The 2010 Kia Optima is part of the vehicle's third generation. Offered in two trims, LX and EX, it comes standard with front-wheel drive and a 5-speed automatic transmission with Sportmatic shifting. Engine options include a 175-hp 2.4-liter four-cylinder or a 194-hp 2.7-liter V6. Standard features include keyless entry, cruise control, and a six-speaker audio system with CD player and Sirius Satellite Radio. All models come equipped with six airbags, stability control, brake assist, tire pressure monitor and anti-lock brakes for safety. Kia has made only minor changes to the Optima for 2010, with updates to the sedan's interior and exterior styling being the most significant.
