What it costs to charge a 2026 Kia EV9 GT in Hawaii

A 2026 Kia EV9 GT draws 43 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $19.76 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: 23.3% more per mile than gasoline, because Hawaii's rate and this model's efficiency combine unfavorably.
