Where These Numbers Come From

Cedrick Reese built this page from the EPA fuel economy file published on fueleconomy.gov. It has 7 ratings for the RS 6 from 2003 to 2026, and every one of them is shown in the table. 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.

Ratings on this page come from the EPA file downloaded on October 1, 2026.
