      Notes from the dealer

      2025 GMC SIERRA 1500 DENALI 4WD 6.2L V8 RESERVE PACKAGE TECHNOLOGY PACKAGE SUNROOF ACTIVE EXHAUST THUNDERSTORM GRAY LANCASTER PA

      This 2025 GMC Sierra 1500 Denali 4WD is powered by the 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission. Finished in stunning Thunderstorm Gray with a Jet Black leather interior, this loaded Denali features the Denali Reserve Package, Technology Package, power sunroof, active exhaust, 22-inch wheels, and GMC MultiPro power running boards.

      The 6.2L V8 delivers 420 horsepower and 460 lb-ft of torque, giving this Sierra impressive acceleration, strong towing performance, and the unmistakable sound of a traditional V8. The active exhaust adds an aggressive exhaust note that makes this truck even more enjoyable to drive.

      The Denali Reserve Package takes this truck well beyond a standard Sierra. Its 22-inch painted aluminum wheels, power running boards, signature chrome Denali grille, and premium exterior details give it an upscale appearance. Thunderstorm Gray is an especially sharp color that perfectly complements the Denali's bold styling.

      Inside, you'll find perforated leather seating, heated and ventilated front seats, heated rear outboard seats, Bose premium audio, and a power sunroof. Additional conveniences include wireless charging, remote start, a power-sliding rear window, and a power-adjustable steering column.

      The Technology Package is another major highlight, featuring a massive 15-inch Head-Up Display, Rear Camera Mirror, HD Surround Vision, and Bed View Camera. These features make everyday driving, parking, and maneuvering this full-size truck easier.

      Safety technology includes Rear Cross Traffic Braking, Rear Pedestrian Detection, Trailer Side Blind Zone Alert, and front and rear parking sensors.

      This Sierra is also ready to tow with an integrated trailer brake controller, Hitch Guidance with Hitch View, trailer camera provisions, and GMC's in-vehicle trailering app. An automatic locking rear differential and Hill Descent Control add confidence when driving in challenging conditions.

      Additional equipment includes navigation, rain-sensing wipers, LED bed lighting, a factory spray-on bedliner, rear wheelhouse liners, and 120-volt power outlets in the cab and bed.

      Finding a Denali with the 6.2L V8, active exhaust, Reserve Package, Technology Package, sunroof, and 22-inch wheels makes this an especially desirable configuration. Even better, the odometer is an impressive 15,770 miles below the market average!
