GMC Previews Sierra All Terrain HD Concept Ahead of Detroit Show

General Motors will be presenting an ultra-tough concept study based on the four-door 2011 GMC Sierra HD pickup truck at the rapidly approaching Detroit Motor Show in mid-January. The GMC Sierra All Terrain HD study is highlighted by its rough n' tough exterior design and enhanced all-road capability.

Shorter in overall length than production Sierra HD models, the concept boasts a unique five-foot, eight-inch Crew Cab/short box body configuration with the wheels pushed to corners of the vehicle.

It also features a wider, 73-inch (1,853 mm) track for greater stability and approximately 3 inches (76 mm) greater ground clearance for a total of 21.1 inches (536 mm) at the rockers and 11.8 inches (300 mm) at the skid plates.
