Key Features of the 2026 GMC Sierra 1500

TurboMax™ Engine

The heart of every Sierra 1500 is capability, and the TurboMax™ engine proves it. With 310 horsepower and best-in-class standard torque of 430 lb-ft, TurboMax pairs strong low-end muscle with smooth, responsive power delivery for everyday confidence. That torque helps you get moving with a trailer, pull through steep grades, or navigate traffic with composure. When properly equipped, TurboMax offers available max towing of up to 9,400 lbs. It’s engineered for durability you can count on and backed by a 5-year/100,000 miles Powertrain Limited Warranty. If you want even more towing capacity for larger campers or enclosed trailers, the available Duramax® 3.0L Turbo-Diesel moves the bar higher, with available max diesel towing up to 13,300 lbs. Combine the engine of your choice with the right suspension and trailering packages, and you’ll have a Sierra 1500 tailored to the real demands of Colorado driving.

ProGrade® Trailering System

Towing is easier when your truck is designed to help. The available ProGrade® Trailering System brings integrated tools to your center screen to guide key steps and keep you informed. Use in-vehicle checklists to confirm tasks are complete, monitor trailer statuses, and access camera views to line up your hitch precisely. Pair it with the available Trailer Brake Controller, which integrates with the Sierra 1500’s antilock braking system to signal measured brake force to compatible trailers. Add the Max Trailering Package—available on select trims—for upgraded cooling, revised shock tuning, heavier-duty rear springs, and more. The result is a truck that not only tows confidently but also supports you with the right information at the right time. Whether you’re backing down a ramp with your boat or hauling a toy hauler into the foothills, Sierra 1500’s towing tech helps reduce guesswork and stress.

MultiPro™ Tailgate

The world’s first MultiPro™ Tailgate is more than a conversation starter—it is a daily advantage. Six configurable functions let you load, step in, stop cargo from sliding, and create a tiered load surface. A built-in inner gate with a load stop helps stabilize longer items, while the full-width step supports easy entry to the bed. Pair MultiPro with the available MultiPro Tailgate Audio System by KICKER for campsite tunes without opening the cab. For those who prioritize durability and capacity, opt for the available CarbonPro® composite bed. It offers excellent dent, scratch, and corrosion resistance and provides best-in-class short bed cargo volume, so you can load landscaping stone one day and mountain bikes the next without worry. Together, MultiPro and CarbonPro® transform the Sierra 1500’s bed into a smarter, tougher workspace.

Super Cruise® Hands-Free Driver Assistance Technology

On compatible roads, available Super Cruise® hands-free driver assistance technology can make long-distance travel feel easier and more relaxed. Using a network of sensors and GPS data, Super Cruise can maintain lane position and a driver-selected following gap on compatible mapped roads, allowing hands-free driving under proper conditions. Available on Denali and standard on Denali Ultimate with an included plan, Super Cruise pairs naturally with the Sierra 1500's available 13.4-inch Premium GMC Infotainment System with Google built-in compatibility and the available 12.3-inch Driver Information Center—so the essentials are always visible. Add the available 15-inch multicolor Head-Up Display to project key data onto the windshield. This integrated tech suite helps keep your focus on the road while surrounding you with helpful information, whether you’re crossing the plains or cruising mountain passes.

AT4X Off-Road Hardware with Multimatic® DSSV Dampers

Colorado trails ask more of a truck—and AT4X answers. Building on AT4’s factory lift, off-road suspension, and specialty hardware, AT4X adds Multimatic® DSSV dampers tuned for serious off-pavement control plus front and rear electronic locking differentials—a combination not offered by competitors in its class. With these tools, the Sierra 1500 can better manage wheel articulation, distribute torque across axles, and maintain traction on uneven, rocky terrain. For even more trail armor and functionality, the AT4X AEV® Edition equips stamped-steel bumpers with front winch capability, five hot-stamped boron steel skid plates, exclusive AEV badging, and rugged AEV Salta wheels. Hill Descent Control and selectable drive modes add confidence when the trail points down. If your weekends include shelf roads, trailheads, and light overlanding, AT4X is engineered to help you get there—and back—with control.
