The 2024 Sierra 3500 HD offers two powerful engine choices. The standard powertrain is a 6.6-liter V-8 gas engine with 401 horsepower and 464 pound-feet of torque, paired with a 10-speed automatic transmission. For maximum capability, you can upgrade to the 6.6L Duramax turbo-diesel V-8, which produces 470 horsepower and 975 pound-feet of torque, also with a 10-speed automatic. Both engines are refined and responsive, and you can choose between rear-wheel or four-wheel drive. The Duramax diesel is ideal if you regularly tow heavy loads.
