 Newton-meters/206 lb-ft.

The electric motors support the combustion engine effectively throughout the entire speed range, the additional electrically generated drive power serving to reduce the power output required on the combustion engine when driving steadily at a higher speed. This shift in load is perfectly controlled at all times to give the overall system enhanced efficiency and its maximum effect under practical driving conditions.

The electronic control unit is also able to provide a consistent, ongoing surge of power, maximum power being generated when shifting gears through the so-called response boost effect. When kicking down the accelerator for maximum acceleration, the control unit generates stationary boost right from the start in the initial downshift phase, interaction of response boost and stationary boost ensuring a very spontaneous and direct response to every movement of the gas pedal.

Maximum system output is 357 kW/485 hp, with peak torque of 780 Newton-meters/575 lb-ft. This makes the BMW ActiveHybrid X6 the most powerful hybrid vehicle in the world, with acceleration from a standstill to 100 km/h in just 5.6 seconds and top speed is limited electronically to 236 km/h or 146 mph (or, respectively, 250 km/h or 155 mph with the optional Sports Package).

The unique position of BMW ActiveHybrid X6 within the BMW X segment as a whole follows very clearly and convincingly from the comparison of these performance figures, on the one hand, with the vehicle’s fuel consumption and emission ratings, on the other. The BMW ActiveHybrid X6 combines its supreme dynamism with equally fascinating efficiency, with fuel average fuel consumption in the EU test cycle of just 9.9 ltr/100 km (equal to 28.5 mpg imp) and a CO2 rating of 231 grams per kilometer.

All-electrical Driving Mode Reducing Emissions to Zero.

With its combination of two-mode active transmission and high-performance battery, the BMW ActiveHybrid X6 is able to run on its electric motors alone. This makes it a zero emission vehicle under such conditions, fulfilling even the strictest requirements foreseen for the future and ensuring the highest conceivable level of mobility.

The BMW ActiveHybrid X6 may run on electric power alone regardless of the ambient temperature, minimum operating temperatures being required only for the engine coolant, transmission fluid and high-voltage battery. A further requirement is that the high-performance battery is adequately charged.

Top Speed in the Electric Mode is 60 km/h or 37 mph, Maximum Range is 1.6 miles.

While driving electrically, the BMW ActiveHybrid X6 retains all its safety and comfort functions. The brakes remain fully operative thanks to electronic vacuum supply, not requiring the combustion engine to develop their full effect. The same applies to the EPS Electronic Power Steering, with steering assistance being generated as required and with maximum efficiency by an electric motor.

Even the air conditioning remains fully available without any restrictions,running efficiently on an electrical climate compressor. And since the high-performance battery supplies electric power to the complete 12-volt on-board network through a voltage converter regardless of the driving mode, all other power-consuming items such as the lights and the on-board entertainment system remain fully functional at their usual, consistent level.

Recuperation: Electric Power Generated Without Additional Fuel Consumption.

The BMW ActiveHybrid X6 features an enhanced version of Brake Energy Regeneration already used in BMW’s current models running on a combustion engine alone, generating the electric power saved in the high-performance battery. In this case the electric motors act as generators in overrun and when applying the brakes in order to feed electric power into the high-voltage battery unit, again in the interest of maximum efficiency.

This uses energy otherwise simply lost in conventional vehicles as heat escaping through the brakes – and depending on road speed, one or both of the electric motors may perform this function.

The power delivered by the generator is approximately 50 kW, about 25 times as much as the power provided so far by Brake Energy Regeneration.

Generator Delivering Electrical Brake Power.

In the generator mode the two electric motors supply a lot of the energy required to slow down the vehicle whenever necessary. Indeed, the stopping power generated in this way is up to 3 meters/sec or, respectively, 0.3 g in a purely recuperative process, significantly reducing the load acting on the mechanical brake system.

Sensotronic Brake Actuation (SBA) in the BMW Active Hybrid X6 may be used at any time without a direct mechanical connection between the brake pedal and the hydraulic circuit. Pedal movement is recorded by sensors and split up by a control unit into brake power generated in a regenerating and in a hydraulic process. At the same time an integrated pedal force simulator generates the usual brake feeling for the driver as an additional factor in this brake-by-wire solution.

The active brake servo builds up brake pressure with electrical control according to the signals emitted by the control unit. To ensure brake power assistance also in the all-electric mode, the BMW ActiveHybrid X6 comes furthermore with an electrical under-pressure pump replacing the vacuum pressure in the intake system of the combustion engine on a conventional vehicle. A mechanical fallback function, in turn, guarantees full operation of the brake system in the event of a failure or deficiency in the electrical system, in which case the stopping power required is generated by the hydraulic system alone, like on a conventional vehicle.

