Am I incorrect in thinking that some time in the last year the EPA revised their mileage calculation models? I remember seeing revised ones for my Civic and being happy that I was surpassing them, but now Fuelly makes me feel all inferior again..
The EPA data we list is fresh from the fueleconomy.gov site, as of last week. I noticed with my own cars, the estimates seem to fall into newer reduced estimates (I think the EPA changed their criteria a year or two ago). So I'm pretty sure the data is up to date, but if there has been any more recent updates, as soon as the EPA updates their free data sources, we'll update them on our end.
