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
McKeen Motor Car Company first run was on May 9, 2010, the car's hundredth anniversary of construction. The original powerplant did not survive, and no other McKeen engines could be located. Consequently, a modern diesel engine was fitted to allow the car to operate up to the original maximum speed. The fully restored McKeen motorcar was put back into operation on May 9, 2010, right on schedule for its 100th anniversary of its construction. The motorcar is now being used at the Nevada State Railroad Museum In Carson City Nevada for special occasions such as Independence Day and Nevada Day The NSRM also owns
