GM reveals GMC Sierra All Terrain HD concept prior to 2011 NAIAS
One look at the photo provided by media.gm.com and you immediately see it is highlighted by a bold exterior design, enhanced all-terrain suspension and premium details expected of a GMC – all designed to enable greater access to off-road destinations. Moreover, large fender flares stretch away from the body to cover the 35-inch-tall BFGoodrich tires.
According to the release, the new 2011 Sierra HD underpins the All Terrain HD concept, with a modified, production-based 4WD chassis and the Duramax diesel/Allison 1000 six-speed powertrain. The enhanced suspension and unique body dimensions, including increased ground clearance and wider track, as well as greater approach/departure angles, deliver off-road capability while maintaining HD levels of payload and trailering capacity.
Lisa Hutchinson, GMC product marketing director, said, “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. 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.”
From every angle, the All Terrain HD indeed looks the part of a dedicated off-road performer, with bold, accentuated features complemented by a wide stance and tall profile.
