BMW 7 ActiveHybrid

Bmw 7series Activehybrid

Bmw 7series Activehybrid

On the heels of the BMW X6 ActiveHybrid, BMW announced the production version of the all-new BMW 7 ActiveHybrid, which will also premiere at the 2009 Frankfurt Auto Show (IAA). The BMW 7 ActiveHybrid will reach America shores in Spring, 2010. Based on the newest BMW 7-Series, this unique car sets new standards for performance and efficiency in the premium luxury class.

This symbiosis of an upgraded twin-turbo, High Precision Direct Injection, V8 engine with a 3-phase synchronous elec¬tric motor gives the BMW 7 ActiveHybrid a combined output of 455 hp and maximum torque of 516 lb-ft (preliminary figures). Power is transmitted via an 8-speed automatic transmission with the electric motor positioned between the engine and the torque converter. The electric motor receives its supply of energy from a lithium-ion battery developed specifically for use in this automobile.

Precisely controlled interaction of both power sources serves to maximize the efficiency and dynamic performance of the BMW 7 ActiveHybrid. The result is a unique driving experience that demonstrates the performance capabilities of modern hybrid technology. The BMW 7 ActiveHybrid accelerates to 60 mph in 4.8 seconds (preliminary), while delivering fuel economy approximately 15% better than the 750i. Official EPA ratings will be available closer to the US market launch.

// // BMW ActiveHybrid technology also provides new features that promote efficiency while preserving comfort. As an example, the BMW 7 ActiveHybrid is the first BMW with automatic transmission to feature Auto Start Stop to maximize efficiency by avoiding engine idling when stopped. Another advantage is that the air conditioning and ventilation system remains fully operational when using Auto Start Stop. In this case, power is supplied directly through the 120-volt on-board network powered by the lithium-ion battery.

Special displays in the instrument cluster and the Central Display inform the passengers of the degree of efficiency and the current operating status of the hybrid components. The ActiveHybrid 7 is distinguished from the 750i by aerodynamically-tuned ten-spoke 19-inch light-alloy Aero wheels, and model designations on the trunk lid, C-pillars, and on the door cutouts. The BMW 7 ActiveHybrid is also available in Bluewater Metallic exterior paintwork.

Like existing BMW 7-Series models, BMW’s first luxury sedan with ActiveHybrid technology will enter the market in two body variants. The extended version of BMW 7 ActiveHybrid has a wheelbase increased by 5.5″, all of which is devoted to the enhanced comfort of rear-seat passengers. Both models are available with a wide range of options from the portfolio of equipment and accessories offered on the BMW 7-Series, enabling the tailoring of the ActiveHybrid 7 to individual tastes and requirements.

BMW ActiveHybrid: A key element of the BMW EfficientDynamics philosophy.

The BMW 7 ActiveHybrid takes an innovative approach to ensure outstanding efficiency in this segment. At the same time this unique sport sedan offers dynamic driving characteristics at a level that one would expect from The Ultimate Driving Machine. BMW ActiveHybrid is an important element within the BMW EfficientDynamics philosophy meant to offer technologies able to significantly reduce fuel consumption and emissions on every new model while enhancing driving performance.

BMW uses hybrid technology because it can make an effective contribution to the reduction of fuel consumption and emissions. As a rule, the savings potential of hybrid technology increases with the power of the combustion engine interacting with the system. In the case of the BMW 7 ActiveHybrid precise coordination of the electric motor and the V8 serves to optimize the efficiency of the combustion engine under all operating conditions.

Intelligent energy management for generation, storage and use of electric power.

The ActiveHybrid concept stores energy in a compact, high-performance lithium-ion battery. The processes of charging the battery, supplying power to the electric motor, and electric ancillaries are managed by a control unit developed specifi¬cally for the BMW 7 ActiveHybrid.

Energy Regeneration: Electric power captured using no extra fuel.

BMW ActiveHybrid technology uses energy that would be normally converted into heat through the brakes, and therefore wasted in conventional cars. The BMW 7 ActiveHybrid features an enhanced version of Brake Energy Regeneration already used in some current BMW models running on a combustion engine alone. In this case the integrated electric motor acts as a generator when coasting or applying the brakes, in order to feed electric power into the battery. Brake Energy Regeneration converts some of the vehicle’s kinetic energy into electric power for the on-board network whenever the driver lifts off the accelerator or applies the brakes. On acceleration, electricity is fed back into the on-board network from the lithium-ion battery. This sequence relieves the combustion engine from the task of converting some of its fuel energy into electric current, and thus enables the engine to provide more power directly to the rear wheels. The result is better acceleration even than the 750i, despite the fact that the additional power is obtained in a way that does not require additional consumption of fuel.

