Seat has announced that UK pricing for the Mii Electric, its first zero-emissions model, will begin at £19,300, making it one of the cheapest mainstream EVs available in the UK.
Seat is also offering the first 300 buyers fitment of a wall-mounted home charger, a three-pin home-charging cable, three years' servicing and roadside assistance free of charge.
The supermini's sub-£20,000 price tag is lower than that of its Vauxhall Corsa-e, Peugeot e-208, Mini Electric and Honda E rivals. The new Renault Zoe is available from £18,670 under the firm's battery leasing scheme, but monthly costs have yet to be revealed.
As part of Seat's 'easyMOVE' range simplification strategy, only one trim is available from launch.
Standard equipment includes metallic paint, lane assist, fast-charging capabilities, 16in alloy wheels, air conditioning and automatic windscreen wipers.
Owners can also make use of an associated smartphone app, which allows the climate control, lights and locks to be activated remotely, and gives information on journey times and the car's location.
With an 82bhp electric motor mated to a single-speed transmission, the Mii Electric produces 156lb ft torque, enabling it to accelerate from 0-31mph in 3.9sec and on to a limited top speed of 81mph.
A 36.8kWh battery pack gives a WLTP-certified range of 162 miles. That's two miles fewer than the 164 offered by the Citigo-e iV but 79 more than the ageing Volkswagen e-Up.
Styling changes over the outgoing Mii are subtle, limited to 16in alloy wheels and the addition of illuminated badging to the back and sides. Unlike the Citigo-e iV, the Mii retains the mesh grille fitted to the petrol car.
