History of the diesel car and considerably lighter than the in-line six-cylinder it also replaced, this 3.0L V-6 produces 165 kW (224 hp) at 3,800 rpm and max torque of 510 Nm (376 ft·lbf) at 1,600-2,800 rpm and makes use of a four-valve head. Additionally, fitment of Mercedes-Benz BlueTec system, a concert of emissions control strategies, renders this new diesel 50-state legal in the U.S. beginning in 2008 (stringent NOx limits have made U.S. passenger-car diesels unpopular or impossible in parts of the U.S. in recent years). In 2006, the new Audi R10 TDI LMP1 entered by Joest Racing became the first diesel-engined car to
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.
