 I've had the Edge for two years.I have yet to get 27 mpg on the highway BUT it seems the gas mileage gets better all the time.It started (using what the vehicle's posting) at 18 mpg and it is up to 21.4 mpg with mostly city driving.I had an issue with the syncmyride - my dealership manager worked with me to make sure it was corrected - I had to get another phone before it worked correctly BUT then after the computer was updated that phone did not work!Then Ford said to look at the list of phones that were compatible with the car.And lo and behold after I bought the compatible phone it has been smooth sailing every since.My phones were all basic phones so the costs were minimal.
