X Marks the Spot: GMC Reveals Sierra All Terrain X Special EditionPosted in News on January 26, 2016
GMC pulled the wraps off its new Sierra special edition, the All Terrain X. Starting with the relatively capable Sierra All Terrain, that extra letter adds a few functional upgrades to one of our favorite fullsize trucks.
Foremost, GMC product planners ditched the standard All Terrain’s Goodyear Wrangler SR-A tires in favor of some Wrangler DuraTrac MTs. The more aggressive tires will surely imbue the X with some added security and stability off-road, fitting for the truck’s mission. The other dynamic update is a new, freer-flowing exhaust system, bumping the 5.3L V-8’s horsepower rating from 355 to 365 while adding a more aggressive tone.
Other updates include LED headlights, body-color door handles and styling accents, and black exterior mirrors, window moldings, and B-pillars. A bed-mounted sport bar, seemingly cribbed from the smaller Chevrolet Colorado Z71 Trail Boss, provides a mounting point for an accessory LED off-road lighting package. The 18-inch aluminum wheels are painted with an X-specific black motif. The All Terrain X will be an option package on the Sierra SLT crew cab with the short cargo box, meaning it will be fairly well equipped with GMC-trademark luxury features.
As with the aforementioned Trail Boss, suspension settings remain the same as on lesser models. Suffice it to say, buyers of the All Terrain X shouldn’t expect Ford Raptor (or even Toyota TRD Pro) levels of off-road performance from their Sierra. However, the tires alone will add a measure of off-road confidence and styling verve, and we bet the Sierra’s small-block V-8 will sound great bellowing from the new exhaust system. GMC hasn’t announced pricing on the truck, but if it echoes the pricing schemes of its Chevy Silverado and Colorado off-road packages, don’t plan on it costing much more than the standard All Terrain.
According to GMC, the All Terrain X should hit dealers in a few months, so prospective buyers should start clearing garage space now. Spring is just around the corner, after all.
