Seat has revealed its new Mii city car which will go on sale in the UK with a three-door version at the end of this year and then a five-door model in spring 2012.

The Mii is the second model to be based on Volkswagen’s new Up, following Skoda’s Citygo.

The new Seat will be offered with all-new 1.0-litre petrol engines of 58bhp and 73bhp outputs.

The Mii Ecomotive will have CO2 emissions of 97g/km and will feature a Seat portable system which brings together entertainment, navigation, phone and vehicle functions on a five-inch screen which can be removed from the centre console.

Prices will be revealed closer to launch.
