Miles Overview
The 2023 Sierra 2500HD is GMC's heavy-duty pickup, built for serious towing and hauling with a choice of work-oriented and luxury trims. It squares off against the Ford Super Duty, Ram Heavy Duty, and Chevrolet Silverado HD, each offering similar capability. The steering is direct for a truck this size, and the ride is composed when empty, though it can get busy over rough pavement. Crew cab models offer a roomy back seat, and the Denali's interior brings real luxury with premium materials and quiet comfort. Standard tech includes a large touchscreen with wireless Apple CarPlay and Android Auto, plus available head-up display and camera mirror. Stepping up to the AT4 from the SLT adds off-road hardware like a two-speed transfer case, skid plates, and Rancho shocks, plus unique styling inside and out. The 6.6L V8 makes 401 horsepower and 464 lb-ft of torque, routed through a six-speed automatic and four-wheel drive, giving you confident pulling power from a stop. The AT4's off-road suspension tune gives it more wheel travel than other trims, which helps on rough trails but adds some body motion on pavement.
