Shock of the show today has been an all-new unexpected city car concept from the world’s largest car manufacturer.

The Toyota IQ will go head-to-head with the Fox-replacing VW Up! and challenge the Smart’s city-slicking supremacy.

Despite the relatively big 17-inch wheels and sporty looks, expect the IQ to be an emissions champion with a predicted sub-90g/km CO2 and a combined fuel consumption exceeding 80mpg.
