The oft-overlooked Sierra All Terrain's off-road suspension and Eaton locking rear differential give it some real trail credentials. The All Terrain X builds on both with cosmetic and performance upgrades. For most owners, the big draw will be the brawnier 5.3-liter V8. Fitted with a performance exhaust, it should deliver a meatier tone, and according to GMC it bumps output up from 355 to 365 horsepower. The other big performance upgrade comes from the tires, knobby Goodyear Wrangler DuraTrac MT mud-terrain-rated things. The tires and their accompanying 18-inch black aluminum wheels are nice touches.
Cool as the All Terrain X might be, it strikes us as an odd strategy for the GMC brand. For one, the trail-ready tires and performance exhaust of the All Terrain X don't seem to fit into the more premium market position that GMC occupies. Moreover, Chevy already has an off-road-oriented pickup in the new Colorado Z71 Trail Boss. Visual upgrades like the black bed-mounted sport bar, LED off-road lights, blacked-out accents, and the 18-inch wheels, the look of the All Terrain X is more in line with the Colorado Trail Boss theme. It's just our two cents, but it seems like attaching the All Terrain X's aesthetic to the Silverado would have been a stronger strategy, and would give Colorado buyers a larger off-road-focused truck to aspire to.
