X Marks the Spot: GMC Reveals Sierra All Terrain X Special Edition

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.
