New 2013 Fusion Energi with ~600miles on it and I can't seem to squeeze more than around 16miles out of EV before it kicks over to hybrid. That is with my standard commute averaging 60mph w/ very little traffic. Trying really hard to drive slowly/gently, maximize braking, and even turning the climate control off completely for the trip. (turning of climate control does seem to improve range by ~1mile). I'm using the 120v charger provided with the car. My questions, will this improve over time? am I doing something wrong? did I get a bum battery pack?
