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. Off-road hardware and a unique suspension tune set the AT4 apart from the rest of the Sierra lineup, including the luxury-oriented Denali. The AT4 comes standard with skid plates and hill descent control, so you can take it on trails right off the lot.
