GMC unleashed wilder Sierra 2500 HD All Terrain X with 910 lb-ft of torque

Article by Christian A., on November 18, 2016

After introducing the Sierra 1500 and Canyon All Terrain X pickups, GMC has decided to give the Sierra 4x4 2500 HD a variety of upgrades. And for that, we can expect GMC’s crew cab to have the new underbody plate, off-road suspension kit, leather seats, heated steering wheel, park assist among many others. The 2017 SLT Crew cab will be offered in All-Terrain X and four wheel drive. Seeing how it goes with the Sierra 1500, the strong-featured X package can give the 2500 HD pickup the same rugged appeal.

The exterior modifications and hardware enhancements will significantly improve the crew cab’s overall looks and off-road performance. Aside from the black accents, GMC added a bespoke grille surround in either Summer White or Black Onyx body paint. All these features are considered to easily distinguish the Sierra 2500 limited edition from its inferior counterparts.

Moreover, the 2018 Sierra HD All Terrain X features an 18-inch black set of wheels. The tyres, which come from Goodyear, are the heavy duty LT275/65R18. Other standard equipment that comes with the package consists of Eaton automatic locking rear differential and Z71’s off-road suspension system.

By all means, the limited edition Sierra HD All Terrain X is also equipped with high-end accessories. Among the highlights are the LED lights, remote locking tailgate, under body shield and sport edition bed bar and side steps.

When it comes to the cabin, the Sierra HD All Terrain X will be featuring the remote start function, adjustable pedals, wireless charging, 8-inch Intellilink infotainment system and heated front seats with leather upholstery.

The meaner-looking pickup can be availed either in the latest 6.6 L V8 Duramax or the standard 6 L V8 gasoline. An impressive piece of work, the Duramax is a turbodiesel engine that boasts up to 445hp and 910 lb-ft of torque. Nevertheless, the regular engine can produce up to 360hp and 380 lb-ft for its output.

The Sierra HD All Terrain held its debut recently at the Texas Truck Rodeo. As for the price, we don’t know yet how much the new X package costs (for the 2500 HD), but the Sierra 1500 package starts at $4,315. That would serve as our basis for the meantime. GMC is set to bring the 2017 Sierra 2500 HD to the showrooms early next year. The exact cost of the upgrades isn’t available yet unfortunately. It may take a few months before the announcement is made. For now, it’s a good idea to save up.
