Key Features of the 2026 GMC Sierra 1500

TurboMax™ Engine With Best-in-Class Standard Torque

The TurboMax™ engine is the heart of Sierra 1500’s standard capability, delivering 310 horsepower and best-in-class standard torque of 430 lb.-ft. That abundant low-end twist is exactly what you want for launching a trailer from a stop, merging with authority on a short on-ramp, or climbing coastal grades without constant gear hunting. It’s paired with a robust automatic transmission and backed by a 5 years/100,000 miles Powertrain Limited Warranty, emphasizing long-term confidence. For drivers who prefer the character of naturally aspirated power, available 5.3L and 6.2L V8 engines broaden your options. And if maximum highway range and confident towing are priorities, the available Duramax® 3.0L Turbo-Diesel delivers refined torque and excellent composure while working hard.

Available Duramax® 3.0L Turbo-Diesel and Max Diesel Towing up to 13,300 lbs

When you equip Sierra 1500 for serious hauling, the available Duramax® 3.0L Turbo-Diesel pairs strong torque with highway composure and an available max diesel towing capacity of up to 13,300 lbs. It’s a combination built for long days with a boat, work trailer, or camper in tow. The available Max Trailering Package adds hardware such as a 9.76" rear axle, enhanced cooling radiator, revised shock tuning, heavier-duty rear springs, and a 220-amp alternator to help stabilize loads. An available integrated trailer brake controller works with the antilock braking system (ABS) to deliver measured brake force signaling to compatible trailer systems. Add the In-Vehicle Trailering App and you can create custom trailer profiles, monitor statuses, and keep key information at your fingertips while you drive.

Super Cruise® Hands-Free Driver Assistance Technology

Available Super Cruise® takes long-haul comfort to another level by enabling hands-free driving on compatible roads. Sierra 1500 models equipped with Super Cruise® use precision mapping, camera and sensor technology, and attentive monitoring to help maintain lane position and manage following distance, even when you’re trailering. Denali Ultimate includes Super Cruise® with a 3-year OnStar® One plan, integrating this cutting-edge system directly into the premium ownership experience. Super Cruise® does not replace driver attention, but it meaningfully reduces fatigue on familiar regional routes and extended road trips.

World’s First Six-Function MultiPro™ Tailgate

The MultiPro™ Tailgate is a GMC hallmark because it solves real problems daily. Six integrated functions help you load, organize, and access cargo. Use the primary gate as usual, deploy the inner gate as a load stop for longer items, or convert it into a handy work surface. A full-width step helps you climb into the bed more easily, and you can even add the available MultiPro Tailgate Audio System by KICKER® to bring entertainment to the campsite or jobsite. Pair the tailgate’s versatility with the available spray-on bedliner and 12 standard cargo tie-downs, and Sierra 1500’s bed is ready for work, play, and everything between.

13.4" Premium GMC Infotainment System and 12.3" Driver Information Center

Sierra 1500’s cabin is a tech-forward command center. The available 13.4" diagonal Premium GMC Infotainment System with Google built-in compatibility integrates navigation, media, and voice assistance on a vibrant touchscreen. The 12.3" diagonal Driver Information Center presents your choice of Classic, Progressive, Digital, or Clean layouts, so you always see key details at a glance. Available features like a 15" diagonal multicolor Head-Up Display in certain trims, a heated steering wheel, heated and ventilated front seats, and an available Bose® Premium Series with Centerpoint® surround sound complete the experience. Denali and Denali Ultimate elevate materials with authentic wood and Forge perforated-leather seating surfaces, while AT4X brings premium appointments with an adventurous aesthetic.
