The Scion iA was available for a single year before Toyota shut down the Scion brand. It debuted for the 2016 model year as a small sedan with peppy performance and a 1.5-liter four-cylinder engine. Although its powerplant makes just 105 horsepower, the lightweight Scion iA can be zippy and enjoyable to drive. It has a large trunk, but back-seat space is limited. The iA comes with forward-collision warning, which was a rarity in the segment at the time the car was manufactured.
