The Mercedes-Benz 300GD (later the G300 D), was a diesel powered variant of the W463 G-Class that was introduced for 1990. Available in both short and long wheelbase versions, as well as convertible or wagon body styles, the 300GD was powered by Mercedes' OM603 D30 engine. This 3.0L inline six diesel engine generated 113hp and 141 lb ft of torque. Drive was sent from the engine to all four wheels via a 5 speed manual or 4 speed automatic transmission. In late 1993, Mercedes changed their naming system, moving the letter designation to the front of the displacement designation, thus changing the name of the 300GD to the G300 D. A total of 4,163 examples of the Mercedes-Benz 300GD/G300 D were built before the end of production in 1994.
