The Mazda MX-30 is rated 92 MPGe (98 city, 85 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 36.6 kWh per 100 miles, so 12,000 miles a year costs about $747 at $0.17 a kWh. The EPA's own annual figure for it is $850.
Every Mazda MX-30 version, compared
The Mazda MX-30 was rated in a single specification, so its consumption does not vary by version — only by model year. Yearly cost assumes 12,000 miles at $0.17 a kilowatt-hour.
| Version | Combined MPGe | City / Highway | Years | Charging per year |
|---|---|---|---|---|
| Electric | 98 / 85 | 2022–2023 | $747 |
What that actually costs
MPGe is an abstraction; the electricity bill is not. At 12,000 miles a year the Mazda MX-30 draws about 4392 kWh, which at $0.17 comes to the figures below.
| Measure | Value |
|---|---|
| Energy use | 36.6 kWh per 100 miles |
| Cost per mile | $0.062 |
| Charging per year | $747 |
| Charging over five years | $3,735 |
| Against other Electric cars | +$66 a year |
| EPA's own estimate | $850 a year |
City or highway — who is this car for
The Mazda MX-30 is one of the cars that does better in town than out of it — 98 in the city against 85 on the highway. That is $60 a year in favour of the commuter stuck in traffic, and it usually means a hybrid drivetrain recovering energy every time you brake.
| Measure | Value | Reading |
|---|---|---|
| City | 98 MPGe | $702 a year if you only drive in town |
| Highway | 85 MPGe | $808 a year if you mostly commute |
| Gap | -13 MPGe (-13%) | Reversed — it does better in town than on the open road |
How the MX-30 changed over the years
Combined figure across the 2 model years the MX-30 was rated in, all of them at 92 MPGe.
| Model year | Combined MPGe | City / Highway | Versions offered | Charging per year |
|---|---|---|---|---|
| 2023 | 98 / 85 | 1 | $747 | |
| 2022 | 98 / 85 | 1 | $747 |

How we count
This page rests on 2 EPA ratings of the Mazda MX-30 — 1 engine across 2022–2023. The mileage is EPA's laboratory figure, unchanged; the yearly bill is ours, at 12,000 miles and $0.17 a kilowatt-hour, against EPA's own estimate of $850. Full method.
Frequently asked questions
What is the Mazda MX-30 rated at?
92 MPGe combined on average — 98 in the city and 85 on the highway, per EPA ratings across 2022–2023. MPGe is distance covered on 33.7 kWh, the energy in a gallon of petrol — the car itself takes none.
How much does a Mazda MX-30 cost to charge per year?
About $747 at 12,000 miles and $0.17 a kilowatt-hour — roughly $3,735 over five years, or 0.062 dollars a mile.
Which MX-30 version is the most efficient?
The Electric at 92 MPGe.
Is the MX-30 efficient compared with similar cars?
Against other Electric cars it sits below the average of 101 MPGe, computed across 426 ratings.
Are these real-world MX-30 figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Mazda MX-30 is $850 against the $747 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.
