Detroit announced a milestone in its heavy-duty engine production (HDEP) with its one-millionth engine produced at the manufacturing facility located in Redford, Michigan.

The HDEP product family at Detroit includes DD13, DD15, and DD16 engines, all produced in-house, according to Detroit's news release. The company held an all-campus celebration on Dec. 7 at the Redford campus to commemorate this event and recognize all employees and workforce who have helped achieve this milestone.

“Detroit has been building world-class, state-of-the-art engines with industry-leading technology for over 84 years,” said Matt Pfaffenbach, head of operations at Detroit. “The campus is home to 2,900 employees. Our work is built on a foundation of pride, hard work, and innovation. We are extremely proud of this achievement and the advancements we bring to the industry. Our Detroit heavy-duty engines provide customers with the best fuel efficiency and economy with millions of miles of reliability and durability. Producing one million heavy-duty engines in the Detroit plant is a huge achievement and we are excited to keep that momentum going.” 

Detroit added that it provides engines for both the on-highway and vocational commercial customers. Through these advancements, Detroit aims to improve engine fuel economy by 5% every two to three years.
