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

Power Stroke Engine Improvements
The 2015 Super Duty achieves best-in-class towing performance with a second-generation 6.7-liter Power Stroke V8 turbo diesel engine that was further developed to provide more power, torque and efficiency.
“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.”
Key innovations on the 6.7-liter Power Stroke V8 turbo diesel are its compacted graphite iron engine block and reverse-flow layout. This segment-exclusive design places the exhaust inside the engine’s V-shape, with while the air intake positioned on the outside resulting in a variety of advancements:
Shorter airflow from the exhaust system to the new, larger turbocharger sitting between the engine’s cylinder banks improves turbo responsiveness – key to providing torque quickly to truck customers when they need it most
Positioning the turbo inside the engine’s valley helps isolate the engine’s hottest temperatures, improving performance and efficiency, while also reducing noise, vibration and harshness to improve driver comfort
The F-350 is available with a high-capacity towing package that includes new front springs and a wide track axle, increasing the gross combined weight rating with the 6.7-liter Power Stroke engine from 31,900 pounds to 35,000 pounds.
Improvements to the F-450 that allow it to handle the increased tow rating include commercial- grade 19.5-inch wheels and tires; upgraded rear U-joints and suspension components, including new rear leaf springs; front and rear stabilizer bars; and shocks. The steering system has stronger gears and linkages and the fifth-wheel/gooseneck has an increased towing capacity. The brakes are larger and feature new antilock calibration for enhanced performance.
