Charging a 2027 Vinfast VF 8 Plus at home in Idaho
At Idaho's residential electricity rate of 12.8¢/kWh, a 2027 Vinfast VF 8 Plus (rated 76.1 kWh per 100 miles by the EPA) costs $9.74 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. That works out to 39.2% cheaper per mile than gasoline in Idaho — charging at home is cheaper than gas here.
Annual cost, at 15 thousands miles a year
Idaho owners putting 15,000 annual miles on a 2027 Vinfast VF 8 Plus spend about $1,461 on home electricity, compared to about $2,403 a gas-car equivalent would spend on fuel. Call it about $942 saved annually, at this mileage.
Cost of a full charge
At Idaho's rate, fully covering this 2027 Vinfast VF 8 Plus's 235-mile EPA range costs about $22.89 (178.8 kWh) — the energy the EPA test actually used, not the battery's rated size.

Next step: home charger installation
Everything above is the per-mile and per-year cost once a home charger exists — getting one installed is a separate electrical job whose price depends on your panel and wiring, not the state average used here.
Ask a licensed Idaho electrician to quote the install before this math becomes a real decision.
