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 and below the Denali, bringing genuine off-road hardware like the two-speed transfer case and Rancho shocks instead of street-focused luxury. Under the hood is the 6.2L Ecotec3 V8 paired with a ten-speed automatic and four-wheel drive, delivering strong passing power and a deep V8 rumble that suits the truck's rugged character; expect 15 mpg combined. The AT4's 2-inch factory lift and underbody skid plates mean you can tackle rough trails right off the lot without aftermarket work.
