The upcoming 2023 GMC Sierra AT4X is the company’s new off-road variant, and it looks better than the standard Sierra. As far as we are aware, this model will share the same mechanical components as the Chevy Silverado ZR2. It is powered by a familiar V8 engine and an automatic transmission with ten speeds. However, it has some material that is not available on the ZR2.
Moreover, the AT4X’s interior is incredibly luxurious and in line with premium Denali trim level. The interior wears nice leather upholstery and it also offers larger display and new safety aids. The sales will begin later next year.

GMC Sierra AT4X Adds a Lot of Stuff
The new 2023 GMC Sierra AT4X is more appealing than the standard model, owing to numerous enhancements. This version represents the peak of GMC’s lineup, sitting above the previous GMC Sierra AT4. It comes equipped with a huge grille, beautiful headlights, and black 18-inch wheels.
Moreover, the new AT4X is available with a variety of rocker guard attachments and Multimatic’s DSSV spool-valve dampers. We saw similar dampers on the Colorado ZR2 and Silverado ZR2. Furthermore, these dampers come with individual springs, which together enhance the maximum front suspension travel. Generally, AT4X is even more off-road-oriented variant than the current Sierra AT4.

Interior Upgrades
The cabin of the 2023 GMC Sierra AT4X is both modern and roomy. The new trim level will include the same distinctive “Obsidian Rush” inside treatment as the Denali trim. Comfort is unmatched, with superior leather upholstery accented by white trims and red contrast stitching. By and large, the forthcoming AT4X boasts even more features than the Denali.
The nice leather is offset by Vanta ash wood trim, and the maker included 16-way power-adjustable and massaging front seats. Moreover, a 15-inch display and a stunning 12-speaker Bose sound system are included as standard equipment.

Powerful V8 Gasoline Engine
The new 2023 GMC Sierra AT4X is an off-road pickup truck that sits on the same chassis as the Chevy Silverado ZR2. It comes standard with a 6.2-liter V8 gasoline engine delivering 420 horsepower and 460 lb-ft of torque. This engine transmits power to the rear wheels via a seamless 10-speed automatic transmission and a two-speed transfer case.
On top of that, GMC boasts that it has numerous driving modes, including Terrain Mode for rock crawling. Unlike the standard form, the AT4X additionally features electronic locking differentials in the front and back, a unique chassis, and modified suspension. Payload capacity is 1,430 pounds, while trailering capacity is almost 9,000 pounds.
