I see nothing amazing here. My neighbor just bought an F150 Ecobust and he was so proud of it...until we hauled some cattle to market. We had the same load in identical trailers and his over heated His fuel mileage was just over 6 mpg for the trip. My old F100 with a modded 410 didn't hardly break a sweat and got 14 mpg. My 4.6 Supercrew also beats him going down the road empty. He gets into the 17 mpg and I'm running at 23-24 mpg right in front of him. But what's really bad, my brothers GMC 5.3 gets better mileage than I do and his is a 4x4. The GM blocks are hard to beat for power, torque, and fuel economy. I'd have one quick except the rest of the truck is such crap. At 40,000 miles bro has had the front axle replaced, the transmission replaced, the power steering replaced and some other parts in the front end. It's currently sitting in a barn with an electrical issue that kills the battery over night and the starter won't engage. Replacing the starter and all of the components didn't fix it.But to see a GM block get great fuel mileage is a common thing.

Just get a Toyota Tundra with the 5.7, change the oil on time and keep air in the tires and be done with it.

It seems a low rated fuel economy would definitely be the obvious winner. A car that gets 1mpg increasing to 2mpg would win over a 50mpg vehicle getting 99mpg.

Not surprising... my son has a 500hp Corvette that can cruise in 6th gear at low rpm and get better mileage than my little S2000 four banger.
