Detroit is a commercial vehicle powertrain and technology brand within Daimler Truck North America. Known historically as Detroit Diesel, the company supplies diesel engines, automated manual transmissions, axles, and connected vehicle technologies used in commercial trucking.

Detroit equipment is closely associated with Freightliner and Western Star trucks. Truck Equipment Atlas brings together Detroit product profiles so drivers, owner-operators, fleet managers, technicians, and equipment buyers can explore the components that power and support these vehicles.

History and Background

Detroit’s history began in 1938 with the General Motors Diesel Division. Its early diesel engines established a foundation for a business that would become widely recognized in commercial transportation and other demanding applications.

The Series 60 engine, introduced in 1987, became an important part of Detroit’s trucking history. It helped establish the company’s reputation for electronically controlled heavy-duty diesel engines and remains relevant to owners and technicians working with older trucks.

DaimlerChrysler acquired Detroit Diesel in 2000. Today, Detroit operates within Daimler Truck North America, with a product portfolio extending beyond engines to integrated powertrain components, driver-assistance systems, connected vehicle services, and electric propulsion technology.
