The fifth generation Optima is badged as the K5 worldwide. Its overall design is similar to that of the Sonata, with a fastback-like profile, a trend that began in the 1940s. However, the styling is unique, featuring Z-shaped running lights, a textured grille and a chrome strip that runs along the window line and becomes more prominent at the C-pillar. The interior has been redesigned significantly as well, with an optional 12.3-inch digital cluster and 10.3-inch center screen, augmented by Apple CarPlay and Android Auto and an optional 12-speaker Bose audio system.
