2026 GMC Sierra 1500

At the heart of the 2026 GMC Sierra 1500 is the standard TurboMax engine, which produces 310 horsepower and a best-in-class standard torque of 430 pound-feet — all backed by a 5-year/100,000-mile Powertrain Limited Warranty. This engine pairs with an 8-speed automatic transmission and offers available max towing of up to 9,400 pounds when properly equipped.

For drivers who demand even more capability, the Sierra 1500 offers additional engine options to match virtually any need. The available 5.3-liter V8 engine with a 10-speed automatic transmission brings confident power to everyday tasks, while the available Duramax 3.0-liter Turbo-Diesel engine pushes max towing capacity to an impressive 13,300 pounds when properly equipped. Those seeking peak performance can opt for the available 6.2-liter V8 engine with a 10-speed automatic transmission.

Off-road performance reaches new heights with the AT4 and AT4X trims. The AT4 features a factory-installed 2-inch suspension lift, Rancho monotube shocks, a two-speed Autotrac transfer case, and underbody skid plates. The AT4X takes things 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 designed with equal attention to comfort and practicality. The truck offers best-in-class standard Crew Cab front head- and legroom, giving every passenger plenty of space to settle in for the long haul.

Interior appointments vary meaningfully across the trim lineup. The Denali Ultimate features full-grain leather seats with plaited contrast stitching, while the Denali brings authentic wood trim and sophisticated accents. The AT4X showcases red double-needle stitching and ceramic white accents, and the AT4 features heated and ventilated perforated front leather seating surfaces. Available seating configurations range from a 40/20/40 bench seat to available front bucket seats with wireless center console charging.

Smart, ample storage solutions are woven throughout the cabin, ensuring there's room for work supplies and weekend gear alike without compromising comfort. Available power-adjustable seating with lumbar support and heated and ventilated options make long drives feel effortless.

The 2026 GMC Sierra 1500 keeps drivers informed, connected, and in control. The available 13.4-inch diagonal multicolor touchscreen powers the Premium GMC Infotainment System with Google built-in compatibility and voice-activated technology. Combined with the 12.3-inch diagonal Driver Information Center, the Sierra 1500 offers over 40 inches of combined driver-focused digital displays — the most in its class.

Available Super Cruise hands-free driver assistance technology delivers a confident, relaxed drive on a growing network of compatible roads. It comes standard with a 3-year OnStar One plan on the Denali Ultimate and is available on the Denali trim.

Towing is made more manageable with the available ProGrade Trailering System, which integrates a suite of tools to streamline the hitching and towing process. Up to 14 available camera views help drivers navigate tight spaces and maneuver trailers with precision and confidence.

The 2026 Sierra 1500 comes equipped with GMC Pro Safety features designed to enhance driver awareness and help prevent collisions. This suite of collision-avoidance and driver assistance technologies gives every driver added confidence on the road.

Available features include Front and Rear Park Assist for navigating tight parking situations, and available HD Surround Vision that provides a bird's-eye view around the vehicle. Hill Descent Control is also available, using antilock braking technology to help deliver a smooth, controlled descent on steep grades.

It's worth noting that safety and driver assistance features are no substitute for the driver's responsibility to operate the vehicle in a safe manner. Always refer to the Owner's Manual for important feature limitations and information.

The 2026 GMC Sierra 1500 is available in eight distinct trims, each offering its own personality and purpose. The lineup includes the Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate.
