2026 Toyota bZ LIMITED (energy capacity 191 Ah): home charging cost in Arizona

At Arizona's residential electricity rate of 15.45¢/kWh, a 2026 Toyota bZ LIMITED (energy capacity 191 Ah) (rated 26.9 kWh per 100 miles by the EPA) costs $4.15 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home costs a fraction of what gas would here: 74.1% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Toyota bZ LIMITED (energy capacity 191 Ah) charged at home in Arizona costs about $623/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,780 a year.
