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 4 ratings for the Infiniti QX55 from 2022 to 2025. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. 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.
