Why doesn't my Uncharted match the EPA numbers?
EPA ratings come from standardized tests so every EV is measured the same way. Cold weather, heater and AC use, highway speed, tire pressure and cargo all change how far a Uncharted goes on a charge. The ratings are best for comparing one model against another.

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 6 ratings for the Subaru Uncharted from 2026 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. When the EPA posts an updated file with new model years or corrected ratings, this page is rebuilt from it. The cost calculator uses your electricity rate 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.
