BMW 7 Active Hybrid concept
Toronto, Ontario – BMW premiered its Concept 7 Series ActiveHybrid sedan at the Canadian International Auto Show on Wednesday. The company says the hybrid luxury car reduces fuel consumption and emissions by 15 per cent (EU test cycle) versus a similar car running on a combustion engine only.
The BMW Concept 7 Series ActiveHybrid is powered by a V8 gasoline engine with Twin Turbo and High Precision Injection based on the power unit of the BMW 750i. Maximum output of the conventional engine in the regular production model is 400 horsepower, with peak torque of 450 lb-ft. This engine is combined with an electric motor fully integrated in the transmission housing, developing maximum output of 20 hp and peak torque of 155 lb-ft (European specifications). Using the mild hybrid concept, the electric motor boosts the dynamic driving potential of the eight-cylinder gasoline, giving the car even more dynamic acceleration.
Using Brake Energy Regeneration, the electric motor supplies power to a high-performance lithium-ion battery integrated in the trunk. The electric energy generated is supplied to the power-consuming items on board the car, minimising the direct conversion of fuel into electric energy and maximising the power available for driving dynamics.
The BMW Concept 7 Series ActiveHybrid is based on the BMW 7 Series luxury sedan. BMW will introduce the 5th generation of its flagship sedan in spring 2009. The sleek and sophisticated new exterior profile of the new 7 Series was designed by Canadian designer Karim Habib.
