Hawaii home charging cost for the 2026 Lexus RZ 550e AWD
In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Lexus RZ 550e AWD's EPA-rated 35.3 kWh/100mi against that and 100 miles costs $16.23, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 1.3% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.
What a year of driving costs
At fueleconomy.gov's default of 15,000 annual miles, the 2026 Lexus RZ 550e AWD costs roughly $2,434 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $31 MORE a year than the gas comparison, not less.
Filling up the 2026 Lexus RZ 550e AWD, in dollars
Covering the 2026 Lexus RZ 550e AWD's EPA-rated 229-mile range takes about 80.9 kWh, which costs about $37.16 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
How this compares nationally
This combination ranks 20,117 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Lexus RZ 550e AWD alone ranks 157 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.
Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.
Where these figures come from
See the methodology guide for exactly which EIA and EPA figures feed 2026 Lexus RZ 550e AWD'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.