When the driver requires only a small amount of brake force, the system uses only the drag of the electric generator (motor). The mechanical brakes are activated only when the driver presses down the brake pedal harder for more stopping power. Dynamic Stability Control controls the balance of electrical and mechanical braking so adeptly that the driver does not even perceive the transition from braking with electric power to braking with the mechanical brake system.

Two interconnected on-board networks for flexible management of energy.

The BMW 7 ActiveHybrid features both a conventional 12-volt on-board network fed by an absorbent glass mat (AGM) battery and an additional battery featuring lithium-ion technology operating at 120-volts. The lithium-ion battery supplies power to the electric motor as required and serves to start the engine. Electric power generated by Brake Energy Regeneration is fed into both on-board networks. The air conditioner compressor on BMW 7 ActiveHybrid is integrated in the 120-volt network. All other electrically operated functions of the car are supplied by the 12-volt network. The two on-board networks are connected by a voltage converter featuring flexible energy management. Both batteries are charged and maintained through Brake Energy Regeneration. The 12-volt battery is fed with energy from the high-voltage network.

Cutting-edge battery technology: lithium-ion with superior capacity and multi-cycle operating strength.

BMW found that lithium-ion battery technology offers sufficient energy storage capability while taking up minimal space. The result is that the BMW 7 ActiveHybrid gives up almost no luggage capacity to its conventional siblings (750i and 750Li), because the 120-volt battery is small enough to be mounted underneath the trunk floor. Furthermore, the weight penalty incurred by this battery is minimal, meaning less energy is consumed to carry it. Using this technology enables the ActiveHybrid 7 to maximize storage capacity and acceleration in the hybrid luxury sedan segment. It is the fastest-accelerating hybrid sedan in the world.

The useful energy provided by this high-performance battery is 400 watt-hours. The battery itself is comprised of 35 cells and an integrated control unit which continuously analyzes the charge level and ensures appropriate dependability under all conditions. Despite its high level of performance, the lithium-ion battery measures just 14.6 x 8.7 x 9.1 inches (37 x 22 x 23 centimeters) and weighs a mere 59.5 lb or 27 kg.

Hence, it is only slightly larger than a conventional car battery and is housed conveniently in the trunk floor between the wheel arches of BMW 7 ActiveHybrid, safely surrounded by a high-strength special casing. This location provides protection for the battery and helps to preserve the 7-Series’ ideal 50-50 weight distribution. The luggage compartment with its capacity of approximately 13 cu. ft. offers adequate space for four 46-inch golf bags.

Twin-turbocharged V8 gasoline engine with High Precision Direct Injection.

The combustion engine is the innovative reverse-flow V8 introduced in the BMW X6. The world’s first V8 gasoline engine with two turbochargers in the V-section between the two rows of cylinders develops power throughout the entire engine speed range. The spontaneous and direct response of this engine results from its compact configuration, which allows the shortest exhaust manifolds.

Displacing 4.4 liters, this outstanding engine delivers its maximum output of 440 hp between 5,500 and 6,000 rpm. Peak torque of 475 lb-ft is maintained from 2,000 to 4,500 rpm, with High Precision Direct Injection ensuring precise supply of fuel at all times. Piezo-injectors positioned in the combustion chambers between the valves ensure a smooth, efficient and clean combustion process. The engine fulfils the European EU5 standard as well as the ULEV II standards in the US.

Compared with the engine featured in the BMW 750i/Li, this version has been modified in numerous respects to the specific requirements of the BMW 7 ActiveHybrid. There is no starter, alternator, or belt drive for the air-conditioning compressor and hydraulic pump. The cooling system has been modified for hybrid operation. The result is remarkable power from idle. The response of the engine is enhanced by the electric motor with its additional torque. The direct response to the accelerator pedal is impressive when compared either with conventional 7-Series models or existing hybrid vehicles already in the market. Acceleration to 60 mph in 4.8 seconds (preliminary) ranks it among the fastest and most thoroughbred sports cars in the world. Top speed of BMW 7 ActiveHybrid is electronically limited to 150 mph.

Electric motor starting and supporting one of the most advanced V8s.

The three-phase synchronous electric motor featured in BMW 7 ActiveHybrid is positioned between the engine and the torque converter, and is connected to the crankshaft. Shaped like a disc, the electric motor weighs 50.7 lb (23 kg). Its compact design ensures full integration in the transmission housing.

The electric motor generates boost of approximately 20 hp and peak torque of 155 lb-ft. When operating as a generator in Brake Energy Regeneration, the electric motor produces approximately 27 hp of brake force.

