With Cameron Diaz now officially set to ride in the BMW Hydrogen 7 to the 2008 Oscar Awards, more unofficial details are coming out that BMW is planning to launch a Hybrid 7 Series in the next 2-3 years. We have blogged about hybrid BMW models before. In fact, just last April, we spoke about a Hybrid 5 Series model possibly in the works. Now, rumor has it that the flagship 7 Series will get the eco-friendly powerplant first.
Likely a joint venture between BMW, General Motors, and Mercedes-Benz, the new powerplant will be a "mild" hybrid system. This type of hybrid recovers energy from braking (aka "regenerative braking") to be stored and used to supplement the internal combustion engine. The Hybrid 7 Series will have to ultimately rely on gasoline for propulsion, as this type of hybrid is not able to run in pure electric mode like the Porsche Cayenne Hybrid.
With the news of BMW's twin-turbo diesel hybrid X5 fresh on our minds, it seems 2008 is turning out to be a green year for the German automaker.
