Why doesn't my Z4 match the EPA numbers?

Where These Numbers Come From
Every figure on this page comes from the U.S. EPA fuel economy dataset on fueleconomy.gov, pulled together by Cedrick Reese. The file lists 94 ratings for the BMW Z4 from 2003 to 2026. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. Ratings from before 2008 use the EPA's revised estimates, which put older vehicles on the same scale as newer ones. When the EPA posts an updated file with new model years or corrected ratings, this page is rebuilt from it. The cost calculator uses the gas price you enter rather than a national average, so the result fits where you live.
