The Scion iQ is one of the smallest cars on the market and it has its sights set on the Mercedes-Benz smart. Despite its reduced size, the silhouette is very nice. The designers have even found a way to create two seats in back, although only one is usable thanks to the ingenious placement of the front passenger seat. A 1.3L four-cylinder engine is paired with a continuously variable transmission that activates the front wheels. It goes without saying that this car is meant for the urban environment.
