2023 GMC Sierra 1500 AT4X AEV Edition with custom styling, cool accessories, powerful engine and more

GMC recently debuted the 2023 Sierra 1500 AT4X AEV Edition at the Overland Expo Pacific Northwest event. The updated Sierra AT4X is a collaboration between General Motors and American Expedition Vehicles (AEV)—hence the AEV Edition branding—and is what GMC calls its most capable half-ton truck without downplaying its posh upbringing.

“GMC has been a pioneer in premium off-road space, and this Sierra 1500 AT4X AEV Edition raises the bar once again,” said Duncan Aldred, GMC Global Vice President. “Using GMC’s unwavering commitment to providing premium trucks and American Expedition Vehicles’ expertise in engineering and performance-driven parts and accessories, this truck delivers extreme capability, technology and comfort.”

The AT4X AEV Edition is, expectedly, home to a host of custom visual and performance-enhancing gear. Updates include AEV front and rear bumpers made from three millimeters of high-strength steel. The bumpers are powder coated and e-coated to repel UV rays and corrosion, while AEV claims it’s the only factory-installed front bumper that can winch out of the box. “We took our signature approach to help elevate this truck’s inherent off-road capability to the next level,” said Dave Harriton, AEV founder and CEO.

Meanwhile, the AEV Edition features a new front grille, larger 33-inch Goodyear Wrangler Territory mud tires, gloss black door handles and a black contrast on the inner tailgate. Also new are hot-stamped boron steel skid plates to protect the front, rear differential, steering gear, transmission and fuel tank from damage or punctures when venturing off the beaten path. Of course, the truck has a host of AEV badges inside and out to remind you of the truck’s on- and off-road prowess.

Better clearances

The Sierra 1500 AT4X AEV Edition is not just a cosmetic update. GMC claims better off-road stats than the outgoing Sierra 1500 AT4X. The AEV Edition has 11.2 inches of ground clearance, better than the previous 10.8 inches. In addition, the AEV Edition has a front approach angle of 32.5 degrees, a 23.4-degree departure angle and a breakover angle of 23 degrees, surpassing the outgoing AT4X in all aspects.

Standard V8 gas engine

The GMC Sierra 1500 is available with various engine options, but only the 6.2-liter V8 will do for the AT4X AEV Edition. It sends 420 horsepower and 460 lb-ft. of torque to all four wheels with a 10-speed automatic transmission. The drivetrain includes front and rear e-locking differentials and a two-speed transmission with selectable off-road modes. If it all sounds familiar, it’s the same hardware under the GMC Canyon AT4 OVRLANDX Concept that was unveiled in 2021.

In addition, the suspension consists of Multimatic DSSV dampers to provide better comfort on the road, superior off-road grip or both. “Our customers want an uncompromising combination of on-road technology and off-road capability,” Aldred added.

Towing & payload

The GMC Sierra 1500 AT4X AEV Edition has a maximum payload of 1,290 lbs. and can tow up to 8,700 lbs. Features such as the trailer camera system and a virtual rearview mirror camera make towing bulky items more manageable and safer.

Stylish interior

Calling it an “iron fist in a velvet glove” is such a cliché, but it defines the GMC Sierra AT4X AEV Edition to a T. GMC’s AT4X Obsidian Rush interior is standard and features full-grain leather upholstery, massaging front seats, genuine Vanta ash. trim and a Bose premium sound system with 12 speakers. Other goodies like a 13.4-inch infotainment touchscreen with Apple CarPlay, Android Auto and Bluetooth connectivity are standard fare.

Safety-wise, the AEV Edition comes standard with advanced driving aids like adaptive cruise control, trailer blind spot monitoring, automatic rear braking, a surround camera, front and rear parking sensors and more.

Pricing & Availability

The GMC Sierra AT4X AEV Edition won’t arrive in U.S. dealerships until early to mid-2023. Pricing and other related information are still to come, but you can expect a slight increase over a standard AT4X’s base price of $78,300.
