2018 prius I can average 75
2018 prius I can average 75 on a 15 mile round trip in the summer I've got 100 over 7 miles same road. It loves 30-45 mph zones. If you switch to nutrel while coasting (when in EV mode) your mpg will go way up. Usually I am driving to work at 67 mph and I get about 48 over 20 miles in winter mornings 60 on a nice summer day. It hates the cold. Black interior probably helps the battery in winter sometimes.
