With its aluminum construction being much lighter than the current model, the 2015 F-150 should have a significant increase in fuel economy.
However if you're just comparing 5.0 to Ecoboost, you won't see much difference in fuel economy. I have 3 different friends and family with Ecoboost F-150s and none of them get more than 15mpg average, and no better while towing than you get now. The biggest advantage of the Ecoboost is power, not fuel economy. If you are very light of the pedal, the Ecoboost will get great mileage, but step on it at all, and those turbos are sucking alot of air, negating much benefit of a smaller displacement.
One of my family members traded his Ecoboost F-150 for a hemi Ram 2500, without that much difference in fuel economy for him.
I agree that fuel mileage is not the selling point of the Ecoboost. However, I am beating your three friends in that department. Lifetime (mixed driving and some towing, over 5,000 miles) I'm at 16.9mpg. In a 1,000 miles of my work commute, without towing, I average right at 19mpg. Not bad for this kind of power in a 3 ton 4x4. It is getting just better than my old Chevy V8, and making twice the power!
It will also tow my TT at 60mph in 6th gear at 1600rpm. Much more relaxed. Even pulling a 6% grade it drops to 5th at 2000rpm. I used to do that same hill screaming at 4000rpm and loosing speed.
If I get long term reliability out of the ecoboost, it will turn out to be one hell of a truck. If...
