GMC Sierra All-Terrain HD Concept Unveiled for Columbia Drivers

The 2011 GMC Sierra All-Terrain HD concept to be unveiled at the North American International Auto Show next month.

Jim Hudson GMC, the oldest Columbia GMC dealer, is proud to announce the unveiling of the GMC Sierra All-Terrain HD concept pickup truck.  Unveiled on GMC’s media web site, the Sierra will be on display next month at the North American International Auto Show in Detroit.

The Sierra All-Terrain HD is based on the new 2011 GMC Sierra 2500HD for sale in Columbia, South Carolina, sharing the production 6.6L Duramax diesel V8 engine mated to a six-speed Allison 1000 transmission.  This Duramax engine is 11% more fuel-efficient than the outgoing engine used in the 2010 Sierra heavy duty trucks and reduces NOx emissions by 63%.  Rated at 397 horsepower and a monstrous 765 pound-feet of torque, the engine also features exhaust braking to save the brakes from excess wear on downhill grades, a feature also available on the production Sierra 2500HD.

The standard bed was jettisoned for a 5’8″ long bed, closer to the size found on a light duty GMC Sierra 1500 crew cab.  Opting for this bed pushes the wheels out toward the corners for improved approach and departure angles.  Sporting a composite bedliner designed in the style of a circuit board, the bed features locking storage in the side rails, LED flood lighting inside the bed, and connectivity including an onboard air compressor and a 110V household-style power outlet.  Access to the bed is improved by motorized power-retractable assist steps on the side of the bed.

Off-road prowess abounds in the Sierra All-Terrain HD, with the track widened to 73 inches for stability and the entire truck raised for three extra inches of ground clearance. 20-inch machined aluminum wheels are wrapped in 35-inch BFGoodrich KM2 mud-terrain tires for grip in practically anything, while specially-built Fox off-road shocks featuring remote reservoirs integrated in the wheel house liners help to keep the suspension in check alongside front and rear jounce shocks.  For extra protection, a composite underbody structure keeps the Sierra All-Terrain HD from taking the terrain with it.  The driver can press a single button to disconnect the front stabilizer bar, allowing more suspension travel while on rocky terrain.

The interior matches the exterior aesthetic, with premium appointments and increased functionality, including enhanced lighting. It conveys solidity and precision, blending accent details such as stainless steel mesh and satin chrome with an amplified expression of the All Terrain’s premium features. Two-tone dark gray leather seats, matched with embossed carbon fiber-style leather on the seating surfaces, have red contrast stitching.   Additional leather-wrapped interior features include the steering wheel, instrument panel and center console.

A new navigation radio is also featured on the Sierra All Terrain HD concept and previews future radios to be offered in GMC vehicles. An integrated 80-gig hard drive contains map data for the navigation system. It eliminates the need for a map disc and provides greater storage of music from portable devices. It also features DVR-style “time lapse playback,” which allows up to 20 minutes of recording/playback from the AM/FM/XM radio stations.
