The new BMW 7 Series Hybrid has been spotted again somewhere in Munich. The 7er Hybrid which was unveiled at the L.A Auto Show in November uses a twin-turbo 4.4-litre V8 petrol engine that delivers 407 horsepower and 442lb ft, working in combination with an AC electric motor that can add another 20 horserpower and 155lb ft of torque.
In mild hybrid form, the result is 15 percent less fuel consumption and emissions (in the EU test cycle) versus a combustion engine only equivalent.
The 7 Series Hybrid comes as a response to the Lexus LS 600hL and Mercedes-Benz’s S400 Bluetec Hybrid which was unveiled in 2007 at the L.A Show.
To improve even more the fuel efficiency, the start/stop technology and the part-time alternator have been implemented in the Hybrid version as well. Other standard hybrid features, such as regenerative braking and optimized aerodynamics.
The system uses a modular hybrid system which can be adapted to many different engine/vehicle combination, as opposed to a design-specific petrol engine/hybrid combination, which sees wider use in the automotive industry and it was jointly developed with Daimler, Chrysler and General Motors.
The 2010 BMW 7 Series Hybrid will go on sale late this year.MotorAuthority ]
