GM-Isuzu JV DMAX invests $60 million in Ohio diesel engine plant

The GM-Isuzu joint venture DMAX, Ltd. will invest $60 million in its Ohio diesel engine plant to make design changes that meet future emissions requirements. Established in 1998, DMAX has produced almost 1.6 million engines since opening in 2000. GM owns 60% and Isuzu owns 40% of the venture that makes the Duramax diesel for heavy-duty trucks.

DMAX, Ltd. has invested $760 million in the DMAX facility since 2000.

DMAX is home to the Duramax 6.6L Turbo Diesel engine used in the Chevrolet Silverado and GMC Sierra. The current Duramax is SAE-certified at 397 horsepower (296 kW) at 3,000 rpm and 765 lb-ft of torque (1,037 N·m) at a low 1,600 rpm.

All Duramax engines include a high-pressure (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 vans.



Sad thing is anymore standards will be the end of the light duty diesel as they sit it becomes a issue of what technology is left. The current regulations are extremely strict and require very expensive parts plus the cost of the truck including the poor fuel economy. I personally know 12-15 people who would love to get 18mpg on the highway again with the current trucks they have like the predecessor 06-07 lbz Duramax.
