The Brookville DMAX plant was designed to operate concurrently with the original DMAX plant in Moraine, sending the established plant machined engine components. Previous reports estimated that the Brookville DMAX plant would start with about 100 employees.
From the larger Moraine plant, finished diesel engines go to a GM plant in Flint, Mich., where the engines are built into the new Chevrolet Silverado and GMC Sierra HD (heavy duty) trucks.
Since 1998, DMAX has been a 60-40 joint venture of GM and Isuzu, with GM being the majority owner. The Moraine plant has built more than 2 million engines since 1999.
