| Year | Body/Powertrain | Comment |
| 2007 | 4dr Sedan 161-horsepower 2.4L I4 5-speed shiftable automatic FWD |
Spacious enough to allow my 84 year old mother to get in and out without injuring herself! see full Kia Optima review |

After driving the Optima for five days straight for 10+ hours per day, other than the occasional stop, on a road trip, not one time did I get a sore back or thighs. see full Kia Optima review |
