Lots of people have been complaining about MPG on their new Fusion. I am getting around 24 average MPG, and live in Minnesota where it has been below zero every night since I bought the car! I went from a F150 with ecoboost to the Fusion because of the bold design, AWD, and did not have the use for the truck anymore.
People need to give their new car a little more time before it starts producing the rated MPG. It doesn't happen in the first tank of gas.
I am happy with every feature Ford has put in to the redesigned Fusion!
