In addition to Sierra HD’s renowned strength and capabilities, the new Sierra 2500 HD All Terrain X offers a unique blend of specialized exterior enhancements and off road special equipment.

After introducing the Sierra 1500 All Terrain X full-size pickup and the Canyon All Terrain X small pickup, GMC is now extending the same formula to its heavy-duty pickup family with the new 2017 Sierra HD All Terrain X.



Available on four-wheel drive 2017 Sierra 2500 HD crew cab models in either Black Onyx or Summit White exterior colors, the 2017 Sierra HD All Terrain X package provides a unique, premium mix of specialized exterior trim and off-road special equipment, uniquely paired with GMC’s high-level of refinement and technologies.


All Terrain X’s customized appearance starts with a unique body-color grille surround, which flanks a distinctive grille insert that’s unique to All Terrain. Body color door handles, front and rear bumpers, and bodyside moldings provide a distinctive monochromatic appearance, while black accents, including belt moldings, front bumper skid plate, and B-pillar accents, enhance its bold attitude.


Sierra HD All Terrain X models also include unique eighteen-inch black-painted aluminum wheels – fitted with rugged LT275/65R18 Goodyear Duratrac MT-rated tires – along with four-inch black sport side steps, black heated and power-folding trailering mirrors with integrated turn signals and LED guidance lamps, a spray-on bedliner, and a distinctive black bed-mounted sport bar, which is designed to support available GMC Accessories LED off-road driving lamps.


Inside, the 2017 Sierra 2500 HD All Terrain X also features GMC IntelliLink with an 8-inch-diagonal color touchscreen, Teen Driver, remote-locking tailgate, remote starting system, Rear Vision Camera, adjustable pedals, leather-appointed seats, heated front seats and wireless mobile device charging.


Sierra HD All Terrain X’s strong, bold appearance is matched by equally strong engineering underneath its surface. A 6.0-liter gasoline engine is standard, but the all-new, next-generation 6.6-liter Duramax Diesel turbo-diesel V-8 is also available. More powerful and refined than ever before, this latest Duramax Diesel delivers 445 hp and 910 lb-ft of torque – providing plenty of power to trailer with confidence.


For added confidence off-road, the Sierra HD All Terrain X also includes the Z71 off-road suspension package, which adds front underbody and transfer case skid plates, twin-tube Rancho shocks, hill descent control, and off-road information graphics in the Driver Information Center. An Eaton automatically-locking rear differential is also standard equipment.


Look for the 2017 Sierra HD All Terrain X to arrive at GMC dealers beginning in early 2017.
