Except that doesn't make any sense as they don't actually test the cars on the road right? Basically run it on a dyno and add numbers into a computer program. I have always wondered why they don't list different mpg for different available gear ratios. What do they get to use the best available even if it's not want is actually installed in that car/truck. This is more common on trucks were ranges from 3.2-4.1:1 are possible yet the epa rating is the same.
