Camp Chevy has sorely lacked a response to Ford’s F-150 SVT Raptor but evidently someone, at least in the concept department, has been listening. Based off the four-door 2011 Sierra HD, the 2011 All Terrain concept is powered by Chevy’s potent 6.6 liter Duramax V8 diesel engine, which is good for 397 horsepower and 765 lb-ft (!) of glorious twist. Three inches of lift and 4″ of width have been added to accommodate the mammoth 35″ BGGoodrich KM2 mud-terrain tires wrapped around 20″ aluminum wheels. Other additions included Fox off-road shocks, satin metal and leather wrapped interior, and stereo upgrades galore. GM has no plans to bring this concept to production, but all we have to say is, “build it and they will come.”
