Kia Rio SX in Amarillo, TX

For 2011, manual transmission availability shrinks to the base trim, on which it is the only available transmission option.

All 2011 Kia Rio models are powered by a 110-horsepower, 1.6-liter 4-cylinder engine, matched with either a standard 5-speed manual or available 4-speed automatic transmission, and all are front-wheel drive. With the 5-speed manual, the Rio returns 28 mpg city, 34 mpg highway in the EPA cycle. The Rio does slightly better with the automatic transmission, returning 36 mpg on the highway.The fun-to-drive aspects are emphasized in the Rio's economical design. The engine has continuously variable valve timing for responsiveness, while the power steering is engine-speed-sensitive. The suspension is tuned for a smooth ride and crisp control, with MacPherson struts and a stabilizer bar in front, combined with a semi-independent setup in back.The Rio has more interior space than most cars its size and also has a generous 11.9 cubic feet of cargo space in the sedan, 15.8 cubic feet in the hatchback Rio5. When the Rio5's 60/40 split-folding back seat is in the forward-flat position, cargo space is expanded to nearly 50 cubic feet. Inside, all models have an 8-way adjustable driver's seat with fold-down armrest, a versatile center-stack storage tray and rear mesh seatback pockets. A full set of side airbags--front seat-mounted side air bags and full-length side-curtain bags--are both standard; however, electronic stability control is not available and anti-lock brakes come standard on the LX trim and better.The base trim Rio sedan starts at right around $12,000, and is quite budget transportation. But even it comes equipped with mirror-integrated turn signals, SIRIUS satellite radio, and a USB port. The LX trim adds Bluetooth, a tilt steering column, air conditioning, 4-wheel anti-lock brakes and an "EcoMinder" indicator that helps the driver drive more economically. The SX adds 16" alloy wheels, fog lamps, heated power mirrors, a leather-wrapped steering wheel, power windows and door locks and remote keyless entry. The Rio5 is the hatchback version of the Rio. It adds about 4 cubic feet of cargo space, and is similarly equipped to the sedan in both LX and SX trims.
