I got my 2014 Fusion Energi back in June....to be honest, I have never changed the way I drive and because nobody really educated me that the # of miles one gets on a charge depends on your driving efficiency, I never knew I needed to. I always thought that I'd get 21 miles per charge and that's that. Now that I've said that, up until the weather has gotten cold, I was getting between 18-20 miles on a full charge. Some times I'd get 21-25 miles but that was rare. Again, my braking sucks...now that the weather is cold outside, it says I'm fully charged, the car shows 19 miles available, and I rarely even get 15 miles on a charge now. Is this because of the cold weather or because of my poor driving habits. I drive fast, I brake hard, and don't pay attention to the driving coach, etc. Is it even possible now to get my range back up to where it was and where other people are saying they're at, jsut by changing my driving habits, or is the damage done? Thanks!
