My 2012 Prius V is averaging via the dash 39.1 mpg in mixed driving with many shorter trips. It has dropped since Florida weather high temps have gotten back into the lower 90s and humid. This car has no tinting whatsoever and the AC is working harder. I do have to say this car has one of the coldest AC systems I've owned. I sometimes have to raise the temp setpoint to not feel too cold when it is blasting away when I first get into it when it's hot out. I saw as high as 41mpg (average) when it was cooler out this winter in FL. I drive it like a normal car when in traffic altough I coast with no one behind for a stop. I am very happy with it.