In total, the BMW 7 ActiveHybrid features a maximum system output of 455 hp and peak torque of 516 lb-ft (preliminary). Normally, this level of power output would require a correspondingly high increase in fuel consumption. The BMW 7 ActiveHybrid, in contrast, combines its power with an equally impressive increase in fuel efficiency of about 15%.

8-speed automatic transmission in combination with Auto Start Stop.

To transmit the drive power developed jointly by the V8 and the electric motor, the BMW 7 ActiveHybrid features a newly developed 8-speed automatic transmission specifically tailored to the demands of hybrid technology. This high-tech transmission combines shift comfort, sportiness and efficiency at unprecedented levels.

The new 8-speed close-ratio automatic transmission uses an inno¬vative gear-set configuration providing two additional gears and a larger overall gear range than the 6-speed automatic transmission used by BMW without negative effects on size, weight, or internal efficiency. With the new transmission, the V8 engine is better able to stay in the power peak while ensuring greater overall efficiency.

Overall efficiency is further enhanced with the Auto Start Stop function. Auto Start Stop automatically switches off the combustion engine at idle, eliminating fuel consumption when stopped. Once the driver’s foot comes off the brake pedal, the engine restarts instantaneously.

Starting of the V8 engine is accomplished by the electric motor, which is supplied with power from the high-voltage battery. This enables the engine to start extremely quickly and without any vibration. The automatic transmission is maintained in a “ready-to-drive” mode by a new hydraulic pressure accumulator for the valve body of the transmission. Additionally, the engine control unit “remembers” engine crank position and uses delay-free ignition to restart the engine in less than one crank rotation. The engine is also switched off when the driver uses the Auto Hold function. The driver just has to slightly press down on the gas pedal in order to reactivate the engine.

Continuous climate control in all circumstances.

The climate control system in the BMW 7 ActiveHybrid is supplied with power directly from the high-voltage battery, thus ensuring all the usual functionality regardless of whether the engine is running.

Hence, operation of Auto Start Stop does not compromise the infotainment or climate system operation. The desired interior temperatures are maintained consistently, regardless of how frequently or for how long the engine shuts off.

The standard 4-zone automatic climate control has a parked-vehicle function activated whenever desired by remote control. This feature serves to cool down the interior in hot weather before getting into in the car. The highly efficient air conditioning system can reduce in interior tem¬perature quickly and efficiently by more than 50 degrees Fahrenheit, providing pleasant starting conditions in an appropriately cool and pleasant passenger compartment. By running on pure electric power, the air conditioner compressor begins cooling the car more quickly than in a conventional system.

Efficiency made visible: special display concept.

Featuring Black Panel technology, the instrument cluster in the BMW 7 ActiveHybrid is supplemented by an energy flow display in the lower section of the tachometer, a blue arrow shows the current status of Brake Energy Regeneration. When accelerating, an additional graphic display illustrates the boost effect generated by the electric motor.

Using the iDrive control system in the Central Display, the driver is able to see a detailed view of the interaction between the V8 engine and electric motor. Beyond the current charge level of the lithium-ion battery, this display also shows the real-time flow of energy. As an alternative to this graphic display, the system can analyze the current efficiency. In this case a bar graph, which is updated every minute, shows the efficiency levels achieved by the hybrid components during the last fifteen minutes.

Cutting-edge suspension technology for maximum control and comfort.

When the new BMW 7-Series was introduced in 2009, it set new standards for comfort and driving dynamics. The double-wishbone front suspension and an enhanced Integral-V rear suspension provide the ActiveHybrid 7 with the ride comfort one would expect of a BMW sport-luxury sedan with the handling and control of a sports car.

The long-wheelbase version of BMW 7 ActiveHybrid includes self-leveling rear suspension. Both models are fitted with BMW’s vehicle speed-variable Servotronic power steering as well as Driving Dynamics Control. The driver is able to choose the preferred shock absorber setting, the appropriate operation of Dynamic Stability Control, the shift character of the automatic transmission, as well as the throttle response and Servotronic steering assist.

The brake system on the BMW 7 ActiveHybrid provides excellent stopping power in every situation. Inner-vented discs and floating calipers front and rear guarantee resistance to fade. The ActiveHybrid 7 comes standard with 19-inch light-alloy rims in an aerodynamically optimized ten-spoke Aero turbine wheel design, unique to this model. Likewise, runflat tires measuring 245/45 R19 front and 275/40 R19 rear enable the driver to continue even after a complete loss of pressure at a speed of up to 50 mph for up to 150 miles. As an added measure of security, the Tire Pressure Monitor will warn the driver if ever the pressure in any of the tires drops more than 20 percent.

