The Rio’s direct-injected engine is one of the more efficient engines its size, returning fuel economy ratings of 30 mpg city, 40 highway, and beginning later in the model year, all Rio models will also come with Idle Stop and Go Technology–Kia’s version of an engine start/stop system that will automatically stop the engine at stoplights, when your foot is on the brake, and restart it right as you lift off to accelerate away.
A new lightweight structure uses more high-strength steel, while the Rio’s suspension–MacPherson struts in front, with a stabilizer bar and a torsion-beam setup in back–is configured a good combination of nimble around-town handling and good passenger comfort. SX models get a somewhat stiffer, sportier calibration.
Overall, there’s no significant difference in seating space between the Rio sedan and hatchback models. However the sedan is about a foot longer, bringing an especially roomy trunk. But with their split-folding rear seatbacks, which free up a vast cargo hold when down, hatchback models are arguably a bit more versatile.
All 2012 Rio models come with six standard airbags, including front seat-mounted bags plus full-length side-curtain bags. Electronic stability control and anti-lock brakes are standard on the Rio, as is a Hill Start Assist Control system to avoid rolling back on uphill starts.
Rio LX models include steering-wheel audio controls, a trip computer, split-folding rear seatbacks, and a driver’s seat that’s height-adjustable. EX models add a host of popular features including a tilt/telescopic steering wheel, Bluetooth connectivity with voice commands, power windows, and upgraded trims. A Power Package is available on the LX, adding power windows and keyless entry, while a Convenience Package for the EX adds alloy wheels, and the UVO voice-activated, touch-screen infotainment system.
At the top of the model line, the Rio SX comes with power-folding outside mirrors, dual illuminated vanity mirrors, a rear camera system, and Kia’s UVO voice-activated infotainment system; plus the SX is dressed up with metal pedals, a leather-wrapped steering wheel and shift knob, an upgraded instrument cluster, LED front running lights and LED taillights.
