The new 2017 GMC Sierra HD All Terrain X combines heavy-duty capabilities with incredible off-road performance. Buyers will love its trail-ready abilities matched with the Sierra’s ever-present sophistication.
This is the third model in GMC’s All Terrain X series and joins the Canyon and Sierra 1500 models that are already available.
“The new Sierra HD All Terrain X’s powerful attitude reflects a popular trend in very capable off-road trucks, executed with a range-topping level of refinement — a combination of attributes GMC has cultivated for years,” said Duncan Aldred, vice president of GMC Sales and Marketing.
Powered by an all-new, next-generation Duramax 6.6-liter V8 turbo-diesel and with standard four-wheel drive, the Sierra HD All Terrain X won’t let anything stand in its way. It delivers 445 horsepower and an incredible 910 lb-ft of torque.
In addition to its incredible power, this special truck comes with 18-inch black-painted aluminum wheels, Goodyear Duratrac MT-rated off-road tires, 4-inch black sport side steps, black sport bar, a unique body-color grille surround, body-color door handles and side moldings, a spray-on bedliner, and more. Buyers can choose between Black Onyx and Summit White exterior colors.
This incredible truck will be available this fall and will be ready to tackle whatever adventures come your way.
