A proud tradition of building engines with strength, quality and dependability began for Detroit in 1938, when it was known as the General Motors (GM) Diesel Division. The heavy-duty, on-highway Series 71 engine was used extensively in military and road-building and was followed by the Series 53 model, another powerhouse with wide-ranging applications.

In 1965, GM Diesel became the Detroit Engine Division, partnering with the transmission and gas-turbine business of the Allison Division, forming Detroit Diesel Allison. Sales tripled. By the 1980s, Detroit Diesel had split from the Allison Division, when the Series 60 was developed to meet the demand for a cleaner, more fuel-efficient heavy-duty engine. The Series 60 quickly became the most popular heavy-duty engine in the North American class-8 segment.

 

 

A late-1980s joint venture between Penske Corporation and GM created Detroit Diesel Corporation. In 2000, Daimler-Chrysler acquired the business, making Detroit Diesel a subsidiary of Daimler Truck North America. In 2011, Detroit Diesel expanded its design and manufacturing scope beyond engines, simplifying its name to Detroit. Beginning in 2021, Detroit entered the zero emissions market with a line of battery electric products. Today, Detroit products and services are supported by a parts and distribution network of over 700 locations in North America.
