New Seat Mii Electric specifications, range and prices

Seat has launched an electric version of its Mii city car, capable of 161 miles per charge. Could this small car be the next big thing?

The new Seat Mii Electric is now available to order. It's the first electric car from Seat, sharing the majority of its technology and general design with the closely related VW e-Up. With an electric range of 161 miles, and a starting price of £19,300 - after the UK government’s £3,500 plug-in car grant - the Mii Electric enters a growing all-electric city car market with some competitive numbers behind it.

But does this tiny car offer enough to warrant that high price - which is well over twice as much as you'd pay for a 2019 petrol Seat Mii that has covered barely 100 miles? Keep reading to find out more.

Being a compact city car, the Mii Electric has limited space for a battery, which ultimately limits its maximum range. That said, if you're driving your city car where it belongs - in the city - you're unlikely to cover more than 100 miles in one trip, so we'd suggest that being able to cover up to 161 miles per charge is more than enough, it's certainly more than many alternatives in this sector.

There are positives for an electric car of this size though. The Seat Mii Electric targets those who predominantly drive around town, which makes a lot of sense. Urban drivers tend to do lots of short, stop-start driving which is perfect for an electric car, as it provides plenty of opportunities to top up a battery via what's known as 'regenerative braking', with the car reclaiming some of the energy that would otherwise be wasted when braking.

Quick facts

  • Seat’s first all-electric vehicle
  • Claimed range of 161 miles
  • Prices starting at £19,300
  • Plenty of standard equipment
  • Can charge from zero to 80% in one hour
  • Five exterior colours to choose from

With governments across the globe becoming increasingly worried about the health implications of air pollution due to emissions from burning fossil fuels - especially in highly populated built-up areas - there has been a growing shift towards electric cars. This is due to electric cars producing no tailpipe emissions, though their environmental impact depends upon how the energy used to charge them is generated.

Many governments are even bringing in penalties for driving conventionally powered cars in major cities. Cars like the Mii Electric allow drivers to stay mobile, without having to worry about taxes placed on more traditional cars.


Seat Mii Electric models and trims

To keep things simple, Seat is only offering one version of the Mii Electric, so there's no need to worry about picking the right one for you. It doesn’t have a fancy name either; it is simply called the Mii Electric.

Much like most other electric cars, standard equipment is generous – in fact, you won’t find any optional extras either, as all the equipment available is included. Standard kit includes parking sensors, air-conditioning, cruise control, automatic wipers, lane keep assist, traffic sign recognition, Bluetooth, DAB radio, a five-inch media display, heated seats, a leather steering wheel and 16-inch alloy wheels.

Seat Mii Electric prices and delivery dates

Prices for the Seat Mii Electric start and finish at £19,300 on account of there being only one model on offer and no optional extras. This price includes the £3,500 government grant available to UK electric car buyers. Furthermore, order books are open now with first deliveries expected during the first quarter of 2020.

As a deal sweetener, Seat has pledged to provide the first 300 retail buyers with a home wall box charger, plus three years' of servicing and roadside assistance free of charge.

As for company car drivers the Seat Mii Electric’s P11D value is £22,745, which initially seems very high for a small car. However, company car tax rates are about to change to favour electric car drivers – so company car drivers who opt for all-electric vehicles will pay zero BIK tax during the 2020/2021 tax year and just 1% the year after.

Seat Mii Electric range and charge times

Official range is claimed to be 161 miles under that latest, more realistic economy tests. As always, it is worth remembering that typical drivers are likely to achieve less than this in the real world – this will be especially noticeable while driving on cold days. That's because cold temperatures reduce how much charge the batteries hold.

Every Seat Mii Electric comes with a 36.8kWh battery pack, which when connected to a 40kW charging station - an output this high is most common with non-domestic charging locations - the Mii Electric can go from 0-80% charge in one hour. On the other hand, using a 7.2kW home charger would take around four hours to charge the car from 0-80%.

When it comes to the cost of charging, there are a number of factors which could affect the bottom line, such as whether you are using a commercial charge point or a domestic one. As most electric car owners will predominantly charge using the latter, that is what the following information is based on.

Assuming an electricity price of 13.8p per kWh, fully charging a Seat Mii Electric will cost £5.08. For reference, this is similar money to charging a VW e-Up or Hyundai Ioniq Electric. Find out which electric cars are the cheapest to charge here.

Seat Mii Electric rivals and alternatives

Arguably the biggest rival for Seat’s Mii Electric comes from the closely related Volkswagen e-Up city car. For those unaware VW and Seat are part of the same company, so much of the technology under the skin is shared between the two cars.

