GMC Sierra All Terrain

GMC Duramax Powered Off Road Concept


General Motors is considering production of their GMC Sierra All Terrain concept. The 3/4 ton truck is built on the 2011 2500 HD platform and uses the factor production cab, chassis, and powertrain (6.6L Duramax & Allison 1000 combo). Despite the similarities to the production 2500 HD, the All Terrain has a go anywhere attitude supported by an aggressive stance and all the amenities required to tackle the roughest of terrain. A 5.1" shorter wheelbase and 9.2" shorter body allow for improved approach/departure angles. 3" of lift and 35" tall tires give the truck 11.8" of ground clearance, as apposed to the factory 4-wheel drive 2500's 8.2" of ground clearance. The aggressive BF Goodrich Mud Terrains wrap 20" billet wheels, which feature a wider wheel offset for increased stability. To enhance off road capability, suspension travel is controlled by Fox Racing Shox connected to new aluminum upper and lower control arms. And when maximum flexibility is required, the front anti-roll bar can be disconnected electronically.


While the GMC Sierra All Terrain is equipped to handle rough terrain, it retains a respectable 2,700 lb. payload and 15,600 lb. maxium tow capability. There is no mistaking that this truck takes aim at the market that Ford's SVT Raptor currently dominates. If put into production, however, the GMC Sierra All Terrain would likely merge portions of the "All Terrain/Off Road" market with the heavy duty diesel market. The payload and towing capabilities surpass the Raptor, making it a viable choice to consumers who need a truck for work and play. And while the heavy diesel may not allow the truck to be quite as nimble as Ford's Raptor, the engine does offer generous amounts of torque. Ford's Raptor has enjoyed success in a market in which one can argue there is no competition - for now. The GMC Sierra All Terrain is similar to the concept released in Chevrolet trim several years ago, which was a gas powered 1/2 ton. It's obvious that GMC has the resources necessary to roll this concept into production; will they?
