GM is set to invest almost $1 billion into the DMAX plant in Brookville. The investment will support production of internal combustion engines set for use in the automaker’s heavy-duty truck line, including a considerable expansion to the facility’s footprint. Construction is set to begin immediately.
According to a recent report from WDTN, GM announced the new investment at the DMAX plant in Brookville on Friday. The $920 investment will quadruple the existing facility footprint, adding 1.1 million square feet of space. Site development was recently approved by officials, as GM Authority covered previously. GM purchased 53 acres of land near the existing DMX Brookville plant late in 2021. The parcel was left largely untouched in the years since.
Per previous GM Authority coverage, some are worried that the expansion to the DMAX Brookville plant will move jobs away from the GM DMAX Moraine plant in order to support the newly expanded Brookville facility. DMAX serves as a joint venture between GM and Isuzu, with GM holding a majority stake. The joint venture is responsible for producing diesel engines found throughout GM’s lineup.
The $920 million slated for the DMAX plant in Brookville is only the latest investment news to come from GM as of late with regard to its heavy-duty truck line and internal-combustion engines. The General also recently announced a massive $1 billion investment for its Flint Assembly and Flint Metal Center manufacturing sites in Michigan to support full-size pickup production and next-generation ICE-based heavy-duty trucks, with $788 million for the GM Flint Assembly plant for a body shop expansion, general assembly conveyor expansion, new tooling, and equipment, as well as a further $233 million for the Flint Metal Center for new stamping dies, press refurbishments, and new equipment.
GM has also announced a $632 million investment for its Fort Wayne Assembly plant in Indiana to support next-gen ICE-based light-duty truck production, $209 million for the GM Oshawa plant in Canada to support ICE-based HD truck production, and $500 million for the GM Arlington plant in Texas to support next-gen full-size SUV production.
