The Kia Optima is based on the same platform as the recently updated Hyundai Sonata. Compared to the previous Optima, the new version looks far more upscale than its price would suggest. Unlike its sister sedan, the Optima has a more curvaceous front fascia that is significantly more sporty than the conservatively angular Hyundai. Kia aims to attract a younger, less affluent buyer for the Optima, so the 3.3L V-6 is reserved for the Sonata. Nonetheless, the smaller 2.7L V-6 combined with the optional 5-speed automatic should be adequate for most customers. The midsize Optima offers more room and standard features than other competitors in its price range, and is a credible family sedan value.

The 2009 Optima wears updated front and rear styling. The overall length is about 2 inches longer. A new 2.4-liter four cylinder engine produces 175-bhp an increase of 13-bhp. The output of the 2.7L V6 increases to 190-bhp. On the inside, the Optima features modest updates to the instrumentation and center console materials. A new SX sport model adds a sport-tuned suspension, fog lights and 17-inch wheels.
