Arizona home charging cost for the 2026 Tesla Model S Plaid

A 2026 Tesla Model S Plaid draws 30.6 kWh per 100 miles per the EPA; at Arizona's 15.45¢/kWh residential rate that's $4.73 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 70.5% less than gas per mile, here specifically.
