GMC Sierra All Terrain HD Concept: Diesel-Powered Off-Road Awesome
The GMC Sierra All-Terrain HD Concept's a badass, no doubt. It's big. It's macho. It's American. And unlike the Ford Raptor or Ram Power Wagon, you can get it with a diesel engine.
Pointedly named, the All Terrain HD concept starts life as a 2011 Sierra HD 4WD chassis with the Duramax 6.6-liter turbodiesel V8 mated to an Allison 1000 six-speed tranny. The combination produces a respectable 397 hp and a stump-pullin' 765 lb-ft of torque. Already a capable platform, GMC made it wider (73-inch track), taller (21.1-inch ground clearance), and tougher.
The suspension setup's designed for serious off-roading, with a three-inch lift, large skid plates and special Fox off-road shocks created for the All Terrain HD with visible remote fluid reservoirs designed to provide better handling and rebound. There's also an electronic disconnect for the front stabilizer bar should you find yourself climbing over a rocky surface.
Assuming you've got all this "go" it probably doesn't hurt to have a little "show." It looks macho, like a regular Sierra HD using the kind of medication typically prescribed for horses. This is helped by the crew-cab/short-bed construction and the 35-inch BFGoodrich KM2 "mud terrain" tires sitting on 20-inch machined aluminum wheels.
We expect it'll be built — but it probably should be a Chevy given the off-road truck heritage the brand already has. They worked with Fox Shocks, who tell us it'll be like the Raptor, but with even more power and capability. Yes, please.
