Hawaii home charging cost for the 2026 Porsche Taycan 4 Performance Battery

A 2026 Porsche Taycan 4 Performance Battery draws 38.6 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $17.72 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: 10.6% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Filling up the 2026 Porsche Taycan 4 Performance Battery, in dollars

Covering the 2026 Porsche Taycan 4 Performance Battery's EPA-rated 251-mile range takes about 96.8 kWh, which costs about $44.49 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 20,208 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Taycan 4 Performance Battery alone ranks 229 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

See the methodology guide for exactly which EIA and EPA figures feed 2026 Porsche Taycan 4 Performance Battery's cost in Hawaii. 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.
