The 2026 GMC Sierra 1500 is powered by a TurboMax engine that produces 310 horsepower and best-in-class standard torque of 430 pound-feet, paired with an 8-speed automatic transmission. For those who demand more, an available 5.3-liter V8 engine with a 10-speed automatic transmission steps up the output, while the available 6.2-liter V8 engine delivers serious power for the biggest jobs.

Drivers who prioritize efficiency without sacrificing towing strength will appreciate the available Duramax 3.0-liter Turbo-Diesel engine, which enables a max diesel towing capacity of up to 13,300 pounds when properly equipped. Off-road enthusiasts will find plenty to love in the AT4 and AT4X trims, which feature a factory-installed 2-inch suspension lift, Rancho monotube shocks, underbody skid plates, and a two-speed Autotrac transfer case. The AT4X takes it further with Multimatic DSSV dampers and exclusive front and rear electronic locking differentials — a combination not offered on any competitor in its class.

Step inside the 2026 Sierra 1500 and you'll find a cabin crafted with genuine attention to detail and passenger comfort.

Trim-specific touches elevate the experience across the lineup: the Denali Ultimate features full-grain leather seating surfaces with plaited contrast stitching, the Denali showcases real wood trim and sophisticated accents, and the AT4X presents striking red double-needle stitching with ceramic white accents.

Available features include 10-way or 12-way power-adjustable front seats, heated and ventilated front outboard seats, a power lumbar, and a massage feature on select trims. Thoughtful storage solutions throughout the cabin keep work supplies and weekend gear organized without crowding passenger space.

The available GMC Infotainment System features Google built-in compatibility and voice-activated technology to keep you connected and entertained on the go.

Available Super Cruise hands-free driver assistance technology lets drivers go hands-free on a growing network of compatible roads, making long highway drives noticeably more relaxing. Up to 14 available camera views help you maneuver in tight spaces and hitch trailers with confidence, while the available ProGrade Trailering System streamlines the entire towing process from setup to arrival. The available 15-inch diagonal multicolor Head-Up Display keeps critical information squarely in your line of sight.

The Sierra 1500 also offers Terrain Mode on 4WD models equipped with a single-speed transfer case, providing finer control during low-speed, off-road driving scenarios.
