Which Mii to buy: verdict
Our verdict · Felix Hartmann
- Cheapest to buy: a 1.0 with 44 kW (60 PS), the simplest version.
- Best petrol: the 55 kW (75 PS) engine, with the same 95 Nm but more power at high revs.
- Lowest fuel cost: the Ecofuel, if you have a natural-gas filling station nearby.
- For the city: the 2019-2021 Mii Electric with 36.8 kWh and 260 km of WLTP range.
The SEAT Mii is a city car that SEAT sold from late 2011 to 2021, the Spanish twin of the Volkswagen up! and the Skoda Citigo. All three were built in Bratislava, Slovakia, on the Volkswagen Group's New Small Family platform. Until 2019 the Mii used 1.0-litre three-cylinder petrol and natural-gas engines with 44 to 55 kW; for its last two years it was sold only as the Mii Electric, with 61 kW (83 PS) and 260 km of WLTP range.
In short
- A-segment city car, three- and five-door hatchback, about 3.54 m long, built in Bratislava (2011-2021).
- Petrol engines: 1.0 with 44 kW (60 PS) or 55 kW (75 PS); the Ecofuel natural-gas version had 50 kW (68 PS).
- Mii Electric (2019-2021): 36.8 kWh battery, 61 kW (83 PS), 212 Nm, 260 km WLTP.
- Five Euro NCAP stars in 2011; three stars when the trio was retested in 2019.

SEAT Mii at a glance
| Specification | SEAT Mii |
|---|---|
| Segment | A-segment city car |
| Production | 2011-2021, Volkswagen plant in Bratislava (Slovakia) |
| Platform | Volkswagen Group NSF (New Small Family), front engine, front-wheel drive |
| Body styles | three-door and five-door hatchback (five-door only at the end) |
| Twins | Volkswagen up!, Skoda Citigo |
| Engines | 1.0 MPI petrol, 1.0 Ecofuel (CNG), electric |
| Power range | 44-61 kW (60-83 PS) |
| Predecessor | SEAT Arosa (discontinued in 2004) |
The Mii filled a gap of seven years: SEAT had not offered a car below the Ibiza since the Arosa ended in 2004. It went on sale in Spain in October 2011, the same month production started for Europe; ADAC's German listings begin in May 2012. More SEAT models are on our SEAT brand page.

Generations and versions
The Mii had only one generation, catalogued by ADAC as type AA. Unlike the Skoda Citigo it received no visible facelift; the main change came with the 2020 model year, when SEAT dropped the petrol engines and kept only the electric version.
| Generation | Code | Years | Body styles | Engines | Power (kW / hp) |
|---|---|---|---|---|---|
| Mii (petrol and CNG) | AA, NSF | 2011-2019 | 3-door, 5-door | 1.0 MPI, 1.0 Ecofuel | 44-55 kW (60-75 PS) |
| Mii Electric | AA, NSF | 2019-2021 | 5-door | electric motor, 36.8 kWh | 61 kW (83 PS) |
Special editions included the Mii by Mango, shown at the 2014 Geneva Motor Show and aimed at women buyers, and the Mii by Cosmopolitan of 2016, a collaboration with the magazine.


Engines and transmissions
| Engine | Power | Torque | Fuel | Years (Germany) |
|---|---|---|---|---|
| 1.0 MPI three-cylinder | 44 kW (60 PS) | 95 Nm | petrol | 2012-2018 |
| 1.0 MPI three-cylinder | 55 kW (75 PS) | 95 Nm | petrol | 2012-2018 |
| 1.0 Ecofuel three-cylinder | 50 kW (68 PS) | 90 Nm | natural gas and petrol | 2013-2018 |
| Electric motor | 61 kW (83 PS) | 212 Nm | electric | 2019-2021 |
The years are the periods of the German versions listed by ADAC; ADAC states that petrol Mii models were built until 2019. The petrol engines are the same 999 cc three-cylinders as in the up!, with torque figures from the up!'s data. A five-speed manual gearbox was standard; in some markets the 44 and 55 kW versions could be ordered with a five-speed automated manual. Ecomotive versions added stop-start and brake energy recovery.
The Mii Electric
SEAT showed the Mii Electric in June 2019, opened pre-sales in 14 European countries in mid-September 2019 and started production in Bratislava in the fourth quarter of 2019; the first cars reached dealers in early 2020. It shares its drivetrain with the updated Volkswagen e-up! and the Skoda Citigo-e iV. Compared with the first e-up! of 2013, which had an 18.7 kWh battery and an NEDC range of 160 km, the Mii Electric arrived with almost twice the battery capacity and a range measured on the stricter WLTP cycle.
| Parameter | Mii Electric |
|---|---|
| Motor | 61 kW (83 PS), 212 Nm |
| Battery | 36.8 kWh lithium-ion |
| Range | 260 km (162 miles), WLTP |
| 0-50 km/h | 3.9 s |
| Top speed | 130 km/h (81 mph), limited |
| AC charging | 7.2 kW, about 4 hours |
| DC charging | up to 40 kW (CCS), 80% in about 1 hour |
In Germany SEAT announced a price of EUR 16,300 in September 2019, after subtracting the government and manufacturer incentives. For other small electric cars see our electric cars section.

Dimensions and practicality
| Parameter | Metric | Imperial |
|---|---|---|
| Length | about 3,540 mm | about 139.4 in |
| Width | 1,641 mm | 64.6 in |
| Height | about 1,478 mm | about 58.2 in |
| Wheelbase | 2,420 mm | 95.3 in |
| Fuel tank | 35 l | 9.2 US gal |
The figures are those of the identical Volkswagen up! body; ADAC describes the Mii as just over 3.5 metres long. A boot volume for the Mii is not given in our sources.
Running costs and prices
Official combined consumption of the twin up! with the 44 kW engine was 4.4-4.5 l/100 km (about 52-53 mpg US); the identical Mii engine should be very close, but SEAT's own figures are not in our sources. Our fuel cost calculator converts such figures into a yearly cost. ADAC lists German list prices from EUR 8,990 for the three-door 1.0 with 44 kW in May 2012, from EUR 9,810 for the 55 kW version and from EUR 12,160 for the Ecofuel in 2013.
Trims and equipment
Equipment depended on market and year, from basic versions to the Mango and Cosmopolitan editions with their own colours and trim. Like the up! and Citigo, the Mii could be ordered with an automatic city emergency braking system, which works below 30 km/h; SEAT called it City Safety Assist. It was the first car in its class to offer such a system.

Safety
Euro NCAP awarded the Mii five stars in 2011, with 89% (32 points) for adult occupants, 80% (39 points) for child occupants, 46% (17 points) for pedestrians and 86% (6 points) for safety assist. When Euro NCAP retested the three NSF cars in 2019 under stricter rules, the standard European Mii, up! and Citigo received three stars.
Sales and the end of production
The Mii sold best in 2013, with 28,608 registrations in Europe. That was far below the up!, which found 130,039 European buyers the same year, and also below the Skoda Citigo with 44,851. SEAT ended the petrol versions in 2019 and the whole Mii line-up in 2021.
Reliability and known issues
We have no sourced fault statistics or recall lists for the Mii, so we do not list typical problems here. Because the Mii is mechanically identical to the up! and Citigo, parts are widely available.
