GM-Isuzu DMAX plant builds 1,500,000th Duramax diesel engine image

General Motors announced the production of its 1,500,000th Duramax 6.6L diesel engine at its DMAX Ltd. joint venture with Isuzu Motors Ltd.

Established in 1998, DMAX Ltd. employs 517 workers in its 584,000 square-foot facility.

GM introduced the Duramax diesel in the United States in its 2001 model year, with the engine being fitted to models such as the Chevrolet Silverado HD and GMC Sierra HD pickup trucks as well as the full-size Chevrolet Express and GMC Savana vans. The 6.6-liter diesel engine delivers 397 horsepower at 3,000 rpm and 765 lb.-ft. (1037 Nm) of torque from as low as 1,600 rpm.

The Duramax 6.6-liter V8 engine is a four-valve high pressure common rail direct injection diesel currently equipped with a diesel particulate filter to meet current stringent emissions requirements.

“Duramax has become a great success story and is a world-class engine with superior quality, industry-leading horsepower and competitive fuel economy,” said Betty Wessel, DMAX Chief Financial Officer. DMAX CEO, Maho Mitsuya, said the milestone demonstrates the productivity of the employees and the joint partnership between GM, Isuzu and the IUE-CWA union.

“This is a significant achievement for our facility and our employees here at DMAX. We’re committed to building quality into every engine – whether it’s our first or our 1,500,000th,” Mitsuya said.
