Another consideration is pricing. Seat’s brand position would suggest a lower price than the £25k e-Up, further spoiling the business case for the eMii.
Also to be taken into account is the £11k cost of a petrol-engined Mii and the thought of paying twice that for an electric vehicle (EV) version. Given its common underpinnings, it is not surprising that the eMii features an identical specification to the e-Up; this means a 204-cell, 18.7kWh lithium ion battery pack storing energy for a 60kW (79bhp) electric motor and a quoted range of 99 miles.
The battery pack weighs 230kg, and the motor and direct drive transmission increase the kerb weight of a 929kg, 1.0-litre, three-cylinder car by a hefty 300kg to 1229kg.
Nevertheless, the zippy electric powertrain suits a compact city car like the Mii, despite its portly mass. And in Barcelona traffic, the eMii feels like a wieldy machine.
There’s not much feeling to the steering and the body rolls in cornering, but otherwise the eMii steers faithfully and the compact dimensions with a short wheelbase bring a natural agility to the driving experience.
Acceleration is brisk off the mark and the 0-60mph time of 12.4sec makes the eMii the fastest-accelerating model in the range, eclipsing the 75bhp Mii FR by 0.8sec.
There’s no official 0-30mph figure, but at such town speeds the eMii feels quick enough.
Peak torque output of the electric motor is a hefty 154lb ft — the sort of figure a 1.4 turbo petrol engine might push out — but the power delivery characteristic is quite different. The accelerative shove builds evenly and quietly. Powertrain refinement is, of course, outstanding for a small car.
