Key Features of the 2026 GMC Sierra 1500

TurboMax™ engine

For many buyers, the heart of the lineup is the TurboMax™ engine, rated at 310 horsepower and an impressive best-in-class standard 430 lb.-ft. of torque. That torque arrives early and stays steady, giving you strong launch with a trailer and confident midrange response for highway merges. With available max towing up to 9,400 lbs. when properly equipped, the TurboMax™ setup is a balanced choice for commuters who tow on weekends. Sierra also offers an available 5.3L V8 and an available 6.2L V8 for those who want a classic V8 feel, plus an available Duramax 3.0L Turbo-Diesel for smooth torque and long-range cruising. Across the range, smart transmission calibrations and selectable drive modes help you tailor shift logic to towing, off-road, or sport driving.

ProGrade® Trailering System

Available ProGrade® Trailering System technology takes the guesswork out of hitching and hauling. Integrated tools on the center display guide you with checklists, hitch guidance, and customizable trailer profiles. The available in-vehicle trailering app stores maintenance reminders, shows trailer status, and offers a pre-departure checklist for consistency every time you tow. Pair it with the available integrated trailer brake controller for measured braking and confidence on descents. Add multiple available camera views to see behind, beside, and around your trailer, and trailering becomes a process you can repeat smoothly—important when you change loads or alternate between a utility trailer and a camper.

Super Cruise® hands-free driver assistance technology

Available Super Cruise® brings compatible-road, hands-free convenience to Sierra 1500 Denali and Denali Ultimate, adding a new dimension to highway travel. Using a driver attention system, precision mapping, and adaptive controls, Super Cruise® can help steer, accelerate, and brake within its operational domain. For shoppers who run I-66 or the Dulles Greenway frequently, this feature helps reduce fatigue on long stretches of divided, compatible highways. More than a novelty, it is a confidence feature engineered to support your routine—backed by thoughtful integration with the Driver Information Center so you always know when the system is ready, active, or requires driver control.

MultiPro™ Tailgate

The world’s first available six-function MultiPro™ Tailgate is a force multiplier for job sites and weekend projects. Use it as a primary gate, a full-width load stop, a second-tier load stop, a step for easier bed access, or a work surface for laptops and tools. The optional MultiPro Tailgate Audio System by KICKER adds sound for tailgates and campsites without occupying bed space. When paired with the available high-strength steel bed or the available CarbonPro® composite bed, the tailgate’s versatility expands how you load materials, secure cargo, and organize gear—especially useful for contractors and DIYers who need flexible staging space built right into the truck.

AT4X off-road hardware with Multimatic® DSSV dampers

For drivers who traverse fire roads, rutted trails, or rocky creek beds, the AT4X configuration adds serious capability. It features Multimatic® DSSV dampers calibrated for precise wheel control, as well as front and rear electronic locking differentials—a combination not offered on any competitor in its class. Underbody skid plates, an off-road tuned suspension, and specialized bumpers with front recovery provisions reinforce its readiness for tough routes. Hill Descent Control supports controlled downhill pacing, while selectable traction modes help you dial in response. AT4 is also a compelling choice, offering a factory lift, two-speed transfer case, underbody protection, and rugged styling with Jet Black and Kalahari interior accents.