ActiveHybrid safety systems.

The safety concept for the car’s hybrid components is comprehensive. All components in the high-voltage system feature full insulation and special plug connectors. The lithium-ion battery is protected by a high-strength steel housing and is positioned between the wheel wells in the luggage compartment, and has already been subjected to a wide range of crash tests. Last but not least, the entire high-voltage system is automatically switched off within a fraction of a second in case of a malfunction or collision.

Best of Hybrid: flexible development for optimized concepts on each model.

The hybrid components featured in BMW 7 ActiveHybrid were developed jointly by BMW and Daimler in a cooperation project seeking to develop and test components for hybrid drive in luxury performance cars. Apart from the electric motor and the lithium-ion battery, this joint venture also served to develop the power electronics for the high-voltage network featured in the BMW 7 ActiveHybrid.

Each manufacturer subsequently integrated the hybrid components into the respective model in accordance with individual, brand-specific requirements. One of the unique characteristics of the BMW 7 ActiveHybrid is exemplified by the combination of an electric motor with a V8 engine.

BMW ActiveHybrid is based on a modular principle which, following the Best of Hybrid strategy, ensures perfect integration of the optimum component in vari¬ous vehicle concepts. Hence, the mild hybrid concept of the BMW 7 ActiveHybrid is tailored ideally to the specific requirements of this model as is the full hybrid concept for BMW X6 ActiveHybrid, which will arrive at BMW Centers in late 2009.

BMW X6 ActiveHybrid

BMW X6 Activehybrid

BMW X6 Activehybrid

BMW announced the production version of the BMW X6 ActiveHybrid. The BMW X6 ActiveHybrid makes its world premiere at the 2009 Frankfurt Motor Show (IAA) and will reach US BMW Centers in fourth-quarter 2009. ActiveHybrid technology provides a glimpse into the future, achieving outstanding driving dynamics with equally impressive efficiency. It melds both of these qualities to offer a truly unique driving experience. The world’s first Sports Activity Coupe with full hybrid drive capitalizes on the options offered by combining the combustion engine with electric motors to create a powertrain with new levels dynamic performance and efficiency.

BMW ActiveHybrid technology offers a significant increase in driving dynamics and at the same time reduces fuel consumption by approximately 20 percent versus a comparable vehicle powered by a combustion engine alone. The result is even greater driving pleasure combined with enhanced fuel economy and CO2 management providing the kind of progress to make the BMW X6 ActiveHybrid a genuine BMW in the hybrid market.

The overall drive system featured in the BMW X6 ActiveHybrid consists of a 400 hp twin-turbocharged V8 gasoline engine and two electric synchronous motors delivering 91 hp and 86 hp, respectively. Maximum system output is 480 hp, and peak torque reaches 575 lb-ft.

// // Precisely controlled interaction of the three power units optimizes the overall efficiency of the BMW X6 ActiveHybrid at all speeds, with acceleration from a standstill to 60 mph in 5.4 seconds. Top speed of the BMW X6 ActiveHybrid is limited electronically to 130 mph, with average fuel consumption in the EU test cycle improved by roughly 20%, and a CO2 emission rating of 231 grams per kilometer. EPA ratings will be available closer to the market introduction.

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 37 mph (60 km/h), with the combustion engine being activated automatically whenever required.

These performance figures are made possible by utilizing a two-mode active transmission. The ideal combination of the two power modes can be controlled for enhanced efficiency and dynamic performance in any driving condition. With the two electric motors, three planetary gearsets and four multi-plate clutches, drive power is transmitted through a 7-speed automatic transmission. As would be expected in a BMW, the driver can operate the transmission manually. BMW’s lauded xDrive all-wheel-drive system distributes the power between the front and rear axles.

The electric motors receive their energy from an NiMH high-performance battery pack positioned beneath the floor of the luggage compartment. This battery pack also feeds electric power to the vehicle’s on-board network. Luggage compartment capacity is therefore the same as on the original BMW X6. On brake application and/or on deceleration, kinetic energy is converted into electrical energy and is stored in the battery pack. To provide this function either one or both of the electric motors act as a generator, feeding electric power generated back into the high-voltage battery.

Unique efficiency ensured by two-mode active transmission.

BMW ActiveHybrid technology has been developed specifically for use in a particularly dynamic vehicle and for a broad range of practical use. The big advantage, therefore, is optimization of drivetrain efficiency in all speed ranges and conditions.

The two-mode active transmission is based on an ECVT (electric continuously variable transmission) operating in two separate modes. One mode is for stop-and-go driving and low speeds, and the second is for driving at higher speeds.

