Charging a 2027 Vinfast VF 9 Plus at home in Maine

In Maine, home electricity runs 29.67¢/kWh — put a 2027 Vinfast VF 9 Plus's EPA-rated 49.8 kWh/100mi against that and 100 miles costs $14.77, versus $16.02 for a gas car averaging 25.5 mpg. That works out to 7.8% cheaper per mile than gasoline in Maine — charging at home costs a little less than gas here.

What a year of driving costs

Cost of a full charge
