The Smart EQ Fortwo is rated 108 MPGe (124 city, 94 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 31.2 kWh per 100 miles, so 12,000 miles a year costs about $636 at $0.17 a kWh. The EPA's own annual figure for it is $700.

City or highway — who is this car for
The Smart EQ Fortwo is one of the cars that does better in town than out of it — 124 in the city against 94 on the highway. That is $99 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 | 124 MPGe | $555 a year if you only drive in town |
| Highway | 94 MPGe | $732 a year if you mostly commute |
| Gap | -30 MPGe (-24%) | Reversed — it does better in town than on the open road |

Frequently asked questions
What is the Smart EQ Fortwo rated at?
108 MPGe combined on average — 124 in the city and 94 on the highway, per EPA ratings across 2019–2019. MPGe is distance covered on 33.7 kWh, the energy in a gallon of petrol — the car itself takes none.
How much does a Smart EQ Fortwo cost to charge per year?
About $636 at 12,000 miles and $0.17 a kilowatt-hour — roughly $3,180 over five years, or 0.053 dollars a mile.
Which EQ Fortwo version is the most efficient?
The Electric at 108 MPGe.
Is the EQ Fortwo 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 EQ Fortwo figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Smart EQ Fortwo is $700 against the $636 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.
