Here in the northwest the weather has been dry and temps in the 40's to over 60 degrees. The mpg's have increased about 5-7 mpg over just a month ago. So far with about 230 miles the mpg gauge is reading 57.6 mpg for about a true 54 mpg calculated. Dry weather and an increase in temp's make a big difference in a Prius more than any other car I have owned and I been driving since 1966.
Indeed , here in the Northeast too. Just broke my last years top MPG with 64 indicated, 62 actual mpg, on a round trip 200 miles ride. Avg mph was 42 , so this was no slow motion hypermile. Going to be a great summer now that the car is broken in at 35Kmi. I guess its 60 mpg at 60 mph if 60 Degrees .
It's been a good year so far... My actual MPG last 56.5, 54.5, 54.5. Worst was 44.9 in January, and ytd avg is 51.25
I noticed a 5.5 mpg increase. Now at 50 mpg. Considering the hills here I am impressed. We are taking the first extended trip tomorrow to the coast. I am interested to see how it does on the highway.
