Charging a 2026 Mercedes-Benz AMG EQE 4matic Plus at home in Hawaii

A 2026 Mercedes-Benz AMG EQE 4matic Plus draws 48 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $22.06 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Here the math runs the other way: 37.7% more per mile than gasoline, because Hawaii's rate and this model's efficiency combine unfavorably.

Annual cost, at 15 thousands miles a year

Hawaii owners putting 15,000 annual miles on a 2026 Mercedes-Benz AMG EQE 4matic Plus spend about $3,308 on home electricity, compared to about $2,403 a gas-car equivalent would spend on fuel. At this mileage, that's roughly $905 a year worse than the gas comparison.

Cost of a full charge

At Hawaii's rate, fully covering this 2026 Mercedes-Benz AMG EQE 4matic Plus's 220-mile EPA range costs about $48.52 (105.6 kWh) — the energy the EPA test actually used, not the battery's rated size.

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.

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.
