Editor's note: The Duramax engine's basic OHV layout with four valves per-cylinder has remained unchanged since 2001. An earlier version of this story contained an inaccurate description of the engine.
General Motors’ powertrain division will be supplying the engine for the successor to the Army’s Humvee -- a deal that could see GM deliver as many as 55,000 diesel V-8 engines.
The new Joint Light Tactical Vehicle, to be built by Wisconsin-based Oshkosh Defense LLC, will be powered by a military specification version of the Duramax turbodiesel V-8 used in GM’s heavy-duty pickups. It will also use a transmission made by Allison Transmission LLC, a company formerly owned by GM.
Jennifer Christiansen, vice president of business development operations for Oshkosh, said the company evaluated several engines before choosing the Duramax V-8.
