A new 2019 Kia Optima is vastly different from a used 2015 model. Kia fully redesigned the Optima for the 2016 model year, which is when several new infotainment features and driver assistance technologies were first introduced. The 2019 Optima now boasts a standard touch-screen infotainment system with Android Auto and Apple CarPlay, and standard blind spot monitoring, rear cross traffic alert, rear parking sensors, forward collision avoidance assist, lane departure warning, lane change assist, lane keep assist, and driver drowsiness monitoring.
