2023 GMC Sierra AT4X: What You Need to Know

The all-new 2023 GMC Sierra AT4X, which will be available sometime next year, is the company’s latest off-road model, and it appears hotter than the conventional Sierra. As far as we know, this model will be mechanically identical to the Chevy Silverado ZR2. A familiar V8 engine and a ten-speed transmission will be on offer. However, it includes some content that is not included on the ZR2.

Furthermore, the AT4X’s interior is quite premium, matching the famous Denali trim level. The interior features plush leather upholstery, a bigger display, and improved safety features. The sales will commence in the second half of next year.

Due to several upgrades, the approaching 2023 GMC Sierra AT4X is more attractive than the standard model. This version is the pinnacle of GMC’s portfolio, ranking higher than the previous GMC Sierra AT4. It features a massive grille, stunning headlamps, and black 18-inch rims.

Additionally, this version will include rock guards and brand-new Multimatic dampers. On the Colorado ZR2 and Silverado ZR2, we noticed identical dampers. Moreover, these dampers include independent springs, which collectively increase the front suspension’s maximum travel. By and large, AT4X is a more off-road-oriented variation than the Sierra AT4 trim level.

From what we know, the AT4X will provide the same premium stuff as the Denali trim level.

The luxurious leather is combined with beautiful Vanta ash wood trim, and the manufacturer provides 16-way power-adjustable and massaging front seats. Furthermore, a 15-inch touchscreen and a magnificent Bose sound system are available as standard.
