2026 GMC Sierra 1500 SLT

When it comes to raw pulling power, the 2026 GMC Sierra 1500 stands out from the crowd. The SLT comes standard with a 5.3-liter V8 engine paired with a 10-speed automatic transmission, and the available Duramax 3.0-liter Turbo-Diesel engine unlocks a maximum towing capacity of up to 13,300 pounds when properly equipped.

The TurboMax engine delivers best-in-class standard torque of 430 pound-feet, giving you the confidence to haul heavy loads without breaking a sweat. An available ProGrade Trailering System further streamlines the hitching and towing process with integrated tools designed for commanding control on every trip.

Step inside the Sierra 1500 SLT and you'll find a cabin that takes comfort seriously. Best-in-class standard Crew Cab front head- and legroom gives every passenger room to stretch out and relax. The SLT elevates the experience with 10-way power front outboard seats with power lumbar adjustment and perforated leather appointments that feel premium without being flashy.

Chrome grille accents, door handles, and front and rear bumpers carry that polished look inside and out, while smart and ample storage keeps your gear organized without crowding the space you need.

The 2026 Sierra 1500 SLT puts a wealth of connected technology right at your fingertips. The 13.4-inch diagonal multicolor touchscreen serves as the hub for the GMC Infotainment System with Google built-in compatibility and voice-activated controls.

A 12.3-inch diagonal Driver Information Center keeps key vehicle data clearly in view, and up to 14 available camera views make navigating tight spaces or maneuvering a trailer a far less stressful experience. The available ProGrade Trailering System takes the guesswork out of hitching up, and the over 40-inch diagonal of combined driver-focused digital displays delivers the most in its class.

The Sierra 1500 SLT is equipped with GMC Pro Safety features that work quietly in the background to help keep you and your passengers protected. This suite includes collision-avoidance and driver assistance technologies that enhance your overall awareness behind the wheel.

Hill Descent Control is available for controlled descents on steep grades, and Front and Rear Park Assist helps you navigate tight spots with added confidence. Safety or driver assistance features are no substitute for attentive driving, but these tools offer a meaningful layer of support on every journey.

The 2026 GMC Sierra 1500 lineup offers eight distinct trim levels, each crafted to meet a different set of priorities. The Pro starts at $38,300 and serves as the hardworking foundation of the family. The SLE adds a 13.4-inch touchscreen and heated front seats, while the Elevation brings a bold monochromatic exterior with gloss-black accents.

The SLT steps up with a 5.3-liter V8 and chrome exterior trim for a polished presence. Off-road enthusiasts will appreciate the AT4 with its 2-inch factory lift and Rancho monotube shocks, and the AT4X pushes further with front and rear electronic locking differentials not offered on any competitor in its class. At the top, the Denali and Denali Ultimate deliver luxury-grade appointments, including available Super Cruise hands-free driver assistance technology.
