Well concerning the EPA numbers, it does say specifically that these reflect the '08 EPA numbers. Concerning the car itself, obv the 08 5AT w/08 EPA can't be directly compared with the 07 4AT w/07 EPA, but I assume the 5MT didn't change gear ratios and nothing with the engine changed AFAIK between 2007 and 2008.Are you sure those numbers from Mazda aren't for the new 08?
+1EPA MPG # does not mean much ...
True MPG depends on how heavy/light on your gas pedal..(wrc)
