Where These Numbers Come From

Cedrick Reese built this page from the EPA fuel economy file published on fueleconomy.gov. It has 16 ratings for the Legacy from 2018 to 2025, 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.
