Detroit Diesel Corporation is an affiliate of Daimler Trucks North
America LLC, and is a leading manufacturer of on-highway, heavy-duty, diesel engines for the commercial truck market.
The company offers a complete line of engines for the on-highway and vocational markets.
Through its corporate headquarters in Detroit, Michigan, Detroit Diesel is engaged in the design, manufacture, sale and service of these products, in addition to supporting alternative and hybrid engine strategies for the commercial truck marketplace.
Detroit Diesel was founded in 1938 and has built more than 5 million engines to date. Currently the company has more than
1 million engines in operation worldwide. The Series 60 has been the top selling heavy-duty diesel engine since 1992, and in 2008, the company built its one millionth Series 60 engine.
The revolutionary DD15, launched in 2007, opened a new era in heavy-duty engines -- offering pulling power, affordable fuel economy, bullet-proof reliability and easy maintenance on a single engine platform. In September of 2008, DD15 engine orders surpassed Series 60 orders.
The Detroit Diesel DD13, launched in 2008, is designed specifically for less-than-truckload, regional distribution and vocational applications. It offers the same serviceability and performance -- and up to 5% better fuel economy -- than the DD15. In the medium duty range, Detroit Diesel has shipped more than
115,000 MBE 900 engines in North America since 2002.
