EPA tests produce one number. It was soon discovered that the number was unrealistic for "real world" comparison. That number is then adjusted down by a factor, and the result is posted on the window sticker.
Corporate Average Fuel Economy is still calculated by the old unadjusted numbers. The 54 mpg goal being discussed is CAFE.

My Fit got 35/46 mpg on the test. That is adjusted down to its actual 27/33 rating.
