The newest of the GMC packages — which, interestingly, can also be ordered in bright white — is for the 2017 Sierra 2500 crew-cab four-wheel-drive model equipped with the all-new, more powerful turbo-diesel 6.6-liter Duramax V-8 and upgraded six-speed Allison 1000 transmission, and it looks sharp.
The new trim package will have the characteristic monochromatic exterior trim, meaning all bumpers, door handles, front bumper skid plate, side molding and grille surrounds can be ordered in either Black Onyx or Summit White. The package will also include black painted aluminum rims, aggressive Duratrac MT tires, power adjustable trailer mirrors, a 4-inch side-step bar, a black sport bar (which you can add accessory spotlights to) and the standard Z71 off-road suspension package.
We recently had the chance to drive a Sierra 1500 All Terrain X (pictured at the very bottom) and found it to be impressively capable in rugged and punishing off-road environments. The knobby mud tires and front skid plate were lifesavers during our backcountry outing. In the half-ton configuration, the Sierra All Terrain X comes equipped with a choice of the 5.3-liter or 6.2-liter gas V-8 (each with the eight-speed transmission) and lists, depending on options, around $55,000 (including destination). With its premium diesel and heavy-duty transmission option, the HD All Terrain X is likely to start well more than $60,000. But we love the looks.
Expect Chevy to announce its own new limited-edition trim package soon.
