I'd heard that the new Prius V would give you stats on your latest trip. I see where it will tell you how long you've driven, but I was under the impression that it also did your MPG for the latest trip too? Also, my 2008 would automatically reset the trip odo upon fill up. Not the tripA or tripB odo's, but the one on the consumption screen. Does the new one do something similar? I new at every fill up that I would reset the MPG's for that tank whenever the miles reset. I can't find an analog to that in the new screens. How are people calculating MPG's per tank, computerwise?
