Why doesn't my RZ 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 RZ 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 16 ratings for the Lexus RZ from 2023 to 2026. 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.
