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. The AT4 is the off-road-oriented Sierra 2500HD, so you get skid plates and an off-road suspension that the Denali doesn't have, but you give up some of its chrome and leather. Its 6.6L I8 makes 401 horsepower and 464 lb-ft of torque, paired with a six-speed automatic and four-wheel drive, which gives you confident pulling power for heavy trailers. The AT4's unique suspension tune and Rancho shocks let you tackle rough trails, but the ride is stiffer on pavement than the SLT's.
