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 1 rating for the Aston Martin DBX 727 for 2026. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. 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.
