SEAT is revealing an expansion to the Mii city car line-up with the first glimpse of an even more versatile five-door version.

The additional rear doors turn the super-compact Seat into a unique combination of exceptional driving fun, sporty design and outstanding functionality.

Of course, the new five- door Mii remains true to core Seat principles — meaning it's both a pleasure to drive and to own.

In either three or five- door form the Mii scores top marks for fuel consumption and emissions thanks to its lightweight design and efficient drivetrains.

This applies in particular to the newly-announced Mii Ecomotive.
