2026 Porsche Taycan GTS Sport Turismo: home charging cost in Hawaii

A 2026 Porsche Taycan GTS Sport Turismo draws 41 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $18.86 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. This model costs more to charge at home than gas would here: 17.7% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Porsche Taycan GTS Sport Turismo charged at home in Hawaii costs about $2,829/year in electricity, against about $2,403/year for the gas-car comparison. That's about $426 MORE a year than the gas comparison, not less.

Where this ranks

This combination ranks 20,273 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Taycan GTS Sport Turismo alone ranks 287 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.
