Ford promises best-in-class towing capacity.

Ford made small but meaningful improvements to the F-Series Super Duty for 2018. While most of the tweaks are invisible to the naked eye, buyers who regularly tow or haul heavy loads will notice them right away.

Developed in-house by Ford, the 6.7-liter Power Stroke turbodiesel V8 engine gets a redesigned cylinder head and calibration changes to the fuel delivery and turbo systems. It now makes 450 horsepower and 935 pound-feet of torque, increases of 10 across the board. Ford claims both figures put the F-Series at the top of its segment, ahead of rivals Chevrolet and Ram.

The updated eight-cylinder gives F-Series owners the ability to tow 34,000 pounds with a gooseneck hitch or 21,000 pounds with a conventional hitch. The rear-wheel drive F-450 model can tow up to 7,360 pounds.

Auto-makers aren't required to publish fuel economy figures for heavy duty-trucks. We don't know what effect (if any) the changes have on efficiency.

The 2018 Ford F-Series Super Duty is scheduled to arrive in showrooms across the nation in the coming weeks. The line-up is broken down into four basic trim levels called XL, XLT, Lariat, and Platinum. Pricing starts at $52,830, including a mandatory $1,295 destination charge.
