GM is celebrating a milestone today: the production of the 1.5 million Duramax diesel engine at its DMAX  facility.

The Duramax breathes life into the Chevy Silverado HD, GMC Sierra HD, Chevrolet Express and GMC Savana cargo vans. It puts out 397 hp at 3,000 rpm and 765 lb-ft of torque at 1,600 rpm. To achieve these numbers, the motor uses a four-valve high pressure common rail direct injection system.

The engine is a result of a joint venture between General Motors and Isuzu Motors Ltd. “This is a significant achievement for our facility and our employees here at DMAX,” said DMAX CEO Maho Mitsuya. “We’re committed to building quality into every engine – whether it’s our first or our 1,500,000.”
