Hawaii home charging cost for the 2026 Lucid Gravity Dream w/21F22R wheels (3R)
A 2026 Lucid Gravity Dream w/21F22R wheels (3R) draws 37.6 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $17.3 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: 8% 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
At fueleconomy.gov's default of 15,000 annual miles, the 2026 Lucid Gravity Dream w/21F22R wheels (3R) costs roughly $2,594 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $191 MORE a year than the gas comparison, not less.
Filling up the 2026 Lucid Gravity Dream w/21F22R wheels (3R), in dollars
Covering the 2026 Lucid Gravity Dream w/21F22R wheels (3R)'s EPA-rated 378-mile range takes about 142.3 kWh, which costs about $65.38 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 20,186 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Lucid Gravity Dream w/21F22R wheels (3R) alone ranks 207 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
The methodology guide names the exact EIA and EPA tables behind this page's numbers. 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.
