I'm getting on the order of 26 MPG on my Green Line with what's more or less 80% suburb driving (in Metro DC). Highway mileage is much better than EPA, but the "city" mileage is more like 20 MPG for me so far.
I've only got just over 1200 miles on it so far. It'll be a couple of weeks before I get a good long highway run to see how well it performs versus the sticker.
It's easily 30% improvement over the MPG I was getting on my conventional Vue.
