This 2026 GMC Sierra 1500 AT4 commands attention in Summit White, backed by the muscle of GM's EcoTec3 6.2L V8 and 4WD capability built for real work and rugged terrain alike. EPA estimates land at 14 city and 17 highway MPG, and this Sierra comes with both a CARFAX One-Owner history and a Clean CARFAX report plus it's priced below KBB Fair Purchase Price, adding extra value on top of everything else this AT4 brings to the table.Inside, Jet Black upholstery with Kalahari accents and perforated front leather seat trim sets a rugged yet upscale tone. Heated and ventilated front seats and heated second-row outboard seats keep the whole cabin comfortable in any season, while a power rake-and-telescoping steering column helps you dial in the perfect driving position. Rounding out everyday livability are a floor-mounted center console, color-keyed carpeting, front and rear premium floor liners with removable carpet inserts, and power windows and locks throughout.Staying entertained and connected on the road is easy with the premium Bose 7-speaker sound system, a SiriusXM 360L trial subscription, and Wi-Fi hotspot capability, while wireless charging and a full complement of USB ports including dedicated bed-mounted and interior 120-volt power outlets keep devices and job-site equipment powered up. OnStar-capable connectivity, steering wheel audio controls, keyless open and start, push-button start, and a remote vehicle starter system round out a cabin built for convenience.On the safety side, HD Surround Vision and ultrasonic front and rear park assist make close-quarters maneuvering easier, while rear cross traffic braking and rear pedestrian detection add extra layers of protection around the vehicle. Front rain-sensing wipers, an electric rear-window defogger, and a theft deterrent system with perimeter lighting round out a suite built for confidence in any condition.True to its AT4 badge, this Sierra is built to work. The Trailering Package brings an integrated trailer brake controller, hitch guidance and hitch view camera angles, trailer camera provisions, and trailer side blind zone alert, all supported by the in-vehicle trailering system app for keeping tabs on your setup. An auto-locking rear differential, off-road suspension, and hill descent control add genuine off-pavement capability, while a heavy-duty air filter and 220-amp alternator help this Sierra handle demanding conditions. Red recovery hooks, a spray-on pickup bedliner with GMC logo, and rear wheelhouse liners round out a truck that's ready for both the trail and the job site.Outside, black chrome grille insert bars and deep-tinted glass give this Sierra a bold, purposeful look, while LED cargo area lighting adds practicality after dark. Wrapping things up, 20-inch x 9-inch machined aluminum wheels complete the Summit White exterior with a finished, confident stance.Ahead of delivery, this Sierra received a full service and pre-delivery inspection, including an emissions inspection, a fresh oil and filter change, and a complete wash and detail, so it's ready to go to work from day one.Find your next vehicle today at Bob Moore Cadillac of Norman.
