Being the third model after Canyon and Sierra 1500, the 2017 Sierra HD All Terrain X limited edition has been built upon the Sierra 2500HD crew cab 4WD and packs a range of features including 18-inch black-painted aluminum wheels; Goodyear Duratrac MT-rated tires; premium package of monochromatic exterior trim and special equipment; and a range of GMC’s latest technologies.
Additional All Terrain equipment include a spray-on bedliner, Front and Rear Park Assist, the Z71 off-road suspension package, underbody shield, heated steering wheel and all-weather floor liners. The Eaton automatic locking rear differential is also standard.
The highlight of the 2017 Sierra HD All Terrain X can be pegged as the is Duramax 6.6L V-8 turbo-diesel that delivers a segment-topping SAE-certified 445 horsepower and 910 lb.-ft. of torque.

“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. “And with the new, available Duramax 6.6L, this truck more than matches its bold good looks with true professional-grade capability.”
