2011 Kia Optima EX compare

The larger, more powerful 2011 Kia Optima EX has grown into a serious challenger in the midsize sedan market with a high level of cabin appointments at a relatively low price.

The 2011 Kia Optima SX makes the midsize sedan interesting through fine cabin appointments, plenty of power, and unique exterior styling.

Among midsize sedans, none is as technology-rich as the 2013 Ford Fusion, which mixes efficiency, driver assistance, and infotainment features in one attractive package.

The 2013 Honda Accord EX employs well-engineered drivetrain technology, but Honda reserves most of the electronic gadgetry for the Accord's higher trim levels.
