What it costs to charge a 2026 Rivian R1T Tri Max (22in) in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Rivian R1T Tri Max (22in)'s EPA-rated 44.6 kWh/100mi against that and 100 miles costs $20.48, versus $16.02 for a gas car averaging 25.5 mpg. Here the math runs the other way: 27.8% more per mile than gasoline, because Hawaii's rate and this model's efficiency combine unfavorably.
