Ford’s second-generation 6.7-liter Power Stroke® V8 turbo diesel now boasts 440 horsepower, up from 400 horsepower, and 860 lb.-ft. of torque, up from 800 lb.-ft, across all Super Duty models from F-250 to F-450.
The 2015 F-450 tops the F-Series Super Duty pickup truck lineup with maximum towing capacity increasing to a class-leading 31,200 pounds, a gain of 6,500 pounds. The truck’s gross combined weight rating increases to a class-leading 40,000 pounds, a gain of 7,000 pounds.
F-350 increases maximum towing capacity as well, to 26,500 pounds, from 23,200 pounds, and the gross combined weight rating goes up 5,000 pounds to 35,000 pounds.
The improved ratings are a result of designing and engineering the truck as an integrated system. The approach enabled Ford engineers to optimize performance across the full Super Duty lineup.
• Second-generation 6.7-liter Power Stroke® V8 turbo diesel boosts horsepower to a class-leading 440 horsepower; torque to class-leading 860 lb.-ft. for all models
• F-450 chassis upgrades raise maximum gooseneck trailer towing capacity to class-leading 31,200 pounds, fifth wheel towing capacity to class-leading 26,500 pounds, and gross combined weight rating to a class-leading 40,000 pounds
• F-350 available with maximum towing package that increases fifth-wheel/gooseneck trailer towing capacity to 26,500 pounds, and raises the gross combined weight rating to 35,000 pounds
“The 6.7-liter Power Stroke was already a stout engine,” said Robert Fascetti, Ford vice president powertrain engineering. “The improvements we’ve made essentially give Super Duty customers an engine designed for our larger F-650 and F-750 trucks. They may not realize how tough this engine really is.”
