Detroit Diesel Corporation (DDC), is headquartered in Detroit, Michigan, USA. The off-highway division is owned by Tognum, and the on-highway division is owned by Daimler AG. The company is perhaps best known for producing on-highway medium and heavy-duty diesel engines for the commercial use such as trucks and buses.
In 1938, General Motors formed their General Motors Diesel Division (GMDD) which produced two-cycle engines for use in tanks, landing craft, road building equipment, and as standby generators. In the 1950s, Detroit Diesel expanded into the on-highway truck market, and introduced the Series 53 and Series 71 engines in 1957.
GMDD became known as Detroit Diesel Engine Division in 1965, and five years later, General Motors later brought together their Detroit Diesel Engine with their Allison Division to form the Detroit Diesel Allison Division. In 1988 Detroit Diesel Corporation was formed from Detroit Diesel allison as a result of a Penske Corporation and General Motors joint venture.
In October 2000, DaimlerChrysler acquired Detroit Diesel, and brought together their engine and powertrain businesses into the Commercial Vehicle Division under DaimlerChrysler Powersystems. In 2008, it was announced that Detroit Diesel will not sell engines outside the Daimler family begining 2010. This would mean Setra would be the only bus manufacturer to use Detroit Diesel engines. Detroit Diesel later reversed their decision and announced in November 2009 their re-entry into the North American bus and coach market.