From a stop and at low speeds, only one of the two electric motors is activated. As soon as the driver requires more power or increased speed, the second electric motor automatically starts the combustion engine. The second electric motor then serves as a generator to provide a supply of electric power to the vehicle systems. 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.

The mechanical components, including three planetary gearsets and the two electric motors, combine to provide for seven total effective gears. This configuration manages the power generated by the combustion engine and two electric motors in a way that maximizes driving versatility.

Twin-turbocharged V8 gasoline engine with High Precision Direct Injection.

The combustion engine is the innovative reverse-flow V8 first featured 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 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 400 hp between 5,500 and 6,400 rpm. Peak torque of 450 lb-ft is maintained from 1,750 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 X6 xDrive50i, this version has been modified in numerous respects to the specific requirements of the BMW X6 ActiveHybrid. There is no starter, alternator, or belt drive for the air-conditioning compressor and hydraulic pump. The dual-circuit cooling system has been modified for all-electric operation.

Electric motors for enhanced performance on no extra fuel.

When accelerating, the V8 engine of the BMW X6 ActiveHybrid joins forces with the electric motors to ensure optimum efficiency and dynamic performance. When the driver requires more power, the two electric motors supply additional torque for enhanced performance. This boost effect significantly increases the overall output of the vehicle, without increasing fuel consumption.

While the two electric motors have almost the same output, they have been modified in their performance characteristics to meet specific requirements. The power delivered is 91 hp and 86 hp, respectively, with peak torque values of 192 lb-ft and 206 lb-ft.

The electric motors support the combustion engine effectively throughout the entire speed range. The additional electrically-generated drive power reduces the power output required of the combustion engine when driving at steady highway speeds. Load shifts are managed to give the overall system enhanced efficiency under the full spectrum of driving conditions. During kick-down and maximum acceleration shifts, the electric motors help provide an additional boost of power.

Maximum system output is 480 hp, with peak torque of 575 lb-ft. This makes the BMW X6 ActiveHybrid the most powerful hybrid vehicle in the world, with acceleration from a standstill to 60 mph in just 5.4 seconds and top speed is limited electronically to 130 mph.

All-electrical driving mode reducing emissions to zero.

With its combination of two-mode active transmission and high-performance battery pack, the BMW X6 ActiveHybrid is able to run on its electric motors alone at low speeds. This makes it a zero-emission vehicle under such conditions.

The BMW X6 ActiveHybrid may run on electric power alone regardless of the ambient temperature, as long as minimum operating temperatures are reached for the engine coolant, transmission fluid and high-voltage battery. Top speed in the electric mode is 37 mph, maximum range is 1.6 miles.

While driving electrically, the BMW X6 ActiveHybrid retains all its safety and comfort functions. The brakes remain fully operative thanks to electric vacuum supply, and don’t require the combustion engine to develop their full effect. The same applies to the Electronic Power Steering, with steering assistance being generated on demand by an electric motor.

Even the air conditioning remains fully available without any restrictions, running efficiently on an electrically operated air-conditioning compressor. Since the battery pack supplies the electric power to the 12-volt on-board network through a voltage converter, all other systems such as the lights, infotainment, and safety systems remain fully functional.

Energy Regeneration: Electric power generated without additional fuel consumption.

The BMW X6 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 electric motors act as generators when coasting or applying the brakes in order to feed electric power into the battery pack.

This process recaptures energy which would otherwise be lost in conventional vehicles in the form of heat escaping through the brakes. Depending on road speed, one or both of the electric motors may perform the regeneration function.

The power delivered by the generator is approximately 50 kW, about 25 times as much as the power provided by BMW’s original Brake Energy Regeneration.

Generator delivering electrical braking force.

In the generator mode, the two electric motors recapture much of the energy that must be dissipated to slow the vehicle. The stopping force generated in this way is up to 0.3 G, significantly reducing the demands 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 by a control unit into brake power generated by regeneration and conventional hydraulic braking. 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 X6 ActiveHybrid employs an electrical vacuum pump. A mechanical failsafe function guarantees full operation of the brake system in the event of a failure or a fault in the electrical system. In this 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 maximize the use of brake force available through the regeneration process. Via the xDrive powertrain, the hybrid system in the BMW X6 ActiveHybrid is able to transmit regenerative brake forces to all four wheels. 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 Dynamic Stability Control, affecting brakes and engine management to keep the vehicle safely on course. This ensures safe braking under all conditions, regardless of whether the stopping power needed is generated electrically or hydraulically.

All driving stability systems are tailored to the dynamic character of the BMW X6 ActiveHybrid. Dynamic Traction Control, 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 driving all the way to a controlled slip in corners.

