The MPG-e of this vehicle is so different on long distance trips with little opportunity to charge the EV battery pack versus local driving where 50% to 66% of your driving can be in EV only mode I think it is important to maintain a separate log for this kind of driving in the new year (2017). Any long distance trips will be kept on the original C-Max Energi log. The electrical consumption translated to gals-e will be done on both logs.
