The Ford F-Series Super Duty is a potent pickup.

For many, a pickup truck is as much a daily drivable vehicle as it is a tool for getting the job done. How much horsepower and torque a powertrain puts out is a big part of that. Most want enough to get the job done while keeping an eye toward fuel economy.

What's the difference between horsepower and torque? In simple terms, torque is the pull of the powertrain that gets you off the line from a full stop. Horsepower is what gets you going the speed you want and keeps you there.

Diesel engines tend to have more torque than gasoline-powered engines but have less horsepower. There's no perfect torque to horsepower ratio. It's all about which combination works best for you.

The engines on this list have the highest amount of horsepower and are available in 2021 model year pickup trucks in the U.S. See the 2020 horsepower champs by clicking here and the 2020 torque winners by clicking here.

Those numbers are good enough to help the truck deliver a 13,300-pound towing capacity and a 2,060-pound payload rating.
