54.5 "CAFE" MPG is actually 36-40 "real world" MPG

Please see previous post about CAFE adjustment factor. It's not 55 mpg, it will be more like low-mid 40's on the window sticker.

EDIT: tracking down the "real" (window sticker) equivalent of 54.5 CAFE mpg, this credible source says it will in fact be closer to 36 mpg.

EDIT 2:

Because CAFE compliance tests are out of date and overinflate fuel
economy, the average on-road fuel economy of cars and light trucks is expected to be 36-40 mpg by 2025, up from 21 mpg today. See http://www.ucsusa.org/assets/documen...to-On-Road.pdf for more information.
