As Detroit observes its 80th anniversary this year, parent company Daimler Trucks North America LLC (DTNA) is marking another important achievement – the production of its 1 millionth heavy-duty engine platform (HDEP) engine. The 1 millionth HDEP engine is a shared milestone between Detroit’s Redford, Mich.-based manufacturing facility and Daimler AG’s Mercedes-Benz plant in Mannheim, Germany.

Introduced in 2007, HDEP was jointly developed in Germany, Japan and the United States. HDEP engines have 90% shared parts worldwide, which has resulted in significant cost savings and uptime efficiencies.

The first HDEP engine launched in North America was the Detroit DD15 engine, which today leads the industry with more than 60% market penetration and best-in-class fuel efficiency. The Detroit DD13 and Detroit DD16 engines were later introduced to meet the needs of additional heavy-duty applications. 

Detroit offers a complete line of heavy-duty diesel engines, transmission, axles, safety systems and connected vehicles services. Most recently, Detroit began production of the Detroit DD8 engine, complementing the mid-range Detroit DD5 engine.

The state of Michigan recognized the company’s contribution to the industry and the community by declaring June 14 as Detroit Diesel Corporation Day, and the company will continue to celebrate its anniversary with a series of events throughout the remainder of the year.
