Also available with a 6.0-liter V8 gasoline engine, the limited edition gets an assortment of visual and hardware upgrades.
Following the introduction of the Canyon and Sierra 1500 All Terrain X models, GMC is giving the Sierra 2500HD crew cab 4WD the same treatment with a beefier exterior appearance matched by the enhanced off-road capabilities. To set it apart from the lesser versions, GMC has given the truck an assortment of black accents and a bespoke grille surround featuring the same color as the body: either Black Onyx or Summer White.
It sits on 18-inch black wheels shod in chunky LT275/65R18 Goodyear Duratrac MT-rated tires and comes as standard with the Z71 off-road suspension kit and the Eaton automatic locking rear differential. As you would come to expect from a high-end trim, the Sierra HD’s All Terrain X version offers a plethora of goodies, including four-inch black sport side steps, Front and Rear Park Assist, an underbody shield, and a remote-locking tailgate. It also has LED rear guidance lamps and LED amber clearance lamps, as well as a sport bar mounted in the bed that can accommodate a variety of accessories, including LED driving lamps.
As far as the interior cabin is concerned, the Sierra HD All Terrain X benefits from leather upholstery and heated front seats, while the 8-inch GMC IntelliLink infotainment system is also standard. Rounding off the list of features are the wireless charging capabilities, adjustable pedals, and a remote start function.
Customers get to pick from either the familiar 6.0-liter V8 gasoline engine with 360 hp & 380 lb-ft or the all-new Duramax 6.6-liter V8. The latter is a turbodiesel beast with a whopping 445 horsepower (332 kilowatts) and a mountain-moving 910 pound-feet (1,234 Newton-meters) of torque as seen in the recently introduced 2017 Chevy Silverado HD.
The 2017 GMC Sierra HD All Terrain X debuts today at the Texas Truck Rodeo near Austin and will go on sale later this fall at a yet undisclosed price tag.
