GM refreshed the Chevy Silverado 1500 for the 2022 model year, giving its bread-and-butter pickup a bevy of much-asked-for changes. One of the most noteworthy updates to the 2022 Chevy Silverado 1500 is the addition of the Silverado ZR2 to the lineup as the range-topping off-road model. Luckily, the Silverado’s corporate cousin, the GMC Sierra, will also benefit from the existence of the Silverado ZR2 by way of the upcoming 2022 GMC Sierra AT4X – a new off-road-oriented trim that will serve as the range-topper of the Sierra 1500 range.
GM Authority is now outlining what we know and expect from the upcoming Sierra AT4X.
GM Authority was then the first to tell you about the new GMC Sierra AT4X in July, and that the new trim will be tagged with the 4SB equipment group code and will slot above the “regular” GMC Sierra AT4 as a more-capable off-roading rig, much like the Silverado ZR2 is to the Silverado Trail Boss.
This strategy has precedent, as GMC employed a similar strategy in the recent past, back when the AT4 sub-brand was known as All Terrain. At the time, GMC offered the “regular” Sierra AT4 1500, followed by the Sierra All Terrain X 1500 (only for the 2017 and 2018 model years). Neither of those trucks were as well-executed as the AT4 line is today, so it stands to reason that the AT4X will be a product with a lot more substance than the All Terrain X before it.
Features are largely expected to mirror those introduced by the 2022 Chevy Silverado ZR2. For starters, the Sierra AT4X will benefit from a new front end via the upcoming 2022 model year refresh. The AT4X should build on that via a unique lower fascia both in the front and rear, enabling greater approach and departure angles compared to the “regular” AT4. Additionally, the 2022 GMC Sierra AT4X is expected to offer a complete set of underbody skid plates to protect its various mechanical bits, while the suspension will feature Multimatic DSSV dampers used in the Silverado ZR2.
Under the hood, the 2022 GMC Sierra AT4X will come equipped as standard with the naturally aspirated 6.2L V8 L87, rated at 420 horsepower and 460 pound-feet of torque, mated to GM’s ten-speed automatic transmission.
The drivetrain will feature a set of front and rear e-lockers, which will work to enhance traction on a variety of surfaces, including while rock crawling. The new Terrain Mode, introduced on the ZR2, will allow drivers to use one-pedal driving while negotiating technical terrain.
The entire ensemble will ride on a set of 18-inch wheels wrapped in 33-inch Goodyear Wrangler Territory tires.
Like the refreshed 2022 Chevy Silverado 1500, the 2022 model year will also introduce a full model refresh for the GMC Sierra, following on the heels of the pre-refreshed 2022 GMC Sierra 1500 Limited.
That means that the 2022 GMC Sierra AT4X will benefit from the same updates as the rest of the refreshed 2022 GMC Sierra 1500 lineup, including a completely overhauled interior, plus added safety and convenience technologies. The GM Super Cruise semi-autonomous driving system will be reserved for the range-topping Denali trim, which should also get a completely unique interior from the rest of the 2022 Sierra 1500 range.
