General Motors is spending $69 million to renovate its DMAX plant in Ohio in preparation for a Duramax 6.6-liter V-8 turbo diesel engine that will meet 2010 emissions standards. The renovations, which include new machinery and tooling to support the new engine.
The new Duramax 6.6-liter V-8 turbo diesel will jump through the 2010 CAFE hoops by using a selective catalytic reduction NOx after-treatment system and a diesel particulate filter. This will help it pass the 2010 Tier 2 Bin 5 standards and achieve LEV 2 emissions status.
The Duramax 6.6-liter V-8 currently used in the Chevy Silverado and GMC Sierra heavy-duty pickups produce 365 horsepower and an enormous 660 lb-ft of torque. The engine is also used in the Chevy Express and GMC Savana vans as well as the medium-duty Chevy Kodiak and GMC TopKick. In the seven years that Duramax diesels have been offered, GM says its heavy-duty pickup truck market share has increased almost tenfold.
