The Mitsubishi i-MiEV is rated 112 MPGe (125 city, 99.6 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 30.1 kWh per 100 miles, so 12,000 miles a year costs about $614 at $0.17 a kWh. The EPA's own annual figure for it is $700.
Every Mitsubishi i-MiEV version, compared
Efficiency on the Mitsubishi i-MiEV ranges from 112 down to 112 depending on the battery and drive fitted — a spread of $0 a year across 2 versions of the same car. Picking the right one often saves more current than picking a different car altogether. Yearly cost assumes 12,000 miles at $0.17 a kilowatt-hour.
| Version | Combined MPGe | City / Highway | Years | Charging per year |
|---|---|---|---|---|
| Electric | 124.8 / 99.8 | 2012–2017 | $614 | |
| 0L | 126 / 99 | 2016–2016 | $614 |
What that actually costs
MPGe is an abstraction; the electricity bill is not. At 12,000 miles a year the Mitsubishi i-MiEV draws about 3612 kWh, which at $0.17 comes to the figures below.
| Measure | Value |
|---|---|
| Energy use | 30.1 kWh per 100 miles |
| Cost per mile | $0.051 |
| Charging per year | $614 |
| Charging over five years | $3,070 |
| Against other Electric cars | −$67 a year |
| EPA's own estimate | $700 a year |
City or highway — who is this car for
The Mitsubishi i-MiEV is one of the cars that does better in town than out of it — 125 in the city against 99.6 on the highway. That is $79 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 | 125 MPGe | $551 a year if you only drive in town |
| Highway | 99.6 MPGe | $690 a year if you mostly commute |
| Gap | -25.4 MPGe (-20%) | Reversed — it does better in town than on the open road |
How the i-MiEV changed over the years
Combined figure across the 5 model years the i-MiEV was rated in, all of them at 112 MPGe. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
| Model year | Combined MPGe | City / Highway | Versions offered | Charging per year |
|---|---|---|---|---|
| 2017 | 121 / 102 | 1 | $614 | |
| 2016 | 126 / 99 | 1 | $614 | |
| 2014 | 126 / 99 | 1 | $614 | |
| 2013 | 126 / 99 | 1 | $614 | |
| 2012 | 126 / 99 | 1 | $614 |

How we count
This page rests on 5 EPA ratings of the Mitsubishi i-MiEV — 2 engines across 2012–2017. 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 $700. Full method.
Frequently asked questions
What is the Mitsubishi i-MiEV rated at?
112 MPGe combined on average — 125 in the city and 99.6 on the highway, per EPA ratings across 2012–2017. MPGe is distance covered on 33.7 kWh, the energy in a gallon of petrol — the car itself takes none.
How much does a Mitsubishi i-MiEV cost to charge per year?
About $614 at 12,000 miles and $0.17 a kilowatt-hour — roughly $3,070 over five years, or 0.051 dollars a mile.
Which i-MiEV version is the most efficient?
The Electric at 112 MPGe, against 112 for the 0L — a difference of about $0 a year.
Is the i-MiEV efficient compared with similar cars?
Against other Electric cars it sits above the average of 101 MPGe, computed across 426 ratings.
Are these real-world i-MiEV figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Mitsubishi i-MiEV is $700 against the $614 we compute at 12,000 miles. Expect a little worse in practice: the spread between the 112 and 112 mpg versions of this car is smaller than the spread between two drivers of the same one.
