Description for 2026 GMC Sierra 1500 SLT Truck

The 2026 GMC Sierra 1500 SLT with the Duramax turbo-diesel engine and 10-speed automatic transmission is a full-size crew cab pickup built for long-haul capability, refined interior comfort, and off-road adaptability. Equipped with a 4WD system and the X31 Off-Road and Protection Package, this truck is suited for drivers who require both on-road civility and trail-capable performance.

The 3.0L Duramax Turbo-Diesel engine is engineered for torque and fuel efficiency, enabling the Sierra 1500 SLT to deliver strong towing performance while offering impressive fuel economy at an estimated 22 mpg in the city and 26 mpg on the highway. The powertrain is supported by a 170-amp alternator, auxiliary external transmission oil cooler, heavy-duty air filter, and a robust trailering setup that includes the ProGrade Trailering System, Hitch Guidance with Hitch View, Trailer Camera Provisions, and an Integrated Trailer Brake Controller. With the In-Vehicle Trailering App and Trailer Side Blind Zone Alert, trailering is designed to be safer and more user-friendly.

This SLT model includes the X31 Off-Road Package, which incorporates an off-road suspension, hill descent control, and skid plates to help protect vital components during uneven terrain navigation. Rear wheelhouse liners and the included spray-on bedliner with GMC logo add further durability. The inclusion of chrome assist steps and perimeter lighting adds utility and accessibility, especially in low-light conditions.

Interior features focus on comfort, connectivity, and utility. The Dark Walnut/Slate leather-appointed seating includes heated and ventilated front seats, as well as heated second-row outboard seats. The front bucket seats are divided by a floor-mounted center console, and the SLT Convenience, Preferred, and Premium Plus Packages bring together premium elements like wireless charging, a premium Bose 7-speaker audio system, and a power rake and telescoping steering column. Technology features include a Wi-Fi hotspot, wireless smartphone charging, and multiple USB ports (charge-only and data-enabled) throughout the cabin.

The SLT trim is also equipped with advanced driver-assistance and safety technologies as part of the Sierra Safety Plus Package. This includes adaptive cruise control, rear cross traffic braking, rear pedestrian alert, ultrasonic front and rear park assist, a safety alert seat, HD surround vision, and a high-definition rear vision camera. Features like the electronic precision shift, keyless open and start, and push-button start provide a modern and convenient driving experience.

The cabin also benefits from thoughtful climate and visibility features, such as the electric rear-window defogger, rain-sensing wipers, and dual-zone automatic climate control. Additional touches like the universal home remote and remote vehicle starter system enhance day-to-day functionality.

This 2026 Sierra 1500 SLT is finished in Summit White with chrome exterior accents and deep-tinted glass, contributing to both aesthetic appeal and cabin privacy. LED cargo area lighting, multiple 120-volt outlets (bed-mounted and interior), and a power sliding rear window with defogger further bolster its work-ready versatility.
