Niro MPG Over the Years
Each bar shows the range of combined MPG across every Niro configuration the EPA rated that year, from the thirstiest version to the most efficient. Hover or tap a year to see the numbers. Electric versions are rated in MPGe, so they're left out of the chart and listed in the table instead.

Why doesn't my Niro match the EPA numbers?
EPA ratings come from standardized lab tests. Your results depend on speed, climate, idling, passengers and cargo, roof racks, tire pressure and upkeep. The ratings are best for comparing one vehicle against another. To track your own numbers, try the MPG calculator.

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 43 ratings for the Kia Niro from 2017 to 2027. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. Electric versions are rated in MPGe, the EPA's miles-per-gallon equivalent, and the table also shows their official range. Plug-in hybrid figures in the table are the gas-only ratings, since those are the ones you can compare with a regular car. 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 or electricity 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.
