I don't have a RAV4 but I do
I don't have a RAV4 but I do have a Tucson plug in.
The Tucson does not include battery usage in mileage (mpge) and I suspect the RAV4 does the same.
That means even if you climb a steep hill in electric mode, you'll see 999mpg avg until the gas engine kicks on at some point.
Can anyone confirm/deny this about the RAV4 prime?
