The Mercedes-Benz ML350 4MATIC was a variant of the W164 M-Class that was introduced for the 2006 model year. The ML 350 4MATIC was powered by Mercedes' M272.963 engine, which was a 3.5L V6 that generated 272hp and 258 lb ft of torque. Power from this engine was sent to all four wheels via a 7 speed automatic transmission. Mercedes-Benz also offered a ML 350 which sent power to the rear wheels. Production of the W164 Mercedes-Benz lasted until 2011, but the model series continued for the next generation M-Class as the W166 Mercedes-Benz ML350 BlueEFFICIENCY 4MATIC.
