Hawaii home charging cost for the 2027 Vinfast VF 9 Plus

A 2027 Vinfast VF 9 Plus draws 49.8 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $22.87 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. This model costs more to charge at home than gas would here: 42.8% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

2027 Vinfast VF 9 Plus: yearly cost in Hawaii

At fueleconomy.gov's default of 15,000 annual miles, the 2027 Vinfast VF 9 Plus costs roughly $3,431 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $1,028 MORE a year than the gas comparison, not less.

What one full charge costs

Covering the 2027 Vinfast VF 9 Plus's EPA-rated 287-mile range takes about 142.9 kWh, which costs about $65.64 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 20,383 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Vinfast VF 9 Plus alone ranks 385 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Where these figures come from

See the methodology guide for exactly which EIA and EPA figures feed 2027 Vinfast VF 9 Plus's cost in Hawaii. This is one of the combinations where charging costs more than gas — the guide to when that happens explains why the arithmetic can go either way.
