Jumped in my wife's Edge to check the oil and noticed that while not a long trip she just did a round trip of about 15 miles with that short trip showing 28.5 mpg. We live in a very hilly/mountainous area so even that 15 miles had some nice climbs, curves, flats, and descents. My 05 F150 could take a few lessons from these new motors and their associated technology.
We have also found that using the adaptive cruise when on bigger open roads gives the best mpg, as the slow downs and speed ups are really smoothed out preventing the engine from wasting fuel from harsh changes in speed.
