The 2024 GMC Sierra 3500 HD is built for serious hauling. It starts with a 401-horsepower 6.6-liter V-8 gas engine, but 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. Both pair with a 10-speed automatic transmission.

The standout feature is towing capacity: the Sierra 3500 HD can handle up to 36,000 pounds, far exceeding lighter heavy-duty competitors. For towing, the truck includes smart features like Transparent Trailer View, Trailer Side Blind Zone Alert, and available adaptive cruise control with trailering to make the job easier.
