Mercedes is currently testing the next generation S-Class->ke359 that will be unveiled at the end of the year. Codenamed the W222, the next S-Class will be inspired by the F700 Concept unveiled at the Detroit Auto Show.

What we know for sure is that the next S-Class will get blacked-out headlamps, a dummy front grille, and a new front bumper. Under the hood there will be a revised range of V6 and V8 engines. The base version will get a V6 engine with stop-start technology and revised direct injection that improves fuel economy. The top version will get a 4.6 liter V8 engine (down from the current 5.4 liter version) that delivers 429 HP and offers improved fuel economy. The diesel line-up will include a new base version called the S250 CDI and is powered by a 2.1 liter four-cylinder engine with 204 HP.

Also, the next S-class is believed to be the first model to use Mercedes’->ke187 radical Diesotto powerplant. The system was introduced in the F700 concept and it is in fact a four-cylinder with a displacement of only 1.8 liters, combining the strong points of the low-emission gasoline engine with the consumption benefits of the diesel drive.
