Key Features of the 2026 GMC Sierra 1500

TurboMax™ Engine

The TurboMax™ engine is a standout for everyday power and confident towing. It delivers 310 horsepower and a best-in-class standard torque figure of 430 lb.-ft. That torque comes on early, so merging, passing, and pulling a trailer feels natural rather than forced. With the TurboMax™ engine, Sierra offers available max towing of up to 9,400 lbs., giving you the flexibility to haul a boat, cargo trailer, or small camper. It’s engineered for durability and backed by a 5 years/100,000 miles Powertrain Limited Warranty, adding long-term peace of mind. For many shoppers whose daily drive mixes highway miles with occasional heavy lifting, this engine strikes a compelling balance of grunt, refinement, and value.

Duramax® 3.0L Turbo-Diesel

When long-distance towing and torque-rich drivability are top priorities, the available Duramax® 3.0L Turbo-Diesel delivers. Paired with a 10-speed automatic transmission, it’s refined at cruising speed and muscular when loaded, with an available max diesel towing capacity of up to 13,300 lbs. Beyond the numbers, the diesel’s smooth, low-end pull makes steady-state towing more relaxed, and the broad gear spread of the 10-speed helps keep the engine in its sweet spot. Match it with the available Max Trailering Package on SLE, Elevation, or SLT for hardware that supports sustained hauling. If your calendar includes frequent trips with a trailer in tow, the Duramax® powertrain is purpose-built for the job.

ProGrade® Trailering System

Trailering becomes more intuitive with the available ProGrade® Trailering System. Integrated tools help streamline hitching and towing, including the In-Vehicle Trailering App that supports custom trailer profiles, trailer statuses, and checklists right on the 13.4-inch infotainment screen. An integrated Trailer Brake Controller pairs with the antilock brake system to help provide measured brake force signaling to electric-controlled trailer systems. Add the available 9.76-inch rear axle, enhanced cooling radiator, revised shock tuning, heavier-duty rear springs, and 220-amp alternator from the Max Trailering Package, and the Sierra is engineered for stability and control. It’s a comprehensive, driver-friendly approach that helps you tow with confidence from your first hookup to your last mile home.

GMC MultiPro™ Tailgate

The world’s first available six-function MultiPro™ Tailgate transforms the Sierra’s cargo box into a versatile workstation. It offers step-assist, load-stop positions, and a fold-down inner gate that doubles as a standing desk or long-load support. For tailgating or campsite downtime, pair it with the available MultiPro Tailgate Audio System by KICKER for outdoors-ready entertainment right from the tailgate. The available CarbonPro® composite bed further elevates utility with best-in-class short bed cargo volume and a durable, dent- and corrosion-resistant surface. Together, MultiPro™ and CarbonPro® turn capability into convenience, letting you organize, secure, and access gear with far less hassle.

AT4X Off-Road Capability

For serious trail work, Sierra AT4X is equipped to take on challenging terrain. It adds front and rear electronic locking differentials — a combination not offered by any competitor in its class — to enhance traction across uneven surfaces. Multimatic® DSSV dampers deliver precise damping control over rocks and washboard, while robust underbody protection helps guard critical components. Shoppers can also opt for the AT4X AEV® Edition, outfitted with AEV stamped steel front and rear bumpers with front winch capability, multiple hot-stamped boron steel skid plates, and distinctive AEV badging. Even the AT4 brings a 2-inch factory lift, off-road suspension with Rancho® monotube shocks, a two-speed Autotrac® transfer case, and underbody skid plates. If your weekends take you off the beaten path, the AT4 and AT4X are more than just looks — they’re engineered for adventure.
