Joining the likes of the Canyon and Sierra 1500 this fall as the third model in GMC’s limited-edition All Terrain X series, the Sierra HD All Terrain X is said to be the most off-road-capable truck in the Sierra HD lineup.

 

 

Aside from its 6.0-liter petrol-powered V8, the Sierra 2500HD crew cab 4WD will also be available with the all-new next-generation Duramax 6.6-liter V8 turbo-diesel, sending 445 HP (332 kW) and 910 lb-ft (1,234 Nm) to all four wheels.

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