Hawaii home charging cost for the 2026 Polestar 4 Long Range Dual Motor
At Hawaii's residential electricity rate of 45.95¢/kWh, a 2026 Polestar 4 Long Range Dual Motor (rated 40 kWh per 100 miles by the EPA) costs $18.38 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. This model costs more to charge at home than gas would here: 14.7% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.
Annual cost, at 15 thousands miles a year
At fueleconomy.gov's default of 15,000 annual miles, the 2026 Polestar 4 Long Range Dual Motor costs roughly $2,757 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $354 MORE a year than the gas comparison, not less.
What one full charge costs
Covering the 2026 Polestar 4 Long Range Dual Motor's EPA-rated 280-mile range takes about 112 kWh, which costs about $51.46 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
Where this ranks
This combination ranks 20,255 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Polestar 4 Long Range Dual Motor alone ranks 270 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.
Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.
Where these figures come from
Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. 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.
