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 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.”
