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. Off-road hardware and a factory 2-inch lift set the AT4 apart from the SLT and Elevation trims. Its standard Duramax 3.0L Turbo-Diesel pairs with a ten-speed automatic and four-wheel drive, earning 19 mpg combined. Rancho monotube shocks and an automatic locking rear differential come standard, so this truck feels planted on loose trails.
