Moving up to the 2008 Kia Optima LX V6 gets you a more powerful 2.7-liter, 185-hp DOHC V6 engine matched with a 5-speed shiftable automatic. It rates 182 ft-lbs of torque at 4000 RPM and reduces fuel economy to around 21/31 mpg. Otherwise, the front-wheel drive 2008 Optima LX V6 is much like the automatic four-cylinder version. Power locks, windows, and mirrors, wheel-mounted cruise and audio controls, a CD/MP3 player with audio input jack, intermittent wipers, tilt and telescopic steering, remote entry, and a tachometer are all standard. There are four cupholders, (two front, two back,), two 12V power outlets, and 60/40s split-folding rear seats. Trunk capacity tops out at 14.8 cubic feet, with a cargo light, net, and tie-downs providing extra convenience.

Riding on a four-wheel independent suspension, the 2008 Optima LX V6 upgrades to 16-inch alloy wheels with all-season tires, though 17-inch alloys are offered in an Appearance Package, along with a blacked-out grille, black headlamp housing, foglights, a trip computer, and leather steering wheel trim. Dual-stage front airbags, side impact, and side curtain bags for both rows are standard, as are 4-wheel disc brakes, halogen headlamps, and a tire monitor. Electronic brakeforce distribution, 4-wheel ABS brakes, and traction and stability control are optional. Also available are carpeted floor mats and a rear spoiler.
