General Motors will introduce a new, more-robust off-roader variant of the 2022 GMC Sierra 1500 Limited dubbed the Sierra AT4-X, GM Authority has learned from sources familiar with the matter.
The new 2022 GMC Sierra AT4-X will slot in above the standard GMC Sierra AT4, with the former tagged as equipment group 4SB, and the latter tagged as equipment group 4SG.
It’s believed the new 2022 GMC Sierra AT4-X will offer more-robust off-roading features than the standard Sierra AT4, similar to the strategy employed with the Sierra 1500 All Terrain X edition offered for the 2017 and 2018 model years. For those readers who may not remember, the Sierra 1500 All Terrain X edition was introduced in 2016 as a special edition of the Sierra All Terrain, featuring exclusive premium content that enhanced the vehicle’s off-road capability, as well as adding an aggressive, monochromatic appearance.
The Sierra All Terrain X was discontinued with the introduction of the fourth-generation Sierra 1500 for the 2019 model year, at which time the All Terrain package was replaced by the AT4 trim level, which offered customers the same off-roading capabilities and bold exterior styling as the All Terrain sub-brand.
Now, General Motors is cooking up a fresh AT4-X model for the 2022 GMC Sierra 1500 Limited. As GM Authority covered previously, GM filed to trademark AT4X with the United States Patent and Trademark Office in 2016, while a more hardcore 2023 GMC Canyon prototype was spotted this month suggesting a new 2023 Canyon AT4-X model was in the works and that a Sierra AT4-X model was a distinct possibility.
As for the equipment specs, the 2022 GMC Sierra AT4-X could come equipped with larger tires and DSSV dampers, as well as new badging and other equipment that would give it similar outfit as the upcoming Chevy Silverado ZR2.
As a reminder, the 2022 GMC Sierra 1500 will introduce a complete refresh for the Light Duty pickup, including new styling, a completely overhauled interior, and new tech highlighted by features like the GM Super Cruise semi-autonomous driver assist system. However, prior to the launch of the fully refreshed 2022 GMC Sierra 1500, GMC will released the 2022 GMC Sierra 1500 Limited, a continuation model that will serve as a stop-gap to the fully refreshed model.
