The Mercedes-Benz 240D 3.0, which was known as the 300D in North America, was a diesel-powered variant of the W115. Introduced for the 1975 model year, this family of cars was available from the factory in a four door sedan body style. As well as the factory sedan, a variety of coachbuilt station wagons were offered from a handful of coachbuilders. The 240D 3.0 / 300D was powered by Mercedes' OM617 engine, which was a 3.0L diesel inline five that generated 79hp and 127 lb ft of torque that was sent to the rear wheels via a 4 speed manual or 4 speed automatic transmission (Although only the automatic transmission was offered on North American cars). Production of the W115 Mercedes-Benz 240D 3.0 / 300D lasted until 1976, with a total of 53,690 examples built. The 300D model series would continue life in the next generation Mercedes-Benz E as the W123 Mercedes-Benz 300D.
