Key Features of the 2026 GMC Sierra 1500

TurboMax™ engine

The standard TurboMax™ engine sets a high baseline, delivering 310 horsepower and best-in-class standard torque of 430 lb.-ft. That torque arrives early, helping you launch with confidence when merging, passing, or pulling a trailer. GMC’s engineering focus extends to longevity and peace of mind, backed by a 5 years/100,000 miles Powertrain Limited Warranty. When properly equipped, the TurboMax™ can offer available max towing of up to 9,400 lbs., making it an excellent everyday solution for light-to-moderate trailering without sacrificing efficiency or smoothness. Paired with an 8-speed or 10-speed automatic transmission depending on configuration, shifts are calibrated for a responsive, refined feel. If you need compelling torque and a composed ride in your full-size truck, this powertrain delivers.

Duramax® 3.0L Turbo-Diesel

For drivers who want diesel pulling power with quiet composure, the available Duramax® 3.0L Turbo-Diesel is a standout match. It is engineered for sustained torque under load and optimized for long highway grades and varied weather. When properly equipped, the 2026 Sierra 1500 with the Duramax® can reach an available max diesel towing capacity of up to 13,300 lbs., aligning capability with confidence. This engine integrates seamlessly with GMC’s trailering technologies, allowing you to take advantage of features like the available ProGrade® Trailering System and the In-Vehicle Trailering App to monitor trailer statuses. Pair it with the available 10-speed automatic for smooth, predictable shifts and a relaxed cruising character that makes long trips feel shorter.

Super Cruise® hands-free driver assistance technology

Available on select trims — and standard on Denali Ultimate — Super Cruise® hands-free driver assistance technology brings a new level of long-haul confidence. On compatible roads, it can enable hands-free driving and help reduce fatigue by assisting with steering and speed control. The system integrates with key vehicle systems and uses driver attention monitoring to support safe use. Paired with available Adaptive Cruise Control, the truck can maintain a driver-selected following gap to a detected vehicle ahead, further easing congested stretches. GMC’s thoughtful integration keeps controls intuitive via steering-wheel buttons and clear visual cues, so using Super Cruise® quickly becomes second nature on your regular routes.

ProGrade® Trailering System

Available trailering tools are designed to simplify your entire towing routine. The ProGrade® Trailering System brings integrated checklists, hitch guidance, and customizable trailer profiles that save valuable time when you are setting up or swapping between trailers. The available In-Vehicle Trailering App can display trailer statuses, tire checks, and light tests right on the 13.4" display. Add the available integrated Trailer Brake Controller — linked with the antilock braking system for measured brake force signaling — and the available Max Trailering Package, and you have a cohesive suite that builds confidence from hookup to highway. It is a smarter, more streamlined approach to towing that supports novices and seasoned haulers alike.

MultiPro™ Tailgate

GMC’s world’s first six-function MultiPro™ Tailgate is available across the lineup and proves its value daily. Configure it to ease loading, create a work surface, add a second-tier load stop, or use the inner gate to access cargo closer to the cab. Pair it with the available MultiPro Tailgate Audio System by KICKER for camp-ready entertainment that draws power from the truck without extra wires. Beyond the tailgate, the Sierra’s high-strength steel bed is available with a spray-on bedliner and can be optioned with the CarbonPro® composite bed on select trims for rugged durability and best-in-class short bed cargo volume. This is practical innovation that expands what your truck can do on and off the clock.
