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
Budd Rail Diesel Car steel, including the technique of shot welding to join pieces of stainless steel. This permitted the construction of cars which were both light and strong. Budd partnered with Michelin to construct several rubber-tyred stainless steel rail cars powered by gasoline and Diesel engines. These saw service with the Reading Company, Pennsylvania Railroad, and Texas and Pacific Railway. The cars were underpowered, the tires proved prone to blowouts and derailments, and the cars were unsuccessful. Budd revived its railcar concept after diesel engines with a suitable combination of power and weight became available in 1938, although with more conventional steel wheels.
