The 2016 Kia Optima is a five-passenger midsize sedan. The LX model comes standard with 16-inch alloy wheels, full power accessories, cruise control, air-conditioning, a six-way power driver seat (with power lumbar), a tilt-and-telescoping steering wheel, a 60/40-split rear seatback, a rearview camera, a 5-inch central display, Bluetooth phone and audio connectivity and a six-speaker sound system with a CD player, satellite radio, a USB port and an auxiliary audio jack. Standard safety features on the 2016 Kia Optima include antilock disc brakes, traction and stability control, front-seat side airbags, a driver knee airbag, and side curtain airbags. A rearview camera is standard. The Uvo telematics system is standard on most trims, and includes roadside assistance, collision notification and driver restrictions and tracking for secondary drivers. The prevailing theme of the 2016 Kia Optima's driving experience is isolation. On one hand, this is a good thing, as the Optima exhibits a near-total lack of outside noise at cruising speed. The new chassis, extensive sound deadening and the optional laminated front windows do a remarkable job of keeping road, wind and tire noise at bay. Conversing at highway speeds requires little more than a whisper to carry your voice throughout the cabin. The interior is handsome and spacious, highly functional and accessible. The front seats are quite comfortable. The 8-inch touchscreen features large, easy-to-press virtual buttons and a sharp, legible picture. We like that the Optima utilizes physical buttons for navigating top-tier functions, as they require less concentration to operate accurately and safely on the road.
