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.
