The Mercedes-Benz S600 was a variant of the W221 S-Class that was introduced for the 2007 model year in North America (2006 in Europe). The S 600 was the top non-AMG offering for the W221, and was powered by Mercedes' mighty M275 engine. The M275 was a 5.5L V12 powerplant that generated 510hp and 612 lb ft of torque. Power was sent from the engine to the rear wheels via a 5 speed automatic transmission. Production of the W221 S600 ended in 2013, although the model series continued life in the next generation W222 Mercedes-Benz S-Class as the W222 S600.