BMW xDrive: intelligent all-wheel drive for extra performance, optimum driving stability and traction.

The sporty driving behavior of the BMW X6 ActiveHybrid is due largely to BMW’s xDrive all-wheel-drive system. Electronically controlled, variable distribution of drive power front-to-rear gives the BMW X6 ActiveHybrid superior traction and enhanced driving dynamics.

xDrive features smooth division of drive power through a transfer case with an electronically controlled multiple-plate clutch that feeds power to the axle with optimum wheel contact and grip on the road. Under normal conditions BMW xDrive distributes drive power to the front and rear axle in a 40:60 split. Sensors constantly measure wheel slip at both the front and rear, and varies the balance of drive power within a fraction of a second. Unlike conventional all-wheel-drive systems, xDrive “looks ahead” and does not only respond when a wheel has already begun to spin.

Electronic Power Steering for even greater efficiency.

The BMW X6 ActiveHybrid is the first Sports Activity Vehicle to feature Electronic Power Steering. This allows variable steering assistance both when driving with the combustion engine and in the all-electric mode.

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

Liquid cooling for even greater performance on the high-performance battery pack.

The high-voltage, nickel-metal hydrid technology (NiMH) battery pack featured in the BMW X6 ActiveHybrid has a total capacity of 2.4 kWh, with 1.4 kWh available nominally. Maximum output is 57 kW, with the battery’s control unit constantly determining the output level currently available as well as the charge status of the battery.

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

Cooling by the air conditioning system is activated by an appropriate switch valve, with the electrical climate compressor being switched on automatically whenever required. The battery cooling function is separate from the vehicle interior cooling function. Using the air conditioning system for battery pack cooling is far more efficient and effective than using air cooling alone to maintain the battery pack at the optimum operating temperature thereby preserving the hybrid functions longer in extreme weather and sport driving conditions. As befits The Ultimate Driving Machine, the BMW X6 ActiveHybrid provides a driving experience like no other hybrid in the marketplace.

Intelligent energy management and integral safety concept.

The electronics for BMW ActiveHybrid have been developed especially for energy efficiency and driving flexibility. The control system constantly controls the distribution of energy as a function of ambient conditions, the status of the vehicle, and the demands made by the driver. The two overriding control factors are the charge status of the battery pack and the capture of energy generated through regeneration.

The BMW X6 ActiveHybrid fulfills BMW’s integral safety concepts that have been updated for hybrid vehicles. Examples of the features of this safety concept are the different colors of cables to avoid confusion, the presentation of clear safety warnings, and protection of the entire electrical system via extra-large insulation panels and newly developed connectors.

The high-voltage battery pack is housed in a reinforced steel casing and is located just above the rear axle at an extremely safe location in the event of a collision. The status of the battery pack is constantly supervised by integrated safety electronics, and the driver will be informed immediately of any malfunction and, if necessary, the entire system can be automatically discharged and deactivated. In the event of a crash, the system is switched off automatically within a fraction of a second. The central safety electronics then assess the severity of the accident and ensure a safe operating mode if possible.

Hybrid-specific Auto Start Stop function.

The BMW X6 ActiveHybrid is equipped with a new generation of Auto Start Stop technology, specifically tailored to the requirements of a hybrid vehicle. Auto Start Stop functions at all ambient temperatures. While the engine is switched off, the electric air-conditioning compressor automatically maintains the climate and temperature desired within the passenger compartment. All other electrically operated functions continue uninterrupted, with the on-board network supplied with power from the battery pack. The hybrid Auto Start Stop can be deactivated by choosing the Manual gearshift mode on the automatic transmission.

Displays inform the driver of the operating status and efficiency of the hybrid system.

Status of the hybrid system and current operating conditions are presented in two locations. The most important information is shown in the instrument cluster, separated according to operating mode. Further information and technical explanations are shown in the Central Display.

The drive displays are split into a conventional tachometer for the combustion engine and electric drive display in the lower part of the instrument cluster. The electric drive display shows the charge status of the battery pack, the regeneration status, and the electric motor operating status. In the Central 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 suspension is a double A-arm configuration ensuring excellent driving dynamics, comfort, and directional stability. Self-leveling with air suspension provides a constant ride height, even when carrying a heavy load.

Lightweight brakes decelerate the BMW X6 ActiveHybrid by means of aluminum floating calipers and brake rotors incorporating aluminum hubs (or hats). Lightweight materials engineering reduces unsprung mass and improves the vehicle’s driving comfort and agility. Brake disc diameter is 15.2 inches up front and 13.6 inches at the rear.

