Detroit Diesel

in Diesel
Detroit Diesel Corporation (DDC) is a diesel engine producer headquartered in Detroit, Michigan, USA. There are today two divisions that share this name:

The off-highway division which is owned by Tognum, which EQT IV formed along with MTU Friedrichshafen.

The on-highway division which is owned by Daimler AG.

Detroit Diesel was part of the Freightliner - Trucks NAFTA Business Unit of DaimlerChrysler (now Daimler AG and Chrysler LLC respectively) until it was split into two. The on-highway part of Detroit Diesel remains a part of this division, with the sale of the off-highway division to EQT IV.

The company produces on-highway medium and heavy-duty Diesel engines for the commercial truck market, and for other commercial and automobile use. Engines range from 170 to 560 hp (127 to 418 kW), soon to be expanded to 600 hp (448 kW) with the introduction of the DD16 engine in 2010, for the on-highway market. The Series 60 has been the market share leader since 1992, and combined with the MBE 4000 has 27% of the Class 8 market. Worldwide there are over 1,000,000 Series 60's, and over 350,000 MBE 900's, in operation.
