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 AT4X gives you the off-road hardware of the AT4 but adds Multimatic DSSV dampers and front and rear locking differentials that the standard AT4 skips. Its Duramax 3.0L Turbo-Diesel makes 305 horsepower and 495 lb-ft of torque, with the ten-speed automatic shuffling power smoothly on the trail; expect 19 mpg combined in mixed driving. Only the AT4X comes with a factory-installed two-inch lift, AEV stamped-steel front bumper with winch capability, and 33-inch Goodyear mud-terrain tires as standard equipment.