VW will shortly start rolling out an updated e-Up which is expected to cost roughly £19,000 and offer a range of around 160 miles. Sound familiar? Volkswagen has yet to confirm full details of specifications and trims but based on the information currently available, the biggest deciding factor for which petite electric car to buy is likely to be the badge.

Outside of VW’s family of car brands, there is the Smart ForTwo, though this only has two seats and a very limited range of around 70 miles. All fully electric Smart ForTwos come well equipped and well made however the limited range and number of seats limit its appeal. That said, Smart offers the EQ ForTwo with a foldable roof – which neither the Seat nor VW are available with.

Those aren't the only small electric car rivals either. Order books recently opened for the new and hotly anticipated Honda e all-electric e model. Prices sit around £27,000 (after the plug-in car grant mentioned elsewhere) and range is claimed to be around 136 miles on a single charge, however, so this is a pricier prospect.

If you are happy to drive a slightly larger car (and pay some extra money) cars such as the Renault Zoe (a new version of which will be going on sale in 2020) and BMW i3 are potential options as well.

Consider the vast number of used Zoes and i3s available, however, and you can get a relatively recent model from around £8,000 in the case of the Renault and £18,000 for the BMW, making these even more affordable.

Seat Mii Electric economy and performance

Powering each and every Seat Mii Electric is an 82hp electric motor which produces a substantial 212Nm of torque – torque is largely responsible for how fast a car accelerates, so expect the car to feel faster than the figures suggest.

Seat has said the Mii Electric will sprint from a standstill to 31mph in 3.9 seconds and hit 62mph in 12.3 seconds - both of which are relatively slow compared with most new cars - and that the top speed is 81mph.

As for economy, Seat is again yet to announce official consumption figures. For a refresher on how economy figures work for electric cars, take a read of our dedicated electric car economy article.

Seat Mii Electric interior

While Seat hasn’t designed a completely new interior for the Mii Electric, there are a handful of standout features. These include heated cloth sports seats - with height adjustment for the driver's seat - a leather gear knob and handbrake lever, plus a smattering of chrome inserts around the cabin.

There is no massive touchscreen information and media display in the Mii Electric’s cabin. Instead, Seat provides a simpler five-inch display and universal smartphone cradle – the idea being that drivers can connect their phones to the car for functions such as navigation and music streaming.

Seat Mii Electric exterior

To set all-electric Miis apart from standard petrol models, Seat has dotted some “Mii Electric” badges around the exterior and provided 16-inch alloy wheels painted in grey as standard. LED daytime running lights, heated door mirrors and tinted rear windows are standard also.

Buyers get the choice of five metallic colours - black, white, red, blue and silver – all of which are free to choose. Each colour is available with a black contrasting roof, too, except for black which is only available with a black matching roof. Opting for a contrasting roof is again completely free.

Seat Mii Electric technology

On top of being Seat’s first all-electric production car, the Mii Electric is also the Spanish brand’s first vehicle to come with Seat Connect functionality. This revolves around a smartphone app (Seat Connect) which brings control and analytics of key car information via the driver's smartphone.

This includes pre-heating or cooling of the cabin before a journey - typically using power from the mains when plugged in to heat or cool the cabin, rather than draining the battery - checking where a vehicle is parked and even looking at information such as remaining range.

There is another app available to owners as well – the Drive Mii app. This works with Seat’s universal smartphone cradle mentioned above and brings TomTom-powered navigation plus an 'eco trainer' feature which helps drivers maximise the range of their vehicle.

Seat Mii Electric dimensions

Being a city car, the Seat Mii Electric is modest in its proportions. It measures in at 3,557mm long, 1,645mm wide and 1,478mm high. As a result, it should be very easy to park and for winding through tight city streets.

Boot capacity is identical to petrol models at 251 litres - which is a substantial amount for a car this small - and with the rear seats (which split 60:40) folded down this raises to 923 litres.

Seat Mii Electric review

There are a number of make or break areas the Seat Mii Electric needs to excel in for it to be a decent city car purchase. For starters, how accurate are the range and charge time claims? Then there is how well Seat’s universal smartphone cradle and supporting apps work. Executed well, using a smartphone instead of a touchscreen in a city car seems like a smart move, but the question remains as to whether Seat has integrated this well.

One other major area to assess is how the Mii Electric drives in town, on A roads and on the motorway, as despite being a city car there will more than likely be a time when drivers will venture outside the city limits.
