Hawaii home charging cost for the 2027 Mercedes-Benz EQS 400 4matic (SUV)

At Hawaii's residential electricity rate of 45.95¢/kWh, a 2027 Mercedes-Benz EQS 400 4matic (SUV) (rated 43 kWh per 100 miles by the EPA) costs $19.76 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: 23.3% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2027 Mercedes-Benz EQS 400 4matic (SUV) costs roughly $2,964 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $561 MORE a year than the gas comparison, not less.

What one full charge costs

Covering the 2027 Mercedes-Benz EQS 400 4matic (SUV)'s EPA-rated 312-mile range takes about 134.2 kWh, which costs about $61.65 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 20,314 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Mercedes-Benz EQS 400 4matic (SUV) alone ranks 324 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

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.
