Last month, GMC introduced the first-ever GMC Sierra Denali Ultimate and GMC Sierra AT4X as new models in its lineup of the refreshed 2022 GMC Sierra 1500 pickup truck. In its related reveal video, the automaker noted that over half of GMC AT4 buyers are new to the brand.
“The first-ever Sierra AT4X delivers extreme off-road capability in a rugged, yet ultra-premium package,” the host of the early 16-minute video – actor Will Arnett – says while introducing the new model. “The AT4X builds upon the success of the wildly popular AT4, which is attracting new and younger customers to GMC. In fact, over half of AT4 buyers are new to the brand.”
It is fitting, then, for GMC to launch the all-new 2022 GMC Sierra ATX4, taking the brand’s off-road-capable AT4 pickup truck to the next level as GMC’s equivalent to the new 2022 Chevy Silverado ZR2.
The automaker also took its luxury pickup truck to the next level with the all-new 2022 GMC Sierra Denali Ultimate.
AT4 is a GMC sub-brand of off-road-oriented vehicles with applications for the entire GMC lineup – except for the Savana utility van – including the Sierra 1500, Sierra HD, Canyon pickup truck; Yukon SUV; and Acadia and Terrain crossovers.
AT4 was created as a unique persona that offers credible capability while still providing premium everyday comforts. AT4 variants distinctively combine off-road capability, innovative technology and bold design, along with GMC’s premium refinement to practically complement an authentic outdoor lifestyle. Core AT4 design includes premium rugged exterior details, featuring black chrome grille, fog light surrounds and rear appliques, as well as unique authentic aluminum interior decor and premium fabric colors.
The equipment differs slightly from model-to-model, but all AT4 variants feature re-tuned off-road suspension, underbody skid plates and off-road tires, among other equipment. The Canyon AT4, for example, adds the following equipment:
- 31-inch Goodyear Wrangler DuraTrac tires and 17-inch aluminum wheels
- Off-road tuned suspension with Advanced Hill Descent Control System
- Eaton G80 Rear Automatic Locking Differential
- Transfer case skid plate
Notably, 2019 GMC Sierra 1500 launched the AT4 sub-brand, replacing the All Terrain for models that offered such a trim level, which include the Sierra 1500, Canyon, and Acadia.
The GMC Sierra AT4X is the first of other AT4X models to come, like the Canyon AT4X.
The 2022 GMC Sierra AT4X 1500 comes equipped with unique Multimatic DSSV spool-valve dampers – the same as the ones used on the Chevy 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 regular 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.
Even bigger news than the two new models of the refreshed 2022 GMC Sierra is that SLE trim levels and above (Elevation, SLT, AT4, Denali) will receive a completely overhauled cabin. The new interior addresses criticisms levied against the pickup since the introduction of the 2019 model year, while also incorporating a wealth of new technologies including the GM Super Cruise highway drive assist system.
Highlights here include an all-new 13.4-inch infotainment screen and 12.3-inch digital instrument cluster, plus a new center console, Electronic Precision Shift for models with front bucket seats (column shift is available for models with a front bench seat), and standard power-adjustable steering column for uplevel trims. Further tech highlights include built-in Google compatibility, with Google Maps even providing Super Cruise-enabled routes for those models equipped with the semi-autonomous drive system.
The cabin space in the new GMC Sierra AT4X 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 1500 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.
