Miles Overview
The 2021 Sierra 1500 is GMC's full-size pickup, offered in work-oriented and luxury trims that range from the Elevation to the Denali. It lines up against the Ford F-150, Ram 1500, and Chevrolet Silverado 1500, with the Denali aiming at the luxury end of the segment. The Sierra drives with a composed, planted feel, and the steering is precise for a truck of this size. The cabin is roomy and well built, and the available MultiPro tailgate adds useful versatility for loading and reaching the bed. The SLT skips the Denali's extra chrome and luxury touches but keeps the leather interior and heated seats, saving you thousands. Its 5.3L V8 makes 355 horsepower and 383 lb-ft of torque, paired with an eight-speed automatic and four-wheel drive that handles towing and snow without fuss. The MultiPro tailgate is standard here, giving you six ways to load, step, or reach into the bed without climbing over the side.