The primary task of the SBA system is to split up the brake power required by the driver into a regenerating and a hydraulic brake factor. Via the xDrive powertrain, the hybrid system in the BMW ActiveHybrid X6 is able to transmit brake forces to all four wheels generated by the stopping power of the recuperative electric motors. And whenever the stopping power required exceeds the level of 3 meters/sec, the control unit builds up additional brake force through the mechanical brake by means of the active brake servo.

In braking situations critical to driving stability the control unit receives additional signals from the DSC Dynamic Stability Control, intervening in the brakes and engine management to keep the vehicle safely on course. This ensures safe braking maneuverer under all conditions, with all driving stability systems developing their complete effect when required regardless of whether the stopping power needed is generated electrically or hydraulically.

A further point is that all driving stability systems are tailored in their operation to the dynamic character of the Sports Activity Coupé also on the BMW ActiveHybrid X6. DTC Dynamic Traction Control selected at the touch of a button, for example, provides maximum traction and drive power on loose surfaces such as snow or sand thanks to its higher slip thresholds. And with the DTC mode activated, the driver may opt for a particularly sporting style of motoring all the way to a controlled power slide in bends.

The sports-oriented driving behaviour of the BMW ActiveHybrid X6 is also attributable to xDrive all-wheel-drive technology. Permanent all-wheel drive with electronically controlled, variable distribution of drive power front-to-rear gives the BMW ActiveHybrid X6, like all BMW X models, not only superior traction, but also enhanced driving dynamics.

BMW xDrive qualifies as an intelligent all-wheel-drive system in particular through the smooth division of drive power ensured by a power divider with an electronically controlled multiple-plate clutch feeding the appropriate level of power to the right axle with optimum wheel contact and grip on the road.

Under normal conditions BMW xDrive spreads out drive power to the front and rear axle in a 40:60 split, sensors consistently measuring wheel slip both front and rear. The system is able to vary the balance of drive power within fractions of a second, BMW xDrive, unlike conventional all-wheel-drive systems, thus looking ahead and not only responding when a wheel is already spinning.

Benefiting from these abilities, BMW xDrive raises the driving dynamics of the BMW ActiveHybrid X6 to an even higher level by recognizing even the slightest tendency to over- or under-steer right from the start and taking appropriate counter-action.

EPS Electronic Power Steering for Even Greater Driving Comfort.

The BMW ActiveHybrid X6 is the first BMW X model to feature EPS Electronic Power Steering. This allows active steering assistance both when driving with the combustion engine and in the all-electric mode.

EPS provides optimum steering assistance under all conditions to give the driver that special feeling so typical of the BMW brand. Another advantage is the further reduction of fuel consumption, EPS significantly reducing the energy required for steering assistance compared with conventional, hydraulic power steering, since Electronic Power Steering only becomes active when steering assistance is actually required or desired by the driver. So when driving straight ahead in a straight line, for example, the electric motor does not consume any energy whatsoever.

Electronic Power Steering on the BMW ActiveHybrid X6 comes complete with fully integrated speed-related Servotronic steering assistance, the reduction of assistance at high speeds ensuring not only safe directional stability but also extremely precise steering behavior in bends as well as the safe feeling at high speeds again so characteristic of a BMW. At low speeds, on the other hand, for example when parking, extra power assistance significantly reduces the steering forces required.

Liquid Ccooling For Even Greater Performance on the High-performance Battery.

The high-voltage battery featured in the BMW ActiveHybrid X6 comes in nickel-metal hybrid technology (NiMH). Capacity is 2.4 kWh, with 1.4 kWh available actively for practical use. Maximum output, in turn, is 57 kW, with the battery’s control unit permanently determining the output level currently available as well as the charge status of the battery.

The high-performance battery comes with its own liquid cooling system incorporating a heat exchanger to cool the battery through the flow of air from the outside and, additionally, through the cooling circuit in the air conditioning. These two circuits are activated either individually or in combination with one another, depending on current requirements, the control unit selecting the most effective and efficient cooling option as a function of ambient temperature and the temperature of the high-voltage storage unit.

Cooling by the air conditioning is activated by an appropriate switch valve, with the electrical climate compressor being switched on automatically whenever required. The interior and the high-voltage battery being cooled separately of one another, cooling is far more efficient than with a system using air cooling only, raising the energy storage medium to a far higher level of performance and retaining the hybrid functions longer in extreme weather and whenever the driver prefers a very sporting style of motoring. Ultimately, this gives BMW ActiveHybrid X6 an outstanding potential in driving dynamics far superior to other hybrid vehicles in the market.

