Kia describes the new Rio as longer, wider, and lower than the outgoing model. All Rios get a direct-injection 1.6-liter four cylinder, which makes 138 horsepower while turning in fuel efficiency of 30 mpg city and 40 mpg highway.

Kia will offer cabin tech such as a Bluetooth phone system and iPod connectivity in the Rio. The most intriguing feature is UVO, a Microsoft-powered system similar to Ford Sync, in that it offers voice command over paired phones and connected MP3 players.
