A new $175 million General Motors plant in Brookville, Ohio, will build components for the automaker’s highly popular Duramax diesel truck engines.

Located a few miles west of Dayton, this plant will be a part of GM and Isuzu’s joint DMAX venture. It will cover 251,000 square feet and employ more than 100 workers.

“Strong demand for GM’s all-new family of Chevrolet and GMC heavy- and medium-duty pickups is driving us to find ways to build more Duramax diesel engines,” said Gerald Johnson, vice president of GMC Global Manufacturing — and the new Brookville plant will play a key role in this.

Engine blocks and heads manufactured at this new plant will be sent to the DMAX plant in nearby Moraine that manufactures 6.6-liter diesel engines. These engines will then go to Flint, Michigan, where they will be installed in GMC Sierra and Chevy Silverado HD trucks.

The Moraine plant, which employs more than 800 people, has assembled more than 2 million diesel engines in the last 20 years. Thanks to GM’s new HD truck models, demand is likely to keep growing, and the presence of the Brookville plant should help ease the pressure.

GM has already consolidated HD truck manufacturing in Flint, adding 1,000 new jobs and preparing to increase production by up to 40,000 units a year.

Last week’s Brookville announcement is welcome news for Ohio, which is still reeling from the recent loss of GM’s Lordstown assembly plant that assembled the now-discontinued Chevrolet Cruze sedan. Overall, GM still employs more than 4,800 people in the state and has invested over $2 billion there over the past 10 years.
