Looking to compete with the likes of the RAM Power Wagon and Ford F-150 Raptor, GMC has announced the third member of its limited-edition All-Terrain X series, which comes in the form of the 2017 Sierra HD All Terrain X.


Confused by Car Terms? Here’s a clear definition of what torque really means


Coming standard with the Z71 off-road suspension and LT275/65R18 Goodyear Duratrac MT-rated tires, GM says the new Sierra HD All-Terrain X is the most off-road-capable truck currently offered by the American automaker. The other two All-Terrain X models available are the GMC Canyon All Terrain X and Sierra 1500 All Terrain X.

The 2017 Sierra HD All Terrain X will only be available in crew cab format and with four-wheel drive. However, consumers can choose between a 6.0-liter gas-powered V8 engine and the new 6.6-liter turbo-diesel V8 motor. In case you haven’t already heard, that new turbo-diesel is good for 445 horsepower and 910 lb-ft of torque.

The exterior of the new Sierra HD All Terrain X will come standard with unique 18-inch black painted aluminum wheels, LED lamps, and a distinctive body-color grille surround with an All Terrain insert.

“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 Vice President of GMC Sales and Marketing Duncan Aldred. “And with the new, available Duramax 6.6L, this truck more than matches its bold good looks with true professional-grade capability.”

Engineers were not conservative either when it came to designing the interior for the newest ALL Terrain X model. That’s because the cabin comes standard with leather-appointed seats, wireless charging, heated front seats, and a heated steering wheel. In addition, this new GMC truck also comes with a remote-locking tailgate, Teen Driver technology, and the GMC IntelliLink system with an 8-inch color touchscreen.

Consumers who are interested in finding out how much this limited-edition truck will cost have to wait since the company still has not disclosed pricing details.
