My 2005 #6 Prius normally gets between 48 - 51 mpg running around my own area but last weekend I took a longer trip via interstates and got 56 mpg. So I got about what you got. It feels rrrreeeeeeeaaaaaalllllllly good, doesn't it? :mrgreen:
I have a friend who lives in a cold, snowy winter climate and she says her 2003 Prius' mileage drops from around 45 mpg to around 30 mpg. I am hoping that since Tennessee's winter climate is much more mild that my car's winter mileage will be better.
