Washington home charging cost for the 2026 Honda Prologue FWD

In Washington, home electricity runs 14.35¢/kWh — put a 2026 Honda Prologue FWD's EPA-rated 32.5 kWh/100mi against that and 100 miles costs $4.67, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 70.8% less than gas per mile, here specifically.
