There's only one model available in the Rio 5-door range. The S is powered by a 1.6-liter four-cylinder mated to a CVT transmission. It's not the most powerful engine, but in this segment, frugality is far more critical. Standard exterior features include halogen headlights, a rear roof spoiler, and heated power-adjustable side mirrors. You also get remote keyless entry, power windows, a multi-function steering wheel with tilt adjustment, and a six-way manually-adjustable driver's seat. Seats are trimmed in premium cloth, while the interior plastics are of relatively high quality. The 2021 models come with an all-new eight-inch touchscreen infotainment system, boasting wireless Apple CarPlay and Android Auto.
