See what comes with the 2026 GMC Sierra 1500 Elevation Premium Package, including leather seats, Bose audio, Adaptive Cruise Control and more. The 2026 GMC Sierra 1500 Elevation Premium Package adds several comfort, technology, safety and appearance features to the Elevation, including leather-appointed front bucket seats, Bose audio, Adaptive Cruise Control, Hitch View and wireless smartphone charging. It is useful to understand this package because two Sierra 1500 Elevation trucks can have noticeably different interiors and equipment. What Is Standard on the 2026 Sierra 1500 Elevation? The Elevation already includes several upgrades over the lower Sierra trims. GMC lists features including a 13.4-inch Premium GMC Infotainment System with Google built-in compatibility, along with heated front seating and a heated steering wheel as part of the Elevation's equipment. The Elevation also has distinctive exterior details such as a body-color grille header with gloss-black mesh inserts. The standard engine is the TurboMax, which produces 310 horsepower and 430 lb.-ft. of torque and is paired with an 8-speed automatic transmission. Other powertrain choices are available depending on configuration. What Does the Elevation Premium Package Add? GMC lists the following among the key features of the Elevation Premium Package: Comfort & Interior Jet Black leather-appointed front bucket seats Center console Up-level rear-seat storage Wireless smartphone charging Technology & Equipment 7-speaker Bose Premium Audio System with Richbass woofer Adaptive Cruise Control Hitch View Spray-on bedliner with GMC logo 6-inch black rectangular assist steps These features change both the cabin and the everyday equipment compared with a more basic Elevation configuration. Does Every 2026 Sierra 1500 Elevation Have Leather Seats? No. Leather-appointed front seats are not standard equipment on every Elevation. GMC's current build information shows cloth seating with a 40/20/40 split-bench front seat as standard on an Elevation configuration, while the Elevation Premium Package adds Jet Black leather-appointed front bucket seats and a center console. That makes the package especially important to check when comparing Elevation trucks online. What This Means When Shopping for an Elevation Do not assume that every Sierra 1500 Elevation has the same interior simply because the exterior trim name is the same. One Elevation may have the standard bench-seat layout, while an Elevation equipped with the Premium Package can have leather-appointed bucket seats, a center console, wireless charging and additional driver-assistance equipment. When browsing inventory at Dave Sinclair Buick GMC in St. Louis, check each Sierra Elevation's individual equipment or contact the dealership if you are trying to find a particular configuration.

The 2026 GMC Sierra 1500 AT4X AEV Edition is an available version of the AT4X that adds specialized off-road equipment and AEV-specific design details developed with American Expedition Vehicles. It does not replace the AT4X. Instead, it builds on the equipment already included with the AT4X. What Does the Regular Sierra 1500 AT4X Already Have? Before looking at the AEV Edition, it helps to understand the regular AT4X. The 2026 Sierra 1500 AT4X already includes equipment such as: Front and rear electronic-locking differentials Multimatic DSSV dampers 2-inch factory suspension lift AEV stamped-steel front bumper Front winch capability Stamped boron-steel front approach skid plate 16-way heated and ventilated front seats with massage Those features are part of the AT4X itself, not features that require the AEV Edition. What Does the AT4X AEV Edition Add? The AEV Edition builds on that foundation with additional AEV equipment. Protection & Off-Road Equipment AEV stamped-steel front and rear bumpers Front winch capability Five hot-stamped boron-steel AEV skid plates Off-road rocker-panel protectors Wheels & AEV Details AEV racing-inspired Salta wheels with a 12-spoke design AEV exterior badging AEV-branded interior details An optional bolt-on step assist is also offered for use when the truck is not being driven off-road. How Is the AEV Edition Different From a Regular AT4X? The biggest difference is that the regular AT4X already supplies the core off-road equipment, including its electronic-locking differentials and Multimatic DSSV dampers. The AEV Edition adds another layer of specialized protection, bumpers, wheels and AEV-specific details. That distinction is useful when shopping because seeing "AT4X" does not automatically mean the truck has the complete AEV Edition. Is the AT4X AEV Edition a Separate Sierra Trim? GMC presents the AT4X as the trim and the AEV Edition as an available edition of the AT4X. For shoppers, the important question is therefore not simply whether a Sierra is an AT4X. It is whether that specific AT4X is equipped with the AEV Edition. Dave Sinclair Buick GMC in St. Louis can help you identify whether a Sierra 1500 AT4X has the AEV Edition and compare its equipment with a standard AT4X.
