For the 2011 Detroit Auto Show, Gmc Sierra has unveiled new truck series it’s the 2011 GMC Sierra All Terrain HD Concept. This concept is a study into “heavy-duty truck capability combined with greater off-road versatility.” While The Dodge Ramrunner and Ford F-150 SVT Raptor both held prominent spots in their respective booths at the 2011 Detroit Auto Show, the Sierra All-Terrain Concept was tucked away in a corner all by its lonesome.
Lisa Hutchinson, GMC product marketing director said “The capability-enhancing attributes of the Sierra All Terrain HD build on the already outstanding capabilities offered in the all-new production Sierra HD trucks,” and also said “Although it is strictly a concept, it is a pretty realistic one.”
For the power perfomance, GMC Sierra All Terrain HD Concepts has featured a 6.6L Duramax turb0-diesel engine making 397-hp and 765 lb-ft of torque. Mated to a Allison 1000 six-speed automatic, the GMC Sierra All Terrain HD Concept has a Maximum towing capacity (fifth-wheel hitch) of 15,600 lbs. It’s also has featured a 5-foot, eight-inch Crew Cab/short box body configuration that supports a wheels-at-the-corners proportion. With a shorter overall length than production Sierra HD models, the concept’s dimensions contribute to greater departure angles.
2011 GMC Sierra All Terrain HD Concept on the off-reading gear has include a wider 73-unch track for extra stability, 3-inches of ground clearance, custom front upper and lower control arms, front and rear jounce shocks, electronic front stabilizer bar and 35-inch-tall BFGoodrich KM2 “mud terrain” tires mounted on 20-inch machined aluminum wheels.
