As an integral part of the BMW EfficientDynamics strategy, the BMW Concept 7 Series ActiveHybrid previews the potential of BMW ActiveHybrid technology in a luxury sedan. In typical BMW fashion, this new concept car combines a significant reduction of fuel consumption and emissions with a level of driving dynamics never seen before even in this class of hybrid cars.

The BMW Concept 7 Series ActiveHybrid is an intelligent symbiosis of BMW's new twin-turbo V8 engine and electric drive as a mild hybrid concept. A compact electric motor, integrated into the transmission housing, replaces the conventional alternator as well as the starter. Power to run all electrics on-board the car is generated by means of Brake Energy Regeneration. The combination of internal combustion engine and electric motor take the twin-turbo 4.4-liter V8's already potent 400 horsepower and 450 lb-ft of torque and supplies an additional 20 horsepower and up to 155 lb-ft of torque as needed. The drivetrain technology featured in the concept car allows enhanced driving dynamics together with a reduction of fuel consumption and emissions by 15 percent in the EU test cycle compared to the same car running on a combustion engine alone. At the same time the use of BMW ActiveHybrid technology does not require any compromises in driving qualities and features of the BMW 7 Series.

Energy is stored in a compact lithium-ion battery housed in the luggage compartment. An Auto Start Stop function helps to ensure optimum efficiency in all driving situations.

The hybrid technology showcased in the BMW Concept 7 Series ActiveHybrid is perfectly suited to the new benchmark in the full-sized performance luxury sedan segment just as the two-mode hybrid technology used in the BMW Concept X6 ActiveHybrid, also on display in Los Angeles, is well matched to the world's first Sports Activity Coupe.