20-inch light-alloy Aero wheels featuring an aerodynamically optimized design have been developed exclusively for the BMW X6 ActiveHybrid. 19-inch light-alloy wheels with all-season tires are available as an option. In each case the tires feature runflat technology which enables the driver to continue driving after a complete loss of pressure.

Bodyshell and safety: intelligent lightweight construction, optimized occupant safety.

Intelligent lightweight construction and a special body structure for maximum rigidity also characterize the unibody of the BMW X6 ActiveHybrid.

The BMW X6 ActiveHybrid comes with three-point inertia-reel seat belts for all seats featuring belt force limiters and belt pretensioners 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. The vehicle is equipped with frontal and hip thorax airbags, and side-curtain head airbags.

All restraint systems are controlled by central safety electronics including rollover sensors. The system can activate the side-curtain airbags and belt pretensioners in the event of an impending rollover.

Standard adaptive bi-xenon headlights ensure optimum illumination of the road ahead by steering with the vehicle. A daytime running light function operates through the corona rings. The BMW X6 ActiveHybrid also features a windshield-mounted sensor that automatically controls the lights and windshield wipers on demand. Additional comfort at night is provided by available Automatic High Beams which will automatically dim the high beam headlights when an oncoming vehicle is detected. The standard Head-Up Display projects information relevant to the driver onto the windscreen.

The BMW X6 ActiveHybrid: Sports Activity Coupe of the highest standard, BMW ActiveHybrid with maximum efficiency.

The BMW X6 ActiveHybrid combines an innovative vehicle concept with cutting-edge drivetrain technology to provide a truly unique driving experience. The enhancement of both dynamic performance and efficiency gives BMW’s Sports Activity Coupe additional appeal. BMW ActiveHybrid technology helps to achieve a high level of efficiency in this versatile model.

From outside the BMW X6 ActiveHybrid differs from the conventional-drivetrain models in only a few details. With its elegant and dynamically flowing roofline and features typical of a BMW, the Sports Activity Coupe offers a uniquely sporting rendition of this very special vehicle with its unprecedented character, now as a full hybrid variant.

The “powerdome” hood distinguishes the vehicle from outside, “ActiveHybrid” model designations on the tailgate trim bar and the front doors as well as Bluewater Metallic paint offered for the first time on a BMW X6. Apart from the specific hybrid displays in the instrument cluster, door entry trim covers bearing the designation “BMW ActiveHybrid” on the driver’s and front passenger’s doors add a particular highlight and sign of distinction.

Bmw7

With the launch of a new generation of BMW 7-Series High Security sedans based on the BMW 7-Series, the leading supplier of premium vehicles meets the most stringent safety requirements for persons at risk while travelling in their vehicles. Both, the BMW 760Li High Security and the BMW 750Li High Security are the first models in the world to be certified to BRV 2009 and both vehicles meet the requirements of the new ballistic protection level VR7. Due to their highly effective protective armour, the non-transparent body areas of the BMW 7-Series High Security meet the requirements of the ballistic protection level VR9. Hence, both the BMW 760Li High Security and the BMW 750Li High Security provide optimum safety in the individual mobility segment in combination with unparalleled comfort of travel, superior drive technology and an abundance of innovative equipment features to guarantee confident motoring at all times.

The two BMW 7-Series High Security sedans set new standards in the protection of persons at risk while travelling in their vehicle. The unique security concept is based on findings which BMW gained as a result of its determined development work and on more than thirty years of experience in security vehicle engineering. The security concept was developed parallel to the production model and the integration of safety components is an integral part of the vehicle production process at BMW’s Dingolfing plant. Specific chassis components are perfectly adapted to the increase in weight due to the sedans’ armour plating. Hence, reinforced suspension, dampers and suspension strut top mountings are part of the model-specific component range. This approach ensures finely-tuned vehicle performance characteristics that cannot be achieved by retrofitted armour plating.

// // Reinforced vehicle-specific armour plating made from special steel as well as newly developed safety glazing protect the passenger compartment in particular from attacks of all kinds. The passenger compartment is protected by armour plating of the doors, the roof, the pillars, the front footwell and the separation wall between passenger and luggage compartments. The steel panels, which were manufactured by means of a special technique, fit the body contours perfectly. The model-specific gap sealing ensures that critical areas such as door cut and body joint lines are safely sealed.

The sedans’ undercarriage is armoured by special plating which was developed with a particular focus on maximum explosion protection. Another new development is the sedans’ 2.4″ (6 cm) safety glazing. Due to its innovative structure, the multi-layer laminated glass cover provides a unique level of resistance. The window panes are covered with a polycarbonate layer on the inside in order to prevent shattered glass particles from penetrating the interior.

