2010 BMW 7-Series ActiveHybrid debuts
BMW has debuted the production hybrid version of the BMW 7-Series. To be shown at the 2009 Frankfurt Auto Show in September, the 2010 BMW ActiveHybrid 7, as well as the 2010 BMW ActiveHybrid X6, will go on sale in early 2010.
This symbiosis of an upgraded twin-turbo, High Precision Direct Injection, V8 engine with a 3-phase synchronous electric motor gives the BMW ActiveHybrid 7 a combined output of 455 hp and maximum torque of 516 lb-ft. 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 ActiveHybrid 7. The result is a unique driving experience that demonstrates the performance capabilities of modern hybrid technology. The BMW ActiveHybrid 7 accelerates to 60 mph in 4.8 seconds, while delivering fuel economy approximately 15% better than the 750i.
BMW ActiveHybrid technology also provides new features that promote efficiency while preserving comfort. As an example, the BMW ActiveHybrid 7 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.
The BMW ActiveHybrid 7 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.
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 ActiveHybrid 7 has a wheelbase increased by 5.5 inches, 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.
While the ActiveHybrid 7 is a mild hybrid, the BMW ActiveHybrid X6 crossover SUV offers more electric power and performance.
