Since 2000, Detroit Diesel Corporation has been a part of Daimler Trucks North America, joining Freightliner Trucks, Western Star Trucks, Thomas Built Buses and Freightliner Custom Chassis Corporation. In 2011, we branded our name from Detroit Diesel to Detroit, signaling the start of the company's expansion into new product categories, including transmissions, axles, connectivity, and safety solutions.
As a part of Daimler, Detroit has access to the global resources and expertise of the world’s foremost transportation company. It’s a relationship that benefits our customers every day.
