Miles Overview
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 AT4 sits above the Elevation as the off-road-ready trim, trading some pavement comfort for rugged capability with a factory lift, all-terrain tires, and skid plates. Under the hood is a Duramax 3.0L I6 paired with a automatic transmission and four-wheel drive, delivering strong low-end torque for towing and a claimed 19 mpg combined on regular diesel. The AT4 comes standard with an auto-locking rear differential, hill descent control, and a 2-speed transfer case, so you can tackle trails without needing to add a thing.
