The 2023 GMC Sierra 1500 introduces only a handful of changes and updates as compared to the full model refresh introduced for the 2022 GMC Sierra. One of those includes availability of a new Graphite Edition package on the base 2023 GMC Sierra Pro.
The biggest news is the debut of the first-ever 2023 GMC Sierra AT4X AEV Edition, which promises to push the capability of the new, go-anywhere AT4X trim level to new heights. Simply put, the 2023 Sierra 1500 AT4X AEV Edition is the most off-road capable factory Sierra 1500 ever, developed with input from American Expedition Vehicles (AEV), identical to the Chevy Colorado ZR2 Bison and first-ever 2023 Chevy Silverado 1500 ZR2 Bison.
Later on in the 2023 model year, the “standard” 2023 GMC Sierra AT4X will receive new equipment from the AEV Edition.
The fourth-generation GMC Sierra 1500 rides on the GM T1 platform shared with other GM full-size trucks and SUVs. Production of the 2023 GMC Sierra 1500 kicked off at the GM Fort Wayne plant in Indiana on August 20th, 2022, and at the GM Silao plant in Mexico on August 29th, 2022, for both Regular Cab and Crew Cab models, and on September 6th, 2022, for Double Cab models. The online configurator tool is now live for the 2023 Sierra 1500.
