The mileage in my Edge (FWD) has been very consistent and predictable. If I'm driving my normal surface street commute, it's generally around 20 MPG +/- 1 MPG depending on whether traffic has been generally heavy or light. I've only had one tank that has gone below the 19 MPG city sticker rating. If I add in extra freeway miles, it quickly jumps up towards the 24 MPG range. I haven't done any long road trips with my Edge because I have limited lease miles, but I could easily see approaching the 27 MPG highway rating. That said, I'm planning on going hybrid for my next car since my driving is city heavy and I rarely need the full capacity of the Edge.
