That is a nice prediction coming from a former 12 owner. The highest prediction I ever saw was 47 out of mine. My 2016 predicts 67 as of now. My family and I drove to the Smokey Mountains a few days ago. Using my initial charge, I got 71 miles, then I was able to get about 3.5 hours of free charge at an outlet called "Tanger" and then we drove to the top of Clingmans Dome and got 4 bars coming back down the mountain. All in we drove 354 miles and used 5.1 gallons of gas. Let anyone try that in the mighty "I mean dorky" Prius.
