The 2009 Kia Optima is presented with new front, side and rear styling cues, which build upon Kia's philosophy of creating dynamic vehicles that evoke passion. The fog lamps and lower front grille have been enlarged and the headlamps narrowed to create an aggressively sharper look. Wider side garnishes add sportiness while the acute front lines continue toward the back, ending on a distinctly edged trunk lid. To complete the redesigned rear fascia, taillights are narrowed to enhance Optima's sleeker cosmetic appearance.

Also, new for 2009 is the addition of the sporty SX trim, which complements the handsomely-equipped, value-priced LX and luxury-oriented EX trims. Already available with Kia's Rio, Rio5, Spectra and Spectra5 models, the SX line provides another dimension for Optima buyers looking for a sportier midsize. Along with a sport-tuned suspension, SX upgrades include: a black-bezeled front grille and headlamps, LED outside-mirror turning signals, fog lights and hyper-silver-finished 17-inch wheels. EX and LX V6 models are equipped with 16-inch alloy wheels, and are fitted with Goodyear tires.

The 2009 Kia Optima's overall length also increased, extending nearly two inches in the front and one inch in the rear, to an overall length of roughly 189 inches. The larger proportions enhance the exterior styling for a lower, leaner, more powerful stance. All other dimensions, including wheelbase, remain unchanged.
