Where These Numbers Come From
Cedrick Reese built this page from the EPA fuel economy file published on fueleconomy.gov. It has 68 ratings for the Q50 from 2014 to 2024, 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. 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.
