The Mercedes-Benz 300D was a diesel powered variant of the W123 Sedan. Introduced for the 1977 model year, the 300 D was powered by Mercedes' OM617.912 inline five engine. This 3.0L diesel powerplant was originally rated at 80hp, but an update for the 1980 model year increased output to 88hp. Power was sent from the engine to the rear wheels via manual or automatic transmission options. Mercedes also offered a long wheelbase (LWB) version of the 300D, known as the V123 Mercedes-Benz 300D. Although production of the 300D lasted until 1985, in North America, the 300D was replaced by the Mercedes-Benz 300D Turbodiesel for the 1982 model year. By the end of production, a total of 324,718 examples of the 300D had been built.
