The 2024 GMC Sierra 3500 HD is built for serious towing and hauling. It comes standard with a 401-horsepower 6.6-liter V-8 gas engine paired with a 10-speed automatic transmission. If you need maximum power, you can upgrade to the available 6.6-liter Duramax turbo-diesel V-8, which delivers 470 horsepower and an impressive 975 pound-feet of torque. The diesel option unlocks the Sierra 3500 HD's maximum towing capacity of 36,000 pounds-far exceeding what other heavy-duty trucks can handle. Both engines work with responsive transmissions and offer rear-wheel or four-wheel drive. For those who regularly tow heavy loads, the Duramax is an excellent choice.
