General Motors plans to expand production of future internal combustion engine heavy-duty truck powertrain products with a $920 million investment in its Duramax (DMAX) Brookville facility, near Dayton, Ohio.
The 1.1 million-square-foot expansion will more than quadruple the current size of the plant, which currently produces the Duramax 6.6L V-8 turbo-diesel available for the GMC Sierra and Chevrolet Silverado HD trucks. The investment will also add new technology and equipment.
The investment will bolster the company’s full-size truck businesses and provide jobs.
“This investment furthers our commitment to HD truck market dominance with the Duramax power under the hood that customers love so much,” said Mike Trevorrow, GM’s VP of North America Manufacturing. “Additionally, it is truly a testament to the hard work and dedication of our DMAX team members in the state of Ohio who build world-class powertrain products."
This announcement marks the third investment in Ohio manufacturing operations from GM in the last 10 months, including $55 million to support the production of V-8 engine block castings and future EV strategies in Defiance, Ohio.
Previously part of a joint venture, DMAX has been a wholly-owned subsidiary of GM since 2022.
In a news release announcing the investment, GM said the move bolsters its U.S. manufacturing operations, which include more than 50 assembly, stamping, propulsion, and component plants and parts distribution centers nationwide. It also noted this investment reinforces the OEM’s commitment to continue offering customers a “strong portfolio of ICE vehicles and propulsion systems for years to come.”
