Qone0, in terms of pure physics, you are right. Driving faster is generally less fuel-efficient.

But the study was more about the effect the speed limit had on overall fuel consumption, not speed itself. (For example, hardly anyone actually drove at the speed limit of 55 MPH.)

Here's a link to the original report. It's over 400 pages, but you can peruse certain sections at your leisure:
