Buyers of GMC’s Sierra lineup of pickups looking for a little extra off-road capability can look forward to the new Sierra All Terrain X. The special edition truck goes on sale this spring, as a 2016 model.

The special edition is based on the latest Sierra 1500 4WD crew cab with SLT trim and the All Terrain package. However, it adds a few extras as part of its “X” treatment. One of these extras is a performance exhaust system that boosts power from the truck’s 5.3-liter V-8 to 365 horsepower, up from the standard 355 hp.

Other extras include the all-black exterior; custom 18-inch aluminum wheels shod with 265/65-size Goodyear Wrangler DuraTrac Mud-Terrain tires; body-colored door handles and side moldings; sports side steps and bed-mounted bar; and custom floor liners. This is on top of all the other goodies that come with the regular All Terrain package, such as the four-wheel-drive system with Eaton locking rear differential and Z71 off-road suspension.

If you’re not a fan of the black, the special edition will also be offered in Summit White, Stone Blue Metallic, Iridium Metallic, Crimson Red Tintcoat and Light Steel Gray Metallic.
