Snapshot by model year
Each EPA configuration counts once. Medians below are not weighted by sales, driving distance or vehicle age. Gasoline, hybrid and diesel records share the liquid-fuel column; battery EVs use a separate unit. A year-to-year change can reflect which models are included, not a change in fleet efficiency.
