For 2017, the Scion iA is renamed the Toyota Yaris iA. This four-door sedan is actually built by Mazda and is based on the new Mazda2 (not sold in the U.S.). It is powered by a 106-hp, 1.5-liter four-cylinder coupled to either a six-speed manual or an automatic. In our testing we got 35 mpg overall with the automatic. The iA proves to be quite pleasant for a subcompact, with nimble handling and semi-decent interior decor. It also comes with a standard low-speed pre-collision system that helps the driver avoid collisions. A backup camera is standard. Just like in current Mazda models, the infotainment system consists of a center control knob and a screen, which takes some getting used to in order to master.  2018 was the final year for the Yaris iA.
