I too am getting no where near the 47 mpg that Ford uses in their advertisements. I have 7000 miles on my 2013 Ford Fusion. I am lucky to get 37 mpg. I took it into the dealer who did a fuel economy test of their own. They got 34.7 mpg, the dealer, not me. And they told me that the car test normal and there is nothing they can do. So, running normally, I am told that I can expect 34.7. Called Ford Customer Service to express my dissatisfaction with the gas mileage. Was told that the gas mileage varies due to the way the car is driven. When I told Ford it was the dealer that got 34.7 not me, they just said there was nothing they could do. They said that it is the EPA that says the car gets 47 mpg not them. What a cop out. They use it to sell the car and hide behind it when their cars underperform. To me this car is a lemon. 20% less gas mileage than advertised. My family has been buying Ford products for over 50 years. It is a shame that Ford does not stand behind their products anymore.
