DAYTON, Ohio - General Motors Corp. (GM) announced today an investment of $69 million in its DMAX plant in Moraine to manufacture a new Duramax 6.6-liter V-8 turbo diesel engine that will meet stringent emissions standards in 2010. DMAX Limited is a joint venture between GM and Isuzu Motors Limited and was established as a diesel engine company in 1998. The investment includes renovations to the plant, new machinery and tooling to support manufacturing of the new diesel engine. Renovations are expected to begin immediately.
As a result of the investment, the DMAX plant will retain over 1,000 jobs. GM is committed to continuing to reduce fuel consumption and emissions and the 2010 Duramax diesel is an integral part of that transformation. GM first introduced the Duramax diesel in the U.S. in the 2001 model year, and since then customer enthusiasm for this heavy-duty diesel has been outstanding. In fact, GM's heavy-duty pickup truck market share has jumped nearly tenfold in the seven years that Duramax engines have been offered. The award-winning Duramax 6.6-liter V-8 is a four-valve high pressure common rail direct injection diesel currently equipped with a diesel particulate filter to meet the stringent 2007 emissions requirements. Available in GM's Chevrolet Silverado and GMC Sierra heavy-duty pickups, the engine delivers a segment-leading 365 horsepower and 660 lb.-ft. of torque. It is also offered with increased power and torque for the Chevy Kodiak and GMC TopKick medium-duty applications. Versions are available with 300 horsepower and 520 lb.-ft of torque, as well as a new 330-horsepower option with 620 lb.-ft. of torque. The Duramax is also available in GM's full-size vans, Chevrolet Express and GMC Savana.The 2010 model year 6.6-liter V-8 Duramax diesel will use a selective catalytic reduction NOx after-treatment system with a diesel particulate filter to help achieve the 2010 Tier 2 Bin 5 and LEV 2 emissions standards, and it will be compliant in all 50 states. In the DMAX joint venture with Isuzu Motors Ltd., GM owns 60 percent and Isuzu 40 percent. The 584,000-square foot DMAX plant employs 1,195 hourly and salaried employees with annual production near 200,000 engines.
