Definetly not AWD but it is a 3.5l (v6). Does your sticker say 22 mpg hwy or 25? Also is this 20-22 just hwy or average? I am averaging 21.9 mpg for the last 17k miles. Everyones driving habits are different. I don't beat EPA city avg very often. My truck said 14 mpg city and got 12.5. My edge says 19 mpg and I get 17-17.8. But I get at least sticker (maybe +1) on the hwy. Driving habits and local terrain/trip terrain make a huge difference.

Went ahead and looked it up anyway...your 2008 AWD Edge is rated 22 mpg Hwy. So you are getting good numbers. The 2012 AWD Ecoboost is rated at 28 hwy if you are going back that route. Good luck and let us know how it goes. They have definetly improved these vehicles in the last few years.
