GMC Sierra All Terrain HD Concept
The GMC Sierra All Terrain HD concept takes the existing Sierra HD platform and enhances it with increased off-road capability. Bold exterior design, an upgraded all-terrain suspension, and a suite of premium features all come together to extend the reach of the Sierra HD. It's powered by the fan favorite Duramax diesel/Allison 1000 six-speed powertrain.
Additional features include a unique, five-foot, eight-inch Crew Cab/short box body configuration that allows for a wheels-at-the-corners proportion, 3 inches (76 mm) of increased ground clearance, wider 73-inch (1,853 mm) track, custom front upper and lower control arms, specially designed Fox off-road shocks, electric front stabilizer bar disconnection, 35-inch-tall BFGoodrich KM2 "mud terrain" tires on 20-inch machined aluminum wheels, and full composite underbody protection for outstanding durability.
"The Sierra All Terrain HD concept takes GMC's outstanding new HD platform to the next level, marries it to the legendary Duramax diesel/Allison transmission, and provides a heavy-duty expression of GMC's premium All Terrain package," said Lisa Hutchinson, GMC product marketing director. "It delivers the exceptional capabilities of the Sierra HD - hauling, towing and performance - and applies them to the toughest driving environments. It's the ultimate professional-grade tool for construction crews, ranchers and adventurers whose activities aren't limited by where the pavement ends."
