The 2024 GMC Sierra 3500 HD offers two powerful engine choices. The standard 6.6-liter V-8 gas engine delivers 401 horsepower and 464 pound-feet of torque paired with a 10-speed automatic. For maximum power and towing, you can upgrade to the available 6.6-liter Duramax turbo-diesel V-8, which generates 470 horsepower and 975 pound-feet of torque-also with a 10-speed automatic transmission. Both engines are refined and responsive, making the Sierra HD more agile than comparable heavy-duty trucks. The diesel is ideal if you regularly tow heavy loads.
