Facility Details

DMAX is a joint venture, 60 percent owned by GM, 40 percent owned by Isuzu Diesel Services of America, Inc. 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 2010 emissions requirements. Available in GM's Chevrolet Silverado and GMC Sierra heavy-duty pickups, the engine delivers a segment-leading 397 horsepower at 3,000 rpm and 765 lb.-ft. of torque at 1,600 rpm – an improvement of 32 horsepower and 105 lb.-ft. of torque over last year’s engine. The Duramax is also available in GM's full-size vans, Chevrolet Express and GMC Savana.

The Duramax History of Durability

With nearly 1.69 million Duramax diesel engines put into operation since its launch in 2000, no other automaker has as much diesel engine development experience for meeting the demands of the heavy-duty truck customer.
