Lower mileage figures resulted. The aim of the revised test procedures was to give mileage estimates that better reflected numbers that average drivers were achieving. The Yaris didn't change when its posted mileage estimates went down. Just the test.

OHHHHH, I was under the impression that the old EPA tests were just numbers plugged in to some machine/computer or something. (You can see I'm ignorant to a lot of this stuff.) I knew the car didn't change and that it was just the tests changing, but I thought the new EPA tests were actual tests as opposed to calculations. My bad

The same goes for the e10 mixture which I also don't know much about.

Regardless, removing that misinformed point from my previous statement, I think I'm doing fine with my Yaris in the FE department but it is cool that another FE car is being added to the fleet. I just hope it is as good as we all hope.

What you're probably thinking of is that the fuel consumption is actually calculated from the measured output of fuel products such as carbon dioxide. Seems backward, but if anyone's seen the clever ways some of those NASCAR mechanics have hidden extra fuel in cars they'll understand why it's done that way.
