DaimlerChrysler will begin sale a hybrid version of S-Class luxury sedan in 2008. Whereas the LS600h L is a full hybrid pairing a 4.3L V8 with a pair of electric motors, the Mercedes-Benz S-Class hybrid will likely be a mild hybrid. Both the Direct Hybrid and Bluetec Hybrid concepts shown at the 2005 Frankfurt motor were mild hybrids, meaning the electric motors only assist the engine, though the former paired its electric motor with a 3.5-liter gasoline engine and the latter used the 3.0-liter Bluetec diesel.