Intelligent Energy Management And Integral Safety Concept.

Power electronics developed especially for BMW ActiveHybrid technology ensures energy management on board the BMW ActiveHybrid X6 both very efficient and flexible in use. The electronic control system consistently controls the distribution of energy as a function of ambient conditions, the status of the vehicle, and the demands made by the driver. The most important incoming and control factor for the operating strategy chosen is the charge status of the high-performance battery saving the electrical energy generated through recuperation.

The BMW ActiveHybrid X6 naturally complies in full with the integral safety concepts developed for hybrid vehicles by BMW. With central control functions being integrated both in the power electronics and the energy battery, the system has the ideal starting point for fulfilling all kinds of international crash test standards as well as the demanding internal standards of the BMW Group, in particular guaranteeing the highest level of operating safety on all components in the high-voltage on-board network.

Some of the features of this safety concept are the different colors of cables to avoid any confusion, the presentation of clear safety warnings and the all-round cover on the entire system using extra-large insulation panels and newly developed connectors.

The high-voltage battery is housed in a high load-resistant steel casing and is fitted firmly inside the car, just above the rear axle at an extremely safe point for the event of a collision. The status of the storage modules is constantly supervised by integrated safety electronics, the driver being informed immediately of any malfunction and, wherever necessary, the entire system being automatically discharged and deactivated.

In the event of a collision, the system is switched off automatically within fractions of a second, the car’s central safety electronics assessing the severity of an accident and ensuring a safe operating mode as a function of current, individual requirements.

Special Hybrid Drive Auto Start Stop Function.

In city traffic the BMW ActiveHybrid X6 can be run in the all-electric mode without using the combustion engine. A further advantage is that the vehicle comes with a new generation of Auto Start Stop technology featured here for the first time. Tailored specifically to the requirements of a hybrid car, this new Auto Start Stop function allows a much higher standard of comfort and is available more often than the conventional system. Automatic deactivation of the combustion engine at a road junction or at the traffic lights does not in any way impair the driving experience, just as the V8 power unit will start again immediately as soon as the driver presses down the gas pedal.

BMW ActiveHybrid X6 provides the Auto Start Stop function consistently at all outside temperatures, no matter how cold or how hot.

As long as the engine is switched off, the electric climate compressor automatically maintains the climate and temperature desired within the passenger compartment. All other electrically operated functions are also maintained, with the on-board network being consistently supplied with power from the high-voltage storage unit. The only way to deactivate the special hybrid Auto Start Stop function is by choosing the manual gearshift mode on the automatic transmission.

Additional displays informing the driver of the operating status and efficiency of the hybrid system.

Operation of the hybrid system and current operating conditions are presented clearly and understandably in the displays. The most important information is shown in the central instrument cluster, clearly separated according to the various operating modes. Further information and technical explanations, in turn, are shown in the Info Display in the center console. 

The drive displays are split up into a conventional rev counter for the combustion engine and special displays for electric drive in the lower part of the instrument cluster. Clear visual presentation of these functions shows the driver that the vehicle is ready to go. The electric drive displays relevant to the driver are the charge status of the high-voltage storage unit, the recuperation display, the support provided by the electric motors when accelerating through their boost function, as well as the driving stages in the all-electric mode. In the Control Display this information is supplemented by additional data on current operating conditions and the current flow of energy.

Specific Set-up of The Suspension and the Lightweight Brakes.

The chassis and suspension of the BMW Active Hybrid X6 is largely the same as the technology already featured on the BMW X6 xDrive50i. The front axle is a double track arm configuration ensuring excellent driving dynamics, superior motoring comfort and smooth directional stability. The Integral IV rear axle has been modified to reflect the specific characteristics of the hybrid model in terms of weight distribution and drive power, guaranteeing absolute supremacy on the road also ensured by self-levelling with air suspension providing a consistent ride height also when carrying a heavy load.

Lightweight brakes decelerate the BMW ActiveHybrid X6 by means of swing-calliper brake discs incorporating covers and pistons made of aluminum. Brake disc diameter is 385 millimeters or 15.2′ up front and 345 millimeters or 13.6′ at the rear. The entire brake system ensures a high standard of comfort in applying the brakes and extreme resistance to fading.

Consistent lightweight engineering serves to reduce unsprung masses and improve the vehicle’s driving comfort and agility.

Very attractive 19-inch light-alloy rims in V-spoke design come as standard, and 20-inch light-alloy rims in aerodynamically optimised Streamline design have been developed exclusively for the BMW ActiveHybrid X6 as an option. In each case the tyres are runflat tyres enabling the driver to continue to the workshop even after a complete loss of pressure. And it almost goes without saying that the BMW ActiveHybrid X6 comes as standard with a Tire Defect Indicator incorporating individual tyre pressure control.

