I did measure (A-B-A comparison) that the Mustang got the same mileage at 55 as it did at 70.

The Fusion is an automatic, and it won't go into top gear below 45 or so, since the throttle load will keep the transmission in a lower gear, or at least out of lockup (not sure which) above 45 or so she gets very happy at low rpms.
That you got the same mileage at 55 and 70 makes 0 sense to me. At 70 your fuel consumption should have dropped like a rock. At 70 you should be experiencing a LOT more wind resistance.