Driving dynamics and comfort on a par with production models.

Even with the highly effective security equipment, both the exclusive character of the interior as well as the driving dynamics that are typical of BMW 7-Series luxury sedans has been virtually retained. Despite their extensive safety equipment, BMW 7-Series High Security can hardly be distinguished from the corresponding production models.

The sedans’ high protection level, which is second to none, is combined with a prestigious appearance, outstanding comfort of travel and an impressively powerful drive system. Both the BMW 760Li High Security’s twelve-cylinder engine and the BMW 750Li High Security’s V8 engine offer a combination of all-aluminium design, BMW TwinPower Turbo Technology and High Precision Injection with direct fuel injection. Both power units are distinguished by their energetic power delivery from a low number of revolutions, the running smoothness that is typical of BMW luxury sedans and their state-of-the art efficiency. Despite the increased weight of the vehicle, the engine performance characteristics of both models ensure that the new high-security sedans can achieve a dynamic acceleration from standing and a confident engine torque at all speeds. Both models have an electronically limited top speed of 210 km/h.

The newly developed V12 unit of the BMW 760Li High Security unleashes its superior power of 400 kW/544 hp at an engine speed of 5,250 rpm. Peak torque of 750 Nm comes at 1,500 rpm. In combination with the newly developed eight-speed automatic transmission, the 6.0-litre twelve-cylinder engine impresses drivers not only with its outstanding running smoothness, but also with its ability to spontaneously translate its seemingly infinite power reserve into precisely adjustable driving dynamics anytime. The BMW 760Li High Security accelerates from zero to 100 km/h in as little as 6.2 seconds.

The 4.4-litre eight-cylinder engine of the High Security is the first petrol engine of its kind with turbochargers that are located in the “V”BMW 750Li space between the cylinder banks. The V8 engine achieves 300 kW/407 hp at engine speeds of between 5,500 and 6,400 rpm. It mobilizes a maximum torque of 600 Nm that is maintained between 1,750 and 4,500 rpm. The spontaneously delivered engine thrust is applied to the rear wheels via a six-speed automatic transmission. The BMW 750Li High Security accelerates from 0 to 100 km/h in 7.9 seconds.

The BMW 7-Series High Security are distinguished by particularly harmonious driving characteristics. Both the comfort and the active security features of both models correspond to the premium quality standards that are typical of the BMW 7-Series. The innovative and in part exclusive BMW driver assistance systems ensure that potentially dangerous traffic situations can be foreseen and avoided, thus allowing for confident motoring.

The combination of a double wishbone front axle with an integral V rear axle provides numerous benefits in terms of comfort and dynamics, but above all, it results in an outstandingly harmonious handling of curves, virtually eliminating rolling, swaying or tilting behaviour. Moreover, the BMW 760Li High Security and the BMW 750Li High Security are equipped with an electronically controlled Dynamic Damping Control. The dampers adapt to the road surface as well as to the style of motoring.

The high-performance braking system ensures excellent deceleration values in all situations. Inner-vented discs and sliding calliper design for optimum efficiency on all four wheels provide extreme stability and maximum braking comfort. Run-flat tyres are equipped with temperature sensors and a separate tyre pressure monitoring system for each wheel.

Special options for individual security requirements.

Just like the range of comfort options, the security package for the BMW 7-Series High Security can be adapted to suit individual requirements. An intercom system with concealed microphones and speakers allows safe communication with people outside of the vehicle without the need to open doors or windows. Additional safety options include an assault alarm, fire extinguishing system with temperature sensor for extinguishing fires in the engine compartment and below the vehicle as well as irritant gas sensors for protecting passengers from gas attacks. If the interior protection system is triggered by excess gas levels, all windows are closed automatically, the central locking system is activated, the fresh air valves are closed and the ventilation system is shut off. An additional internal fresh-air supply system ensures that passengers are provided with breathable air.

BMW also offers special options for authorities, governments and embassies. The package provides a range of special features such as flag holders, arrangements for radio installations right through to a gun case with compartments for two machine guns in the center console. Also included is an external beacon with a roof installation system and integrated LED flashing lights for the front grille. Upon request, the vehicle may be fitted with an acoustic signalling system that can be controlled via the iDrive operating system.

In order to accommodate this exclusive circle of customers, BMW provides discreet consultancy and personalized sales and service support all over the world. BMW high-security sedans are serviced by certified special garages only. Access to the vehicles is restricted to very few selected and specially trained personnel. As part of the special customer service, BMW offers special driver training programs for security vehicles.
