- 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
UPPER MARLBORO, MD, 2014– Ford F-Series Super Duty reinforces its leadership in the heavy-duty pickup truck market with engine and chassis upgrades for 2015 that together deliver best-in-class horsepower, torque and towing capacity.
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 classleading 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 4,500 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.
“Our chassis people work in unison with our powertrain people to develop more than a great truck, it’s a machine engineered for work,” said Marc Bortnick, Part Owner & General Manager of Upper Marlboro Ford.
“We’re the only manufacturer that develops and builds our own powertrains in this class and when you combine that with a chassis that’s purpose-built for best-in-class power and torque, you can feel the result in the way it drives, especially when towing big loads.”
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 Marc Bortnick of Upper Marlboro Ford. “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
Enhancements include a larger turbocharger for faster air displacement resulting in more power. The engine block is made of compacted graphite iron, which is stronger yet lighter than cast iron, is more wear-resistant and has enhanced sealing properties.
New injector tips spray a finer mist of fuel into the cylinders which provides a more complete burn and helps reduce noise, vibration and harshness. Other benefits include lower emissions and less fuel deposit buildup on the intake valves over time.
The engine enhancements give the Power Stroke engine a classleading maximum output of 440 horsepower and 860 lb.-ft. of torque.
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.
