If the competition between American car manufacturers to create the biggest, meanest, strongest trucks never comes to an end, we might just be happy forever. And from the looks of things, it doesn’t seem to be letting up anytime soon – as GMC has just announced their newest entry in the brand’s X series: the Sierra HD All Terrain X.
This beefy pickup, which is the most off-road-capable vehicle in the Sierra HD lineup and comes in the Sierra 2500HD crew cab 4WD layout, is being offered in one of two formats. The standard is equipped with a 6.0L V-8 engine and is impressive on its own. But the second is fitted with GMC’s all-new, next-generation Duramax 6.6L V-8 turbo-diesel. This new engine boasts an impressive SAE-certified 445 horsepower and 910 foot-pounds of torque. But it doesn’t stop there. It also features 18-inch black aluminum wheels, front and rear park assist, a body-color grille surround with All Terrain insert, a Z71 off-road suspension package, an Eaton automatic locking rear differential, and a number of other impressive physical and technological features. No word yet on what the price will be, but you can expect to see this monster for sale early next year. [Purchase]
