I have a 2012 purchased begining of April /12, we have 2600KM = approx 1600 miles. We average 33-34 mpg or 8.6L/100km in the metric system. After 60 mph fuel milage will increase as speed increases. we drive mostly around 62 - 65 mph or 100 - 106 kilometers/ hr. We are very satisfied with the Edge, had a faulty coolant hose clamp that at 16psi coolant pressure, it would be noticed by the odor, never saw any dips. I also noticed black at the tail pipe, I was told by the dealer that is common during the break in time , should clean up after 5 - 7000 miles.
