With pickup trucks currently a hot commodity, the plant that supplies Duramax diesel engines for the Chevrolet Silverado and GMC Sierra recently announced an $60 million investment to help to make design changes that will help engines meet emissions requirements in the future.

The plant, located in Moraine, Ohio (just outside of Dayton), was established in 1998, and opened in 2000. DMAX, Ltd. is a joint venture between General Motors and Isuzu, and has produced almost 1.6 million engines since it opened. The $60 million comes on top of the $760 million invested in the plant thus far. Approximately 500 jobs will be retained at the plant.

The investment “demonstrates GM’s commitment to continuously invest in technologies that reduce the impact of our vehicles on the environment, while maintaining performance attributes required by customers in the areas of towing and hauling loads,” said GM North America Manufacturing Manager Christine Sitek.

The current Duramax is SAE certified at 397 horsepower (296 kW) at 3,000 rpm and 765 lbs-ft of torque (1,037 Nm) at a low 1,600 rpm. All Duramax engines include a high-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions. The Duramax is also available in the Chevrolet Express and GMC Savana full-size van.
