It will be a more hardcore version of the popular AT4 trim.
GM trademarked AT4-X some years ago.
All things off-road are trendy.
The automotive industry and buyers are hot for SUVs and anything that looks robust. A parallel trend involves offering off-road-ready iterations of these SUVs, trucks, station wagons, and even minivans. The 2022 GMC Sierra 1500 is about to get serious with an expected AT4-X trim.

GM’s displayed its off-roading know-how with the Chevrolet Colorado ZR2 and the demand for more specialized prepared vehicles. The AT4 trims have found favour with many truck buyers but one element was missing and that was more capability.
In the past, GMC offered the All Terrain X version of the previous generation Sierra 1500. The trim included mud-terrain tires, a bed-mounted sport bar, a performance exhaust system along with body colour and black accents. These elements were added on top of the All Terrain’s 4WD system with Eaton locking rear differential, Z71 off-road suspension, and more. When the current iteration launched for the 2019 model year, the new Sierra did without this trim, as specified by GM Authority.
In all likelihood, the AT4-X will feature larger mud-terrain tires and DSSV dampers from Multimatic, along with other off-roading goodies that will bridge the gap with the Colorado ZR2.
