The 2022 GMC Sierra 1500 introduces two new trim levels to the Light Duty Sierra pickup lineup, including the luxurious Sierra Denali Ultimate, as well as the rough-and-ready Sierra AT4X, the latter of which ushers in GMC’s equivalent to the new 2022 Chevy Silverado ZR2 as a more-capable off-roading model variant.
GM Authority was the first to report on the new 2022 GMC Sierra AT4X. Back in July, GM Authority exclusively announced that the AT4X was indeed slated to arrive with the 2022-model-year refresh, slotting in above the existing GMC Sierra AT4 with regard to the existing model lineup. Then last month, GM Authority provided a full rundown on expectations for the new AT4X pickup.
The keep it shiny side up, the 2022 Sierra AT4X is equipped with unique Multimatic DSSV spool-valve dampers, similar to the Colorado ZR2 and Silverado ZR2. These dampers are matched with unique springs, the combination of which increase the maximum front suspension travel by 50mm and rear suspension travel by 25mm, as compared to the non-X GMC Sierra AT4.
Under the hood, the 2022 Sierra AT4X runs the naturally aspirated 6.2L V8 L87 gasoline engine as standard, with output rated at 420 horsepower and 460 pound-feet of torque. Output is routed through a 10-speed automatic transmission and two-speed transfer case, with multiple driving modes on tap, such as Terrain Mode for one-pedal rock crawling capabilities.
The drivetrain also comes with front and rear e-locking differentials, while unique chassis and suspension tuning make the most of onboard components. The greasy bits are protected by a unique steel transfer case skid plate. Payload capacity is set at 1,420 pounds, while the trailering rating is 8,900 pounds.
Outside, the 2022 Sierra AT4X rolls on a set of black 18-inch wheels, which are wrapped in 265/70R18 Goodyear Wrangler DuraTrac Mud-Terrain tires. The new AT4X is also offered with a rocker guard accessory.
The cabin space is decked out with a unique “Obsidian Rush” interior treatment, which incorporates premium leather upholstery with white piping and red stitching. The luxurious leather is complemented by Vanta ash wood trim, while 16-way power adjustable and massaging front seats, a microsuede headliner, 15-inch Head-Up Display, and 12-speaker Bose sound system keep it comfortable and connected.
Pricing for the new 2022 Sierra AT4X starts at $74,995. Deliveries for the refreshed 2022 GMC Sierra 1500 are expected to ramp up in the first quarter of the 2022 calendar year.