Body-shell and Safety: Intelligent Lightweight Construction, Optimized Occupant Safety.

Intelligent lightweight construction and a special structure for maximum solidity also characterize the body-shell of the BMW ActiveHybrid X6. Apart from frontal and hip thorax airbags, curtain head airbags at the side are also standard within the interior.

The BMW ActiveHybrid X6 comes with three-point inertia-reel seat belts on all seats featuring belt force limiters and belt latch tensioner on the front seats. To protect the occupants from cervical spine injury in the event of a collision at the rear, the front seats feature crash-activated headrests, the rear seats come as standard with ISOFIX child seat fastenings.

All restraint systems are masterminded by central safety electronics, rollover sensors serving to activate the curtain airbags and belt latch tensioners in the event of an impending rollover.

Featured as standard, dual bi-xenon headlights not only ensure optimum illumination of the road ahead in the dark, but also provide a daytime light function through their corona rings. The BMW ActiveHybrid X6 furthermore comes as standard with a light and rain sensor automatically controlling the vehicle’s lights and screen-wipers as required. Additional comfort at night is provided by the High Beam Assistant featured as part of BMW ConnectedDrive.

Another feature available as an option is Adaptive Headlights following the road ahead in providing exact the right illumination. This option comes complete with Bending Lights and variable light distribution broadening the light beam to provide a wider range of vision as a function of road speed. As an option, finally, information relevant to the driver may be projected on to the windscreen via the Head-Up Display in a particularly ergonomic position.

Over and above safety-relevant driver assistance systems, BMW ConnectedDrive offers a range of further services enhancing driver comfort and allowing optimized use of the infotainment systems in the BMW ActiveHybrid X6. This range of mobility services comprises features such as BMW Assist with a telephone enquiry service and an Enhanced Emergency Call function including automatic detection of the vehicle’s location, BMW Online, BMW TeleServices as well as unrestricted use of the Internet in the vehicle.

The BMW ActiveHybrid X6: Sports Activity Coupé of the Highest Standard, BMW ActiveHybrid With Maximum Efficiency.

The BMW ActiveHybrid X6 combines an innovative vehicle concept with cutting-edge drivetrain technology to provide a truly unique driving experience. The enhancement of both dynamic performance and all-round efficiency gives BMW’s Sports Activity Coupé, as unique as it already is, additional fascination and appeal, BMW ActiveHybrid technology achieving a supreme level of efficiency in this outstanding model, confirming BMW’s great competence in the area of drivetrain development.

From outside the BMW ActiveHybrid X6 differs through only a few details from the "regular" models with their conventional drivetrain technology. With its elegant and dynamically flowing roofline and features typical of a BMW X model, the Sports Activity Coupé offers a uniquely sporting rendition of this very special vehicle with its unprecedented character also in the full hybrid variant.

The space available and driving comfort likewise reflect the supreme standard this dynamic four-seater already offers in the versions already available. And apart from the special hybrid displays in the instrument cluster, door entry trim covers proudly bearing the designation "ActiveHybrid" on the driver’s and front passenger’s doors add a particular highlight and sign of distinction.

Particularly the very impressive Powerdome on the engine compartment lid ensures a clear distinction of this very special vehicle from outside, "ActiveHybrid" model designations on the tailgate trim bar and the front doors as well as body paint in exclusive Bluewater metallic offered for the first time on a BMW X6 likewise alluding to the very special character of this very special vehicle. 

While some of us here at ABG HQ are major fans of BMW’s diesel engines, we were disappointed when BMW opted to enter the U.S. market only with the twin turbo 3.0-liter six cylinder diesel. As fantastic an engine as that is, the 2.0-liter four cylinder is also plenty strong and yields even better fuel efficiency. At an event at BMW’s North American headquarters this week, VP engineering Tom Baloga told the audience that BMW would introduce the four-cylinder diesel to the U.S. lineup now that tougher fuel economy standards have been imposed. In keeping with BMW’s performance image, we will get the more powerful variants, likely the dual turbo, 204 hp version used in the 123d rather than the super-high-efficiency versions. Even with that engine, we averaged 37 mpg in the 123d last year. BMW plans to clean up the four cylinder diesel with a lean NOx trap like VW uses for the Jetta and Golf TDI rather than a more expensive and complex urea injection system. The four cylinder will most likely go into the 3 and maybe 1 series cars with the six being reserved for larger cars like the 5, 7 and X5.

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.
