New: Ford mods their Super Duty pickups ... chin spoiler + final drive changes

Via ABG & Pickuptruck.com

"Ford is replacing standard 3.73 ratio rear axles on certain F-250 and F-350 Super Dutys with 3.55 running gear and has lengthened the underbody chin spoiler by 100-mm (3.93-in)."



Quote:
Ford trucks spokesperson Wes Sherwood says, "We are making the 3.55 standard and when that's combined with new front-end aerodynamic improvements, there will be about a 1.5 miles-per-gallon improvement."

It's difficult to quantify the fuel economy improvement in percentage terms because three-quarter and one-ton heavy duty pickups aren't required to carry EPA mileage ratings. But this could mean as much as a 10 to 15-percent improvement for some drivers, depending on how they use their truck.

[...]


"Fuel economy is on people's minds right now and we're not going to wait until the next model year to make a change. We're going to implement changes like this as soon as we can."
