Key Features of the 2026 GMC Sierra 1500

TurboMax™ engine

At the heart of Sierra’s standard power is the TurboMax™ engine, tuned to produce 310 horsepower and a best-in-class standard 430 lb.-ft. of torque. That torque curve is not just a statistic—it translates to confident launches with a loaded bed, relaxed passing at highway speeds, and smooth, predictable towing manners. The TurboMax™ engine is engineered with durability in mind and is paired with a comprehensive Powertrain Limited Warranty. When properly equipped, this powerplant enables available towing up to 9,400 lbs., and its broad midrange response helps you move heavy cargo without drama. For many owners, TurboMax™ delivers the ideal balance of everyday drivability and serious work capability, while also keeping weight down over the front axle for stable handling. It is the perfect foundation for a truck that needs to do everything well.

ProGrade® Trailering System

GMC’s available ProGrade® Trailering System brings clarity and control to the entire towing process. Using the in-vehicle Trailering App, you can create custom trailer profiles, run pre-departure checklists, and monitor critical statuses while you drive. Hitch Guidance overlays help align ball and coupler precisely, reducing frustration when connecting. Pair this with the available integrated trailer brake controller for measured, confident stops that communicate seamlessly with electric-controlled trailer braking systems. For heavier builds, the available Max Trailering Package on select trims adds a 9.76" rear axle, enhanced cooling, revised shock tuning, heavier-duty rear springs, and a high-output alternator to stabilize loads and keep power delivery consistent on long grades. It all comes together to make towing feel natural, whether you are pulling a boat, camper, or work trailer.

Super Cruise® hands-free driver assistance technology

Available on select trims, Super Cruise® hands-free driver assistance technology is engineered to bring a new level of confidence to highway travel on compatible roads. When conditions permit, it can maintain lane position and following gap, and it supports features like automatic lane changes on compatible routes. Super Cruise® relies on a sophisticated driver attention system and a network of precise map data to enable hands-free comfort for long stretches, helping reduce fatigue on commutes and cross-state trips alike. The steering wheel light bar communicates system status intuitively, while on-screen prompts keep the experience transparent and predictable. It is the kind of high-end capability that makes Sierra feel as advanced as it is powerful.

MultiPro™ Tailgate

The world’s first six-function GMC MultiPro™ Tailgate turns the Sierra’s bed into a flexible jobsite and weekend hub. Its design incorporates load stops for securing long items, a full-width step for easy bed access, and a primary gate that can morph into a work surface for on-the-go tasks. Pair it with the available MultiPro Tailgate Audio System by KICKER for an outdoor soundtrack at the campsite or your driveway project. Sierra’s high-strength steel bed also features multiple tie-downs and an available spray-on bedliner to protect against wear. The result is real adaptability—carry plywood one day, step up to access gear the next, and set up a portable workstation whenever you need it.

Denali Ultimate interior

Stepping into the Denali Ultimate places you in one of the most sophisticated cabins available in a full-size pickup. 16-way power front seats with massage, Forge perforated-leather seating surfaces, and authentic open-pore wood and patterned aluminum trim set an unmistakably premium tone. Audio is elevated by an available 12-Speaker Bose Premium Series with Centerpoint surround sound, and the digital experience comes alive through a 12.3" diagonal Driver Information Center and a 13.4" diagonal Premium GMC Infotainment System with Google built-in compatibility. The attention to detail extends to the smallest surfaces, while innovative driver assistance features—such as available Super Cruise®—reinforce that comfort and confidence can coexist with serious capability.
