The Duramax I6 engine is a diesel engine available in select models of General Motors light-duty trucks and SUVs. Applications include the Chevrolet Silverado/GMC Sierra 1500, Chevrolet Suburban/GMC Yukon XL, Chevrolet Tahoe/GMC Yukon, and Cadillac Escalade (both short wheelbase and ESV). The engine was developed together with Opel, who are manufacturing three- and four-cylinder versions displacing 1.5 and 2.0 liters, using the same engine architecture.

    Engine details

    [edit]

    The engine's timing components are located at the rear of the engine, and feature timing chains to drive the camshafts and high pressure fuel pump, and a wet belt to drive the oil pump.[1]

    Most of the development and engineering work for the LM2 Duramax, as well as primary calibration took place in Turin, Italy.[2][3] The engine is being produced at Flint Engine Operations.[4] A test by Car and Driver showed 40 MPG is possible when hypermiling.[5]
