Detroit, a provider of North American engine technology for commercial vehicles, and a part of Daimler Truck North America (DTNA), marked its 85th anniversary. From beginnings at its flagship facility in Redford, Michigan, the company has thrived.
Founded in 1938 as part of General Motors, GM Diesel Division, Detroit set out with one focus: crafting top-tier engines for heavy- and medium-duty trucks. Over the decades, it expanded its product line to encompass more than state-of-the-art engines, including automated manual transmission, axles, battery-electric components for zero-emission vehicles, and cutting-edge technologies for enhanced connectivity and safety.
Looking Back at Detroit History
To date, Detroit has produced 1.1 million heavy-duty engines (DD13, DD15, and DD16) and employs nearly 3,000 Daimler Truck employees. Detroit continues to achieve milestones in manufacturing with the goal of ensuring all products and services provide a comprehensive solution to meet the ever-evolving needs of customers.
Detroit’s commitment to environmental sustainability is evident through its partnership with the U.S. Department of Energy’s Superior Energy Performance (SEP) program, with the Redford campus achieving the prestigious SEP 50001+ platinum level status. Daimler Truck North America, DTE Energy and the state of Michigan also recently announced partnering to build a federally funded charging hub located next to the Redford campus to provide a more accessible charging infrastructure to those within the industry.
“Detroit is extremely proud of our rich 85-year history in the transportation industry,” said Matt Pfaffenbach, Detroit Plant Manager. “Our remarkable milestones and success are attributed to loyal customers who drive our Detroit products on the road each and every day. This level of success only becomes possible with dedicated employees who design, build and deliver our industry-leading products. They have shaped our past and will play a key role in forging our future path.”
