History of the diesel car issue as a lot of diesel fuel contained water and also high levels of sulfur at the time. The engine was later revised into the DX block and most of the issues were fixed, a V6 version displacing 4.3 litres and a smaller 4.3 V8 were also offered around this time, mainly for the downsized front-wheel drive models of the mid-1980s and although they were much better in the reliability department, the damage had already been done and the North American diesel car market was severely crippled as a result, despite the best efforts by Mercedes-Benz, Audi, BMW, Peugeot, VW
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.
