GMC revealed its new GMC Sierra All Terrain HD Concept at the 2011 Detroit Auto Show, and honestly to tell you the car made quite a buzz. GMC created this rugged concept to fill the gap in the market between the extremely stylish Ford F-150 SVT Raptor and the simpler Dodge Ram Power Wagon. GMC provided this full photo, giving an in depth look at a possible off-road version of the big truck. GMC also showed styling elements that are expected to appear in its upcoming production model.
The pickup features a combination of the standard Crew Cab from the four-door 2011 Sierra HD with the 5′ 8″ box, which is presently not available on HD models yet. GMC gave the All Terrain concept a special front end with a massive front grille, custom matte-chrome accenting and LED lights. The package also includes a two-inch lift, with Fox Shox and custom control arms.
To boost the off-road capability of the truck, it has been fitted with a sculpted front end that offers increased approach angle and the side steps that are retractable too. A special hard composite has been used to coat the entre undercarriage for maximum durability. The truck is powered by a 6.6-liter Duramax diesel V8 engine that offers 397hp and 765 lb-ft (1037 Nm) of torque to all four wheels, using a six-speed automatic gearbox. The truck features 20-inch 8-lug wheels, which are covered in a set of 35-inch-tall BFGoodrich KM2 'mud terrain' tires.
