Hawaii home charging cost for the 2027 MINI Countryman SE ALL4 (18 inch Wheels)

At Hawaii's residential electricity rate of 45.95¢/kWh, a 2027 MINI Countryman SE ALL4 (18 inch Wheels) (rated 34.6 kWh per 100 miles by the EPA) costs $15.88 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. Charging at home costs a little less than gas here: 0.8% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2027 MINI Countryman SE ALL4 (18 inch Wheels) costs roughly $2,383 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $20 a year.

Cost of a full charge

Covering the 2027 MINI Countryman SE ALL4 (18 inch Wheels)'s EPA-rated 216-mile range takes about 74.7 kWh, which costs about $34.31 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 20,090 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The MINI Countryman SE ALL4 (18 inch Wheels) alone ranks 137 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.
