Friend of mine had a 2012 Limited (Sterling Grey, sunroof and some other stuff) for a rental in Florida this week. He was sending us updates on his experience with the car as my wife is in the market for one.
He very much enjoyed driving the vehicle. The V6 was peppy and moved the vehicle well. The seats were extremely comfortable, the ride was super smooth and quiet, except for one noise in particular. He described the noise that he wasn't sure where it was coming from, but it sounded like it might be the all too famous A-pillar buzz. One thing he has been impressed by is the mileage.
Keep in mind, that my friend isn't a lead foot, but he generally drives briskly and with purpose. He is not one to feather the throttle, but neither does he floor it from every stop, lol. The first tank gave 22.6MPG. This was with 65-70 on the freeway and Miami traffic, not sure of the mix of highway/city though.
While driving back from Key West to Miami, going 45-55mph, the trip computer got to 30.1mpg for a while. When he went to fill the tank again (a short fill, only 4.44 gallons added), the trip computer said 29.2mpg, but when he calculated the mileage, it was 30.16mpg!
His final tank, driving 65-70, gave him an average of 24.41mpg. He was very pleased and surprised. He wishes his 2012 Edge Sport did as well.
Total miles traveled= 791.2
Total gallons used = 32.467
Total Average MPG = 24.37
Not bad for such a large vehicle. This was also with 2 persons on board, with their luggage.
So lesson here is, drive 45-55mpg, and you will get excellent mileage.
