2009 BMW Efficient Dynamics Concept

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.

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.

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.

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.

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.

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.

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.

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.

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.

2010 BMW 7 Series high security

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.
