GMC Reveals Its Most Brutal Off-Road Sierra Ever

After the success of its AT4 trim level, GMC followed up with a even more luxurious off-road trim level called AT4X. O GMC Sierra 1500 AT4X 2023 based on the AT4 formula with Multimatic Dynamic Suspension, more suspension travel and additional underbody protection. We didn't think GMC would go further with the Sierra's off-road capability, but the American automaker has once again upped the ante with a new AEV (American Expedition Vehicles) edition.

GMC unveiled the AT4X AEV Edition at the Overland Expo Pacific Northwest and boldly proclaimed this to be the "most off-road capable Sierra 1500 factory ever". The AEV Edition adds stamped steel bumpers with heavy-duty recovery points, winch capability, five hot stamped boron steel skid plates, laser-etched 18-inch AEV Salta wheels with a built-in air valve system , 33-inch Goodyear Wrangler Territory MT tires, and off-road rocker panel protectors available.

Visually, GMC has changed the grille and front fascia to accommodate the new bumper and larger tires. Not only does it look suitably aggressive, it also improves off-road stats. GMC says the forward approach angle improves the most to 32.5 degrees (up from 25.4 degrees). The departure angle improves to 23.4 degrees (up from 23 degrees), while the breakout angle improves to 23.0 degrees (up from 22.7 degrees). The truck's ground clearance also increases to 11.2 inches (up from 10.8 inches).

“The Sierra 1500 AT4X is an incredibly formidable platform when it comes to on- and off-road performance and capability,” said AEV CEO and Founder Dave Harriton. “We've taken our signature approach to help take this truck's inherent off-road capability to the next level. We are confident that customers will love the result.”

This is not the first time AEV has helped a GM, having previously worked on the Chevrolet Colorado ZR2 Bison. Although we must admit that “Bison” is a much cooler name than “AEV Edition”.

Inside, the AEV Edition is extremely stylish, with details like massage front seats in full-grain leather, Vanta ash wood trim, 12-speaker Bose audio system, and over 40 inches of screen in total. To set it apart a bit from the standard AT4X, the AEV Edition gets special branding, including embroidered headrests and all-weather mats. Under the hood, the 6.2-liter V8 engine remains unchanged, still producing 420 horsepower and 460 lb-ft of torque through a 10-speed automatic transmission.

GMC says the AT4X AEV Edition can tow 8,700 pounds with a payload capacity of 1,290 pounds. Pricing has not been announced, but we imagine it will be more than the standard AT4X, which starts at around US$ 75,000.
