- Electric-mile share defaults to the EPA utility factor for this vehicle (32% of miles in charge-depleting mode, based on typical daily driving and charging once per day). Adjust it to match your own charging habits.
- MPGe values shown on the EPA label combine electricity and gasoline and cannot be used as ordinary MPG; this estimate prices each energy source separately instead.
Official FuelEconomy.gov estimate: $3,500/year — assumes 15,000 miles/year and EPA price assumptions. The figures above use your inputs instead.
