2026 GMC
Sierra 1500

GMC’s half-ton pickup doesn’t need to change much to remain a favorite, and thus it carries over its mechanics and amenities into the 2026 model year. Buyers have a new exterior option to elect, though. The new Black Badging Package is available on every trim except the base Pro, bringing a distinctive dark appearance with blacked-out emblems and accents. Elsewhere in the lineup, Coastal Dune and Glacier White Tricoat oust Titanium Rush Metallic, Thunderstorm Gray, and White Frost Tricoat from the color palette.

Underneath the updated exterior, the Sierra 1500 remains a segment leader in power and comfort, boasting best-in-class standard engine torque (430 lb.-ft.) and crew cab legroom (44.53 inches). The Sierra’s four available engines provide power and performance for work or play. The lineup’s five cab and bed configurations allow drivers to prioritize either crew or cargo (with seating for up to six passengers or beds exceeding 98 inches in length) while never sacrificing either. The Sierra’s dozens of packages prepare it for everything from plowing snow to hitting the trail, making it highly customizable and able to suit every driver’s individual needs.

Trims, Powertrains, and Performance

The 2026 Sierra 1500 comes in eight trims: Pro, SLE, Elevation, SLT, AT4, Denali, AT4X, and Denali Ultimate. The standard powertrain on the Pro, SLE, and Elevation pairs GM’s inline 4-cylinder TurboMax engine with an 8-speed automatic transmission, for an output of 310 horsepower and 430 lb.-ft. of torque. The SLT and Denali harness a 5.3-liter EcoTec3 V8 engine (355 horsepower and 383 lb.-ft. of torque) coupled with a 10-speed automatic transmission. The AT4 and AT4X upgrade to a 3.0-liter Duramax Turbo Diesel engine with a 10-speed automatic Electronic Precision shift transmission, netting 305 horsepower and 495 lb.-ft. of torque. The Denali Ultimate is equipped with a 6.2-liter EcoTec3 V8, generating 420 horsepower and 460 lb.-ft. of torque, married to the same 10-speed automatic Electronic Precision shift transmission found in the AT4 and AT4X.

A rear-wheel drivetrain (RWD) comes standard on the Pro, SLE, Elevation, SLT, and Denali, while the higher grades are outfitted with standard four-wheel drive (4WD), which is available for the entire lineup. The Pro, SLE, and Elevation’s TurboMax engine returns an EPA-estimated 18 mpg city and 21 mpg highway with RWD and 17 city/20 highway mpg with 4WD. The SLT and Denali’s 5.3-liter V8 yields 16 city/20 highway with RWD, dropping to 15 city/19 highway mpg with 4WD. The Duramax Turbo Diesel achieves 22 city/26 highway on the AT4 but drops to 19 city/20 highway on the AT4X. The Denali Ultimate’s 6.2-liter V8 returns 15 city/19 highway.

The Sierra’s fully boxed steel frame complements five cab and bed configurations. The three-seater regular cab is exclusive to the Pro, and can be paired with either the 79.4-inch standard bed or the 98.2-inch long bed. The six-seater double cab is available on the Pro, SLE, and Elevation with the standard bed. The crew cab, which seats five or six depending on the trim, is offered on every Sierra 1500 with the 69.9-inch short bed, and on all except the AT4X and Denali Ultimate with the standard bed. Every grade except the Pro has an automatic locking rear differential, while the AT4X boasts front and rear driver-selectable full-locking differentials. The Elevation rides on a high-capacity suspension, while the Denali and Denali Ultimate upgrade to premium suspension with continuous damping, Adaptive Ride Control, and selectable Sport Mode. The AT4 comes with Monotube Rancho shocks, which the AT4X swaps for Multimatic DSSV dampers, both on a 2-inch factory lift. The 4WD Pro, SLE, Elevation, and SLT have a single-speed Autotrac transfer case, while the AT4, AT4X, Denali, and Denali Ultimate have a two-speed transfer case. The AT4, AT4X, Denali, and Denali Ultimate also get an electronic transmission range selector with paddle shifters and hill descent control. Every trim comes standard with Tow/Haul Mode, and all but the Pro comes with an integrated trailer brake controller, along with the Trailering Package (available on the Pro), which adds a 2-inch receiver hitch, a 7-wire electrical harness with sealed connectors, and Hitch Guidance. The AT4 and higher grades include GM’s In-vehicle Trailering App (available on the SLE and higher). The Sierra 1500 reaches its 13,300-pound tow limit when the double cab and short bed houses the 3.0-liter Duramax Turbo Diesel paired with RWD.
