2026 Porsche Taycan GTS: home charging cost in Montana

In Montana, home electricity runs 13.77¢/kWh — put a 2026 Porsche Taycan GTS's EPA-rated 39 kWh/100mi against that and 100 miles costs $5.37, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 66.5% less than gas per mile, here specifically.
