History of the diesel car Production diesel car history started in 1933 with Citroën's Rosalie, which featured a diesel engine option (the 1,766 cc 11UD engine) in the Familiale (estate or station wagon) model. The Mercedes-Benz 260D and the Hanomag Rekord were introduced in 1936. Immediately after World War II, and throughout the 1950s and 1960s, diesel-powered cars began to gain limited popularity, particularly for commercial applications, such as ambulances, taxis, and station wagons used for delivery work. Most were conventional in design. Mercedes-Benz offered a continuous stream of diesel-powered taxis, beginning in 1949 with their 170D powered by the OM-636 engine. Later, in 1959
Edwards Rail Car Company of being up in the car body. Edwards output during the 1930s was mainly export cars including the "modern" streamlined Model-21 and the streamlined version of the Model-10, with their distinctive shovel-nose, first developed by Edwards in 1935. By the late 1930s sales of railcars in the United States was at an all-time low, and with the war in Europe, Edwards sold the plant and new owners re-tooled for defense production in 1940. In 1942 the Edwards Company lost its corporate identity and ceased to exist, rail motor cars and trailers were the only Edwards products manufactured under that name.
