The 2022 Sierra AT4X is GMC's new peak in premium off-roading. This all-new Sierra AT4X is a balanced execution that delivers advanced off-road capability when called upon without compromising the on-road comfort, tech, towing, and payload capability expected from a premium pickup.

Highlights of this all-new Sierra off-roader include: 6.2L V-8 engine and 10-speed automatic transmission; Multimatic DSSV spool-valve dampers, and unique springs that, with the Multimatic dampers, increase maximum front and rear suspension travel by 50 mm and 25 mm, respectively, compared with the standard AT4 suspension. A two-speed transfer case, with selectable modes for different off-road conditions, including Terrain Mode, is standard. The 2022 Sierra AT4X has specific off-road chassis and suspension calibrations, plus 18-inch black wheels with LT265/70R18 Goodyear Wrangler DuraTrac Mud-Terrain tires.

The functional features are complemented with a unique, luxury-focused AT4X Obsidian Rush interior that balances the off-roader's capability with comfort and convenience. The cabin is awash with premium leather, including full-grain leather-wrapped and technical grain leather accents, highlighted with white piping and red stitching.

The interior also features authentic, dark Vanta ash wood trim, 16-way power-adjustable and massaging front seats, a premium microsuede headliner, a 15-inch-diagonal Head-Up Display, power sliding rear window, power sunroof, a 12-speaker Bose Premium Series audio system with Center Point technology.

The Sierra AT4X's payload capability is 1,420 pounds and its trailering rating is 8,900 pounds.
