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 21 ratings for the Audi S6 from 1995 to 2025. 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. The page is rebuilt whenever the EPA publishes an updated file, which picks up new model years and any rating corrections. The cost calculator uses the gas price you enter rather than a national average, so the result fits where you live.
