The Mercedes-Benz 300CD Turbodiesel was a diesel-powered variant of the C123 Coupe that was exlusive to the North American market. The 300 TD Turbodiesel was powered by Mercedes' OM617.952 engine, which was 3.0L turbocharged inline five. This powerplant initially generated 121hp and 170 lb ft of torque, but a technical update for the 1983 model year saw output increase to 125hp and 184 lb ft of torque. This power was sent to the rear wheels through a 4 speed automatic transmission. Production of the Mercedes-Benz 300D Turbodiesel ended in 1985, with a total of 8,007 examples built.
