2026 GMC Sierra 1500 SLT

The Sierra 1500 is GMC's full-size pickup, offered in trims from the work-oriented Pro to the luxury Denali Ultimate. It competes head-to-head with the Ford F-150, Ram 1500, and Chevrolet Silverado 1500. The Sierra drives with a composed, planted feel, and the available adaptive suspension smooths out rough pavement nicely. Cabin space is generous, with a roomy crew cab and a bed that handles serious hauling duties. A large touchscreen with wireless Apple CarPlay and Android Auto comes standard, along with a full suite of driver assists. The SLT is the luxury middle ground of the Sierra lineup, giving you leather seats and the MultiPro tailgate for less than the Denali. Its standard 5.3L V8 pairs with a ten-speed automatic and four-wheel drive, delivering strong towing confidence. Pick the Duramax 3.0L Turbo-Diesel option and you'll get better highway range and the same smooth ride.
