EV vs gas car — annual fuel cost

| Annual mileage | BMW iX xDrive50 (home) | 28-mpg gas | 40-mpg hybrid | EV savings vs gas |
|---|---|---|---|---|
| 6,000 mi | $915 | $1039 | $728 | $125 |
| 10,000 mi | $1524 | $1732 | $1213 | $208 |
| 12,000 mi | $1829 | $2079 | $1455 | $249 |

Home vs public DC fast charging
Home charging is the default cost optimization. Public DC fast charging in Hawaii runs about 1.4× the home rate. For 12,000 miles/yr entirely on DC fast, annual fuel cost would be $2575 vs $1829 at home — a $746 penalty. Apartment dwellers and road-trippers should price this in; daily commuters with home Level 2 can usually ignore public chargers.
DC fast rate is a network average (Electrify America + EVgo + Tesla Supercharger + ChargePoint). Real prices vary by location, time of day, and membership tier.
EV incentives in Hawaii
Hawaii does not currently run a state-level EV purchase rebate. Federal Section 30D credit of $7,500 still applies for qualifying vehicles (US-assembled with sourced battery components, MSRP cap, household income cap). Check the EV tax credit eligibility list for your vehicle. Some utilities offer charger installation rebates — check with your local utility.

- Does winter weather affect charging cost in Hawaii?
- Yes — cold weather can reduce EV efficiency by 15-30% (battery + heater draw). The numbers above use EPA combined ratings; budget +20% for sustained sub-freezing temps. Hot-state drivers see less impact, but AC use in extreme heat also reduces range.
