Yes, the same EPA tests are used for the CAFE standards and the
figures used on the Monroney label.

An average of the raw city and highway MPG data is used for the CAFE
standards.

However, for the Monroney label (window sticker and fueleconomy.gov
listing) since the mid-1980s through 2007, the EPA test results are
discounted (lowered) by a multiplier, down 10% for city and 22% for
highway. Yes, this was to make them more "realistic" to the early
1980s American driver. The numbers you see listed on the Monroney
label is not the actual results of the EPA tests, but this lowered
number based on the tests.
