The fully refreshed 2022 GMC Sierra 1500 once again offers the AT4 off-roading trim level, as well as a long list of updates and changes over the preceding 2021 model year and pre-refresh 2022 GMC Sierra 1500 Limited. Now, GM Authority is taking a closer look at the refreshed 2022 GMC Sierra AT4.
To note, the latest model refresh introduces two new trim levels to the lineup, including a new range-topper, the Sierra Denali Ultimate, and a new, more-capable off-roader, the AT4X. The 2022 GMC Sierra AT4 slots in below the AT4X, once again offering the same off-roading capability as Sierra AT4 models of the past past, but not the same level of capability as the new AT4X.
Up front, the 2022 GMC Sierra AT4 is equipped with a revised fascia treatment, similar to the rest of the refreshed 2022 GMC Sierra 1500 lineup. Unique features include an AT4 badge located in the lower driver’s-side corner of the grille, while the horizontal slats covering the primary air intake get a dark finish. The GMC badge is done in red, as are the tow hooks located lower in the fascia. The front air dam was removed for greater clearance. The headlights were also revised for the 2022-model-year refresh with new lighting signatures and housings.
Compared to the AT4X, the standard AT4 has a darker grille finish and a different grille badge.
In the sides, we find the 2022 GMC Sierra AT4 equipped with 18-inch wheels with a high-gloss black finish, wrapped in Goodyear Wrangler DuraTrac® mud-terrain tires. The stance is once again taller thanks to a 2-inch factory suspension lift and Rancho monotube shocks, as compared to the Multimatic DSSV dampers equipped by the AT4X. In back, the Sierra AT4 offers the CarbonPro carbon-fiber composite bed as an optional extra.
As for the greasy bits, the 2022 GMC Sierra AT4 features the 3.0L I6 LM2 turbodiesel Duramax engine as standard, while the naturally aspirated 6.2L V8 L87 gasoline engine is optional. Both pair to a 10-speed automatic transmission, while a two-speed AutoTrac transfer case and automatic locking rear differential help to put the muscle down. Underbody skid plates provide protection.
Pricing for the refreshed 2022 GMC Sierra AT4 starts at $60,995. The first units of the refreshed 2022 GMC Sierra 1500 will hit dealers in Q1 of the 2022 calendar year, while production will initially take place at the GM Silao plant in Mexico and the GM Fort Wayne plant in Indiana, followed by the GM Oshawa plant in Canada following the completion of renovations.
