Where These Numbers Come From

This page was built by Cedrick Reese from the U.S. EPA fuel economy dataset on fueleconomy.gov, which holds 26 ratings for the Kia K5 from 2021 to 2027. 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.
