If the Explorer would behave normally I would have no complaint: a normal car loses 1 MPG per each 5MPH gained, so if it is getting say 30MPG at 50 it should then get 29MPG at 55, and 1 more 55 to 60 so now 27MPG and then 60 to 65MPH and again 1 MPG lower so now we are getting 26MPG, 70MPH is 25MPG and 75 is 24MPG and 80 would be 23MPG. Perhaps a little more as wind is squared.
My two cars a 2000 Mercury and 2003 Crown Vic FOLLOWS that kind of a stead MPG drop.
This Truck does also ONCE they have taken 10MPG off at 60MPH.
30 MPG at 50MPG and 1500RPMS, 60 and boom 18MPG...then 1MPG per 5 MPH and will then do at 80MPH 16MPG....
That just is not right.

It was a mild hybrid. With the hybrid system disabled (the battery removed, running only on the ICE) the highway fuel economy was the same, but city fuel economy dropped a bit. It wasn't fully integrated like a Prius, it was just a small torque assist when you mashed the throttle. It was manual transmission.
Possibly part of the issue with the Explorer is camshaft related - some kind of torque island issue?
