Scion's first four-door sedan is actually built by Mazda. It's based on the new Mazda2 (not sold in the U.S.) and is powered by a 106-hp, 1.5-liter four-cylinder hooked up to either a six-speed manual or 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 uses a laser sensor to help the driver avoid collisions. A backup camera is standard. Inside, the iA gets steering-wheel controls for the audio, a 7-inch center screen display controlled via a center knob, just like in current Mazda models. A navigation system is a dealer-installed option. The Scion brand has been discontinued after the 2016 model year. The iA is renamed the Toyota Yaris iA.
