Description for 2026 GMC Sierra 1500 AT4 Crew Cab

The 2026 GMC Sierra 1500 AT4 is designed to balance premium comfort with the capability needed for off-road adventures and demanding work. Powered by a 3.0-liter inline-six engine paired with a 10-speed automatic transmission, it delivers the strength to tow, haul, and climb with confidence. The four-wheel-drive system, auto-locking rear differential, and hill descent control provide stability and traction when terrain gets challenging, while red recovery hooks and the AT4s off-road suspension tuning reinforce its purpose-built design. A heavy-duty air filter supports performance in dusty conditions, making it well suited for trails and worksites.Exterior features such as a black chrome grille, red tow hooks, perimeter lighting, and high-clearance steps emphasize utility while still maintaining a distinct style. The spray-on bedliner with GMC logo, 120-volt bed-mounted outlet, and LED cargo area lighting add practical function for hauling and working at any time of day. A bed view camera, hitch guidance, hitch view, and the in-vehicle trailering app combine with trailer camera provisions and an integrated brake controller to give the driver clear confidence while towing.Inside, the AT4 provides a refined but durable cabin with Jet Black leather accented by Kalahari trim. Heated and ventilated front seats, along with heated second-row outboard seats, ensure year-round comfort. The floor-mounted center console and rear seat storage options support everyday practicality. Technology is at the forefront with a multicolor 15-inch head-up display, navigation system, rear camera mirror, and HD Surround Vision to increase awareness on the road and trail. Safety systems such as rear cross traffic braking, trailer side blind zone alert, rear pedestrian detection, and ultrasonic front and rear park assist extend driver confidence in busy areas or tight spaces.The cabin integrates connectivity and entertainment features to match modern expectations. A premium Bose seven-speaker audio system, wireless Apple CarPlay and Android Auto, wireless charging, and a Wi-Fi hotspot keep passengers connected and entertained on longer drives. Keyless open and start, a remote start system, and a universal home remote add convenience to everyday use.The Sierra 1500 AT4 comes equipped with the AT4 Preferred and Premium Packages, enhancing both comfort and functionality. Rain-sensing wipers, power sliding rear window, power rake and telescoping steering column, and rear wheelhouse liners further elevate its blend of luxury and practicality.For buyers seeking peace of mind, this truck is also backed by the Walt Massey 3 Day Money Back Guarantee. This program allows an exchange if the vehicle is returned in like-new condition to the dealership within three business days of purchase before 5 p.m. CST. The vehicle must have fewer than 300 miles added, though returns are still accepted beyond that threshold with a charge of one dollar per additional mile. This ensures flexibility and confidence in choosing the right vehicle. Price includes: $1750 - Buick & GMC Consumer Cash Program. Exp. 09/30/2025
