Summary
The SEAT Mii Electric was a small city car-class hatchback, which (as its name suggests) was powered by an electric motor rather than a petrol engine. It was launched in the UK in late 2019 with the first cars arriving in early 2020.
The Mii Electric was an electric version of the original petrol SEAT Mii, which had been around since 2012 and was taken off sale in early 2019. So although it may have been launched in 2019, it was far from an all-new model. The Mii Electric was basically the same vehicle as the Volkswagen e-Up and Skoda Citigo e iV, with only minor cosmetic and trim differences across all three vehicles.
As the Mii Electric was only launched in the UK in early 2020, we only have 14 reviews analysed. Interestingly, the little SEAT scores a few points better than the Volkswagen e-Up on which it’s based.
Based on the reviews analysed, the SEAT Mii Electric was praised for being one of the more affordable options in the electric car market. However, it’s was not really suited outside an urban environment, and it’s sub-par three-star Euro NCAP safety rating was off the pace of newer rivals.

“A welcome, affordable addition to the EV sphere that offers capability and comfort but lacks verve.”

“This is a thoroughly successful evolution of the city car, and one that – together with its Skoda and Volkswagen stable mates – seems likely to set the pattern for the future of a class that suits electrification probably better than any other.”

“The SEAT Mii Electric shares much with the Volkswagen e-Up! but offers buyers some extra style and better value.”

“The SEAT Mii Electric is just as small as the standard Mii, but it’s even easier to drive in cities thanks to its perky electric motor. Alternatives can travel further on a single charge, though.”

“The SEAT Mii Electric makes a persuasive case for the city-dwelling market, who want affordable, fun motoring while being mindful of the environment. The move to an electric powertrain is perfect for this little city car, and if you can live with the range it is a great choice.”

“SEAT’s take on the VW Up & Skoda Citigo is a damn good EV. Though of the three, it’s not the one we’d have.”

What Car?
Score: 8 / 10
“If you are after electric motoring in a comparatively affordable, bitesize package, the SEAT Mii Electric has plenty going for it. The main draw is its price, and while its electric range may not be as long as some other electric cars can manage, it should still be plenty for many potential buyers.”

The petrol SEAT Mii was originally awarded a five-star rating by Euro NCAP way back in 2011*. However, this rating expired in 2018 when the car no longer met the relevant criteria for a five-star vehicle. The electric version was tested by Euro NCAP in 2019*, when it was awarded the three-star rating shown above.
*the actual vehicles tested in each case were the Volkswagen Up! in 2011 and the Volkswagen e-Up! in 2019. The Volkswagen is structurally identical to the SEAT Mii and the Skoda Citigo, so the same rating applies to all three brands.
Eco rating
Independent economy and emissions ratings from Green NCAP
No eco rating
The SEAT Mii Electric was not lab tested by Green NCAP during its production life
The Green NCAP programme measures exhaust pollution (which is zero for an electric car) and energy efficiency. Electric cars are much more energy-efficient than combustion cars, so the Mii Electric would have been likely to score very highly in Green NCAP testing if it had ever taken place.

The SEAT Mii Electric is a very affordable car to own and run, according to whole-life cost numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.
We don’t have five-year servicing cost data on the Mii due to its age, but its electrical efficiency (the EV equivalent of fuel economy) and insurance group are very competitive. The battery is quite small, however, so the driving range is going to be less than a lot of other electric cars.

The SEAT Mii Electric is essentially a re-badged version of the Volkswagen e-Up. Most of the other cars listed above are all a bit larger and/or more expensive, and are classed as superminis rather than city cars – although, realisitically any small electric car is best suited to city and urban driving.
