I was thinking the same thing. By the time OBX and BB owners opt for the rear locker and most everyone swaps out the passenger tires, we will all be in the same soup.I have the OBX and its better mileage . . . Except i don't! I opted for the rear locker, and that changed the axle ratio from 3.73 to 4.27. I doubt EPA tested this version.
I'm guessing that the primary reason for the mileage drop in the BD is the axle ratio, not the weight. The BD has the 4.46 axle with the rear locker. The weight of the plates counts, I'm sure. But i regularly get 24mpg Highway on my F150 with the 2.7 ECO, and its lots heavier than the Bronco. Same 32" tire diameter. But i have 3.55 axles, not the tow friendly 3.73 or 4.27.
We can all compare next year in real life. But axle ratio is a big factor, along with tire size, in mpg. IMO. The reason the Sasquatch isnt worse is that the diameter of the 35" tires counters the 4.7" axle ratio. (And v.v.)
