Following the success of its AT4 trim level, GMC followed it up with an even more luxurious off-road trim level called the AT4X. The 2023 GMC Sierra 1500 AT4X builds on the AT4 formula with Multimatic Dynamic Suspension, more suspension travel, and additional underbody protection. We didn't think GMC would go even 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 revealed the AT4X AEV Edition at the Overland Expo Pacific Northwest, and boldly proclaimed this is the "most off-road capable factory Sierra 1500 ever." The AEV Edition adds stamped steel bumpers with heavy duty recovery points, winch capability, five hot-stamped boron steel skid plates, laser-engraved 18-inch AEV Salta wheels with a recessed air valve system, 33-inch Goodyear Wrangler Territory MT tires, and available off-road rocker panel protectors.

Visually, GMC changed out the grille and front fascia to accommodate the new bumper and larger tires. Not only does it look properly aggressive, but it also improves the off-road stats. GMC says the front approach angle sees the most improvement to 32.5 degrees (up from 25.4 degrees). The departure angle improves to 23.4 degrees (up from 23 degrees) while the breakover 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 took our signature approach to help elevate this truck's inherent off-road capability to the next level. We are confident customers will love the result."

This is not the first time AEV has lended a hand on a GM, having previously worked on the Chevrolet Colorado ZR2 Bison. Though we must admit "Bison" is a much cooler name than "AEV Edition."

Inside, the AEV Edition is extremely posh with niceties such as full grain leather massaging front seats, Vanta ash wood trim, a 12-speaker Bose audio system, and over 40 inches of screens total. To differentiate it a bit from the standard AT4X, the AEV Edition gets special branding, including embroidered head rests and all-weather floor mats. Under the hood, the 6.2-liter V8 engine is unchanged, still producing 420 horsepower and 460 lb-ft of torque going out through a 10-speed automatic transmission.

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