The Mercedes-Benz 240D was a diesel-powered variant of the W115 that was introduced for the 1974 model year. The 240D was offered in a four door sedan body style, but was available on the standard or long wheelbase. In addition to the factory built sedans, various coachbuilders offered station wagons built using the 240D. These cars were powered by Mercedes' OM616,916 engine, which was a 2.4L diesel inline four that produced 64hp and 101 lb ft of torque. This power drove the rear wheels via a 4 speed manual or 4 speed automatic transmission. The W115 Mercedes-Benz 240D was in production until 1976 and saw a total of 126,148 examples built. The 240D model series would continue life as the next generation W123 Mercedes-Benz 240D.
