Don't the EPA tests assume aerodynamic drag based on numbers that are furnished by the automakers? I think this could affect their wind tunnel numbers that they furnish, therefore affecting EPA highway MPG.
That said, I am very suspect of the Equinox claims of 31 highway; I wonder if they fudged their aero numbers a bit. We'll see by next year what drivers get.
