Mercedes-Benz will be rolling out its new hybrid drivetrain in the form of the S400 BlueHYBRID during the third quarter of next year, but Mercedes’ newest green alternative won’t stay exclusive to its flagship model for long. Following the S400 BlueHYBRID’s introduction, Mercedes plans to launch hybrid versions of its C and E-Class cars.
Although technically a mild hybrid system, Mercedes views its new hybrid drivetrain as a way to meet upcoming CAFE regulations. Therefore the German automaker will be rolling out its new hybrid system in its C and E-Class cars in the coming years.

The E-Class will be the next model to receive the hybrid option, with the system expected to launch on the next-generation car in late 2009 or early 2010.

Following the E-Class hybrid, Mercedes will offer a mild hybrid version of its C-Class sedan. However, those wanting a little extra fuel economy in Mercedes’ entry-level sedan will have to wait slightly longer: The hybrid C-Class won’t be available until the next-generation car bows, likely sometime in 2011 or 2012.

No word on what gas engines Mercedes will pair with the new hybrid models, but it seems likely the E-Class hybrid will use the same 3.5L V6 used in the S400 BlueHYBRID. In S400-guise, the 3.5L pumps out 279 horsepower, with an electric motor contributing another 20 hp. Thanks to a lower curb weight, look for the E-Class hybrid to trump the S-Class hybrid in both acceleration and fuel economy.
