2016 GMC Sierra All Terrain X: A Stylish, Monochromatic, Off-Roading Option

January 27, 2016

General Motors' GMC brand is rolling out a slick new version of its Sierra pickup that should appeal to style-conscious off-roaders everywhere: the 2016 GMC Sierra All Terrain X.

Thanks to a bed-mounted support bar -- designed to support an LED lighting package -- and its Sierra-branded side panels, the limited-edition All Terrain X looks a bit like the discontinued Chevrolet Avalanche. (Thought its bed doesn't convert in the way that the Avalanche's did.)

Other exterior touches include door handles and side moldings that match the truck's body color; black side-view mirrors; a black B-pillar; sport side steps; and high-performance LED headlamps.

The truck's grille features a body-color surround with tinted chrome accents, and the front and rear bumpers are both matched to the body color. The 18x8.5-inch black aluminum wheels are fitted with 265/65R18SL Mud-Terrain-rated Goodyear Wrangler DuraTrac MT tires, which are perfect for off-roading through mud, dirt, and gravel in any kind of weather.  

On the performance front, the All Terrain X's 5.3L EcoTec V-8 engine offers 365 horsepower (up from the normal 355), trumpeted by an "aggressive" exhaust note. The truck's 4WD drivetrain comes with an Eaton locking rear differential Z71 Off-Road suspension package, including Rancho monotube shocks, a high-capacity air cleaner, and Hill Descent Control.

Behind the wheel, drivers will enjoy features like Rear Park Assist and an inclinometer, found on the driver's info center. The instrument cluster is branded with GMC's All-Terrain logo.

Though it's shown above in Onyx Black, the Sierra All Terrain X will also be offered in Summit White, Stone Blue Metallic, Iridium Metallic, Crimson Red Tintcoat, and Light Steel Gray Metallic.

The GMC Sierra All Terrain X will be offered as an option on 2016 Sierra 1500 4WD crew cab/short box models equipped with the SLT trim. The All Terrain X debuts this spring. Pricing hasn't yet been announced.
