One Serious Off-Roader

2012 GMC Sierra All Terrain HD Concept

GMC is known for making the world's toughest trucks, SUVs, and Crossovers. They are known at being "Professional Grade" at whatever they do. When I saw this pic, I knew for sure that they were widening the gap in American Toughness. This is the 2012 GMC Sierra All Terrain HD Concept. From the face of it, you really can't tell that it's a Sierra. But, from the rear,

you may spot the common Sierra tail lamps. This truck looks absolutely rugged. Look at those tires! I bet this truck could handle just about anything. In fact, the Sierra's twin brother, the Chevy Silverado HD just won the Motor Trend Truck of the year for it's levels of toughness. But anyway, under the hood of this tough beast is a 6.6-liter Duramax Diesel V8 engine producing 397 horsepower with a catastrophic 756 lb.-ft. of torque! This truck could bump start a Boeing 747! This engine is connected to a 6-speed automatic transmission sending power to all 4 rugged wheels. The wheels themselves are 20-inches. The tires are heavy-duty 35-inch BFGoodrich KM2 Mud Terrain Tires. This truck could even compete with the popular SVT Raptor thanks to it's Fox Racing off-road shocks. This truck remains a concept model, but may lead to a redesigned GMC Sierra and Chevy Silverado. Look for this truck to make it's debut next month in Detroit at the North American Auto Show.
