The Hyundai Ioniq 6 is rated 138.3 MPGe (152.3 city, 124.7 highway) — that is not petrol economy but the distance it covers on 33.7 kWh, the energy held in one gallon. Drawn from a socket it needs 24.4 kWh per 100 miles, so 12,000 miles a year costs about $498 at $0.17 a kWh. The EPA's own annual figure for it is $550.

| Measure | Value | Reading |
|---|---|---|
| City | 152.3 MPGe | $451 a year if you only drive in town |
| Highway | 124.7 MPGe | $551 a year if you mostly commute |
| Gap | -27.6 MPGe (-18%) | Reversed — it does better in town than on the open road |

Are these real-world Ioniq 6 figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Hyundai Ioniq 6 is $550 against the $498 we compute at 12,000 miles. Expect a little worse in practice: the spread between the city and highway figures is smaller than the spread between two drivers of the same one.
