Performance & Capability

Engine Performance

Both heavy-duty versions of the 2023 GMC Sierra offer the same engine options. First up is a naturally aspirated 6.6-litre V-8 gasoline engine, making 401 horsepower and 464 pound-feet of torque. Buyers needing more torque for maximum towing capacity can choose to equip their truck with a turbocharged 6.6-litre, V-8 diesel power plant, making 445 horsepower and 910 pound-feet of torque.

HD Support Features

Simply dropping a powerful engine and transmission in a truck isn’t enough to make it heavy-duty. It also needs to be supported with the right components. AT4 and Denali models are equipped with responsive suspension systems for optimal wheel alignment, ride comfort and maneuverability. Diesel-powered 2023 Sierra HD trucks achieve optimal engine performance thanks to a massive 28-inch variable-speed cooling fan directing cool, dense air through the engine.
