BMW forced to lower 2012 3 Series automatic fuel economy to 33 mpg

From AB

All manufacturers are responsible for testing and submitting fuel
economy figures each year to the EPA (based on physical tests
following the EPA test cycle on a dynamometer). Occasionally, the EPA
will validate the figures that we provide. When this happens, there
are sometimes small changes in the published EPA fuel economy figures
(usually 1 mpg up or down).

The EPA recently tested the 2012 328i Automatic and obtained a highway
mileage result that was 3m pg lower (33mpg versus 36mpg) than the BMW
test result. We are very surprised by this result and are currently
working to determine how this is possible. The new rating seems
abnormally low in relation to the other models in the BMW range and by
the real-world fuel economy that we are seeing from this model.

Unfortunately, there is no provision in the EPA rules for a re-test
this year. Therefore regardless of the results of our investigation,
the new rating will stand for this model year.
