Guess Which V8 Will Power The Army's New Oshkosh JLTV?


Heavy duty military action calls for a heavy duty American engine.

A couple of days ago, we told you about the US Army and Marine Corp's awesome choice as it finally named the replacement for its aging Humvee. With $30 billion about to be spent on this tactical vehicle, the Oshkosh Joint Light Tactical Vehicle, we were to curious to find out exactly how this go-anywhere, do-anything vehicle would be specced out. As it turns out, the engine that will power these battlefield offroaders, at least in the first production run of 17,000 vehicles, will be General Motors Powertrain Division's Duramax V8 diesel.

That's right, the same engine that is found under the hood of GMs heavy duty version trucks like the GMC Sierra and Chevrolet Silverado will be powering our troops through all corners of the world in the new JLTV. Assuming the first production run goes smoothly and Oshkosh gets the green light for mass production in a couple of years, this could mean 55,000 engines ordered from GM over the next years. Though no spec has been released for the military version of the engine, Chevy and GMC's civilian models are rated at 397 horsepower and 765 lb-ft of torque.
