With its all-new platform, the fourth-generation Rio sedan and hatchback sit lower, wider, and slightly longer than before. The changes bring increased passenger space for both the front and rear seats. Cabin technology makes a step forward, with the top-level EX trim benefiting from a 7-inch touch-screen infotainment system, along with voice recognition, and Android Auto and Apple CarPlay compatibility. The 1.6-liter, four-cylinder engine essentially carries over, though it sees horsepower decrease by 8 notches in the interest of fuel economy--a notable shortcoming with the last-tested Rio. Transmissions choices remain of a six-speed manual or automatic. A reworked suspension will hopefully address the stiff feel found on the previous model. Automatic emergency braking for city/urban speed will now be available.
