In my experience, you will see about 2-3mpg FE improvement for every 5 miles per hour slower you go - all the way down into the 40mph range. AC use is also a FE killer.

Enjoy.
Excellent chart and it overlaps the data from the CleanMPG thread. Tonight I'll try to combine both sets. Your 65 MPG at 55 miles per hour is in good agreement with the CleanMPG data. Funny how only at GreenHybrid.com do we find a Prius driver combining HCH MPG vs MPH data. <grins>
