2027 Mercedes-Benz EQS 400 4matic (SUV), HI Charging Cost

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.
