Solterra MPGe Questions
Which Solterra is the most efficient?
The 2026 and 2027 Solterra AWD has the top EPA rating at 120 MPGe combined (131 city, 109 highway).
What's the range of the 2026 Solterra?
The most efficient 2026 Solterra AWD is rated at 120 MPGe combined, which works out to 28 kWh per 100 miles. Its EPA range is 288 miles. Range across 2026 versions runs from 278 to 288 miles.
What does MPGe mean?
MPGe stands for miles per gallon equivalent. The EPA counts 33.7 kWh of electricity as one gallon of gasoline, so a rating of 120 MPGe means the 2026 Solterra AWD covers 120 miles on 33.7 kWh. kWh per 100 miles is the easier number for working out charging costs.
Why doesn't my Solterra 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 Solterra 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 10 ratings for the Subaru Solterra from 2023 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. The page is rebuilt whenever the EPA publishes an updated file, which picks up new model years and any rating corrections. 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.
