I have increased my EV range slowly starting from 13 miles when I received my PIP in April to a high of today of 17 miles. What are the highs and lows of everyone else. I am from Oklahoma and I have a round trip of 45 to 50 miles half on highway speeds and half at 50mph country roads. I love my PIP. I average from mid 50's to low 60's overall mpg.
