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.

The large, premium 2014 Kia Cadenza sedan might seem pricey by Kia standards but compares well feature-by-feature with other premium makes.

The 2014 Mazda6 i Grand Touring outshines much of the competition in the battle for your midsize sedan dollars, hitting most of the right marks, but some of its luster is dulled by the more powerful and efficient turbo-diesel and i-ELOOP models just around the corner.
