Since this information was obtained during real world conditions over a full battery charge I consider this information to repeatable and indicative of all FFEs. This information was extremely useful to me on my cross country trip keeping me from ever running out of charge over the 1,800 mile trip with some very challenging charging conditions. Now that I have purchased a 2017 FFE I decided to try to extrapolate the data I obtained on my 2013 model.

I used the data to form fit a third degree polynomial equation based on the four data points. The results very closely matched my measured data point so I decided to share my results. The results of the equation based on 95% usage of 28.8 kWh measured on my battery draw down test are as follows;
