Almost $1 billion will be invested by General Motors into its DMAX engine operation in Ohio that’s set to continue building internal combustion engines for heavy-duty trucks.

As it stands, the site in Brookville encompasses some 250,000 square feet but will be expanded by an additional 1.1 million square feet. This site currently builds engine components for the DMAX site in Moraine, Ohio that was originally formed through a joint venture between GM and Isuzu Diesel Services of America back in 1999.

“This investment furthers our commitment to HD truck market dominance with the Duramax power under the hood that customers love so much,” GM’s North America manufacturing vice president Mike Trevorrow said. “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.”

While GM is failing to provide any details about future engines that will be built at the factory, Auto News understands that current employees from the Moraine facility will be moved to the Brookville site as production ramps up.

“We have no announcements to make at this time beyond the current product for the Moraine plant, but after this engine program builds out the plant may be considered as we evaluate future program allocation,” a GM spokesperson added.

The huge investment has been well received by Carl Kennebrew, the international president of the International Union of Electrical Workers-Communications Workers of America union that represents hourly employees at DMAX.

“This historic investment and expansion announcement is a testament to the work ethic of the IUE-CWA members at this company and I could not be prouder,” he said.

News of GM’s significant investment into heavy-duty truck engine production comes less than two weeks after the carmaker said it will invest some $632 million into its Fort Wayne Assembly site for the production of next-generation full-size light-duty pickup trucks with combustion engines.
