Charging a 2026 Maserati Grecale Folgore (20 inch Wheels) at home in Hawaii

At Hawaii's residential electricity rate of 45.95¢/kWh, a 2026 Maserati Grecale Folgore (20 inch Wheels) (rated 41.7 kWh per 100 miles by the EPA) costs $19.17 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. Here the math runs the other way: 19.7% more per mile than gasoline, because Hawaii's rate and this model's efficiency combine unfavorably.

What a year of driving costs

Hawaii owners putting 15,000 annual miles on a 2026 Maserati Grecale Folgore (20 inch Wheels) spend about $2,876 on home electricity, compared to about $2,403 a gas-car equivalent would spend on fuel. At this mileage, that's roughly $473 a year worse than the gas comparison.

Cost of a full charge

Before you install a home charger in Hawaii

Everything above is the per-mile and per-year cost once a home charger exists — getting one installed is a separate electrical job whose price depends on your panel and wiring, not the state average used here.

Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.

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.
