The 2023 GMC Sierra introduces a number of important updates and changes over the preceding 2022 model year, including the introduction on the new GMC Sierra AT4X AEV Edition, a next-level off-roader boasting several components from American Expedition Vehicles (AEV). Now, we’re taking a closer look at the 2023 GMC Sierra AT4X AEV Edition with the first live photos.
GM unveiled the new 2023 GMC Sierra AT4X AEV Edition in July, framing it as the most off-road-capable factory GMC Sierra 1500 ever built. These latest photos, however, show the pickup as it stands in the real world. This particular example is a GM validation unit, and is covered in Onyx Black paint. To note, Onyx Black paint is available as an extra-charge color for an additional $495.
Standout equipment unique to the 2023 GMC Sierra AT4X AEV Edition include new bumper treatments, with an AEV stamped steel front and rear bumper added as standard. The front bumper also includes a provision for a winch, although we can’t make out whether or not this particular example is running a winch. Also notable items include heavy-duty recovery points in the bumpers.
Underneath the body, the 2023 GMC Sierra AT4X AEV Edition runs a set of five hot-stamped boron steel skid plates to protect the front approach, steering gear, transfer case, fuel tank, and rear differential. In the corners is a set of laser-engraved 18-inch AEV Salta wheels with a gloss black finish and recessed valve system, which are wrapped in chunky 33-inch Goodyear Wrangler Territory MT tires. The final production model will also offer off-road rocker protectors, which are not included with the validation model featured here.
In back, the unique rear bumper treatment is clearly visible, as is the AEV branding on the tailgate.
Under the hood, the 2023 GMC Sierra AT4X AEV Edition features the naturally aspirated 6.2L V8 L87 gasoline engine as standard. Output is rated at 420 horsepower and 460 pound-feet of torque, with the GM 10-speed automatic transmission on hand for the cog swaps.
Production of the 2023 GMC Sierra 1500 takes place at the GM Fort Wayne plant in Indiana, GM Oshawa plant in Canada, and GM Silao plant in Mexico. Under the skin, the light-duty pickup rides on the GM T1 platform.
