Well regarding the higher price of gas in Europe, you might ring up your elected officials and suggest you have had it with the whole tax thing!
Back to the MPG issue, it does seem like the 15.6 is low but the again, if you are sitting on the strip in Vegas on Saturday night, that is not that bad.
Ditto, blasting through the desert at say 110 MPH.
If you are doing 70 MPH steady, you have an issue. My Box S's usually will get 25 or so at steady highway speeds. Much less in town of course.
Hope that helps.
