The Mercedes-Benz S430 4MATIC was a variant of the W220 S-Class that debuted in North America for the 2003 model year. The S 430 4MATIC was fitted with Mercedes' M113 E43 engine. This 4.3L V8 generated 275hp, which it sent to all four wheels via a 5-speed automatic transmission (The 5-speed automatic was upgraded to a 7-speed unit from the 2004 model year). Production of the W220 S430 4MATIC ended in late 2005, although the variant was sold in North America until 2006.
