I just found this site. I've had my Prius V since August 18. I got the V so I could get my road bike in the back without taking off the front wheel. After 4 fill ups I'm getting right around 45 mpg.
Now the fun begins...Never paid so much attention to fuel economy before our "v".. Our is 32 months old and 32K.. Still impressed with how easy it achieves great fuel economy...
