2018 Kia Optima Overview


The 2018 Kia Optima is a midsize sedan that competes with the Ford Fusion, Mazda6, Toyota Camry, and Honda Accord. This year, the Optima gains more standard safety features. Its trim level offerings have also been revised.

Five trims are now available: the LX, S, LX Turbo, EX, and SX Turbo.

Overall, the Optima has unconventional, yet sportier styling than its competitors. Its aggressive headlights align with the honeycomb grille, which create a ridged, yet unified shape. The base LX and LX Turbo trims feature a smiley frontend, while the S, EX, and SX trims have a more aggressive lower fascia with front LED fog lights. LEDs for the headlights, daytime running lights, and tail lights are also optional. Aside from the front fender garnishes, the body is smooth without much sculpted molding. The rear also looks athletic with its diffuser-style lower fascia. Power side mirrors with turn-signal indicators, a remote opening/closing fuel door, and 16-inch alloy wheels come standard. Other available features include heated side mirrors, a panoramic moonroof, a dual-pipe exhaust system, and larger 17- or 18-inch alloy wheels.

Under the Hood
The LX, S, and EX models use the same base 185-hp, 2.4-liter 4-cylinder engine, while the SX Turbo features a more powerful 247-hp, turbocharged 2.0-liter 4-cylinder. A 6-speed automatic is the only transmission option for both of these engines. The LX Turbo comes with a 178-hp, turbocharged 1.6-liter 4-cylinder option that is mated to a 7-speed dual-clutch automatic. This option gets the best EPA-estimated rating of 28/39 mpg city/highway.

The Optima’s interior has an upscale feel much like the Cadenza and K900 sedans. Now standard is the UVO infotainment system, which includes a 7-inch touchscreen, Apple CarPlay/Android Auto compatibility, Bluetooth connectivity for phone and audio, and a USB port. It can be upgraded with a larger 8-inch touchscreen, a navigation system, voice command recognition, dual USB ports, and a Harmon Kardon premium audio system. Standard features include power doors/locks, remote keyless entry, cruise control, air conditioning, and a 60/40-split folding rear seat. Also available are premium leather or leatherette upholstery, dual-zone automatic climate control, a heated steering wheel, heated/ventilated front seats, and heated rear seats.


Standard safety features now include a backup camera, rear parking sensors, and blindspot monitoring with rear cross-traffic alert. An Around-View Monitor is available, which displays a top-down view of the Optima using four cameras mounted around the vehicle. Other optional features include adaptive cruise control, lane departure warning, and forward collision warning with automatic emergency braking.
