The Duramax V8 engine is a family of 6.6-liter diesel V8 engines produced by DMAX, a wholly owned subsidiary of General Motors in Moraine, Ohio. The Duramax block and heads are supplied from reliable vendors of General Motors.[vague] This engine was initially installed in 2001 Chevrolet and GMC trucks, and has since become an option in pickups, vans, and medium-duty trucks. In 2006, production at Moraine was reportedly limited to approximately 200,000 engines per year.[2] On May 9, 2007, DMAX announced the production of the 1,000,000th Duramax V8 at its Moraine facility,[2] followed by the 2,000,000th on March 24, 2017.[3]
