The fifth generation Optima's 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 & Android Auto and an optional 12-speaker Bose audio system.

Under the hood, engines mostly mirror that of the Sonata, but the Optima receives a high-performance 2.5L 4-cylinder turbocharged unit with 290 hp and 422 Nm of torque.
All-wheel drive is newly available, further distinguishing it from the Sonata.

Depending on the market, Advanced Driver Assistance Systems (ADAS) include Forward Collision-avoidance Assist (FCA), Blind-spot View Monitor (BVM) with Surround View Monitor (SVM) and Blind-spot Collision-avoid Assist (BCA), Smart Cruise Control (SCC) or Navigation-based SCC (NSCC), Lane Following Assist (LFA), Driver Attention Warning (DAW), and Highway Driving Assist (HDA).

On June 30, 2020, Kia unveiled the US-market Optima and announced that it would be renamed to K5, taking the name from the South Korean version.
Both the 1.6L and 2.5L Hyundai Smartstream engine family turbocharged Inline Four-Cylinder (I4) gasoline engines will be available with either Front Wheel Drive (FWD) or All Wheel Drive (AWD), and an eight-speed "Wet Clutch" automatic transmission.
Trim levels include LX, LX-S, EX, and GT.
United States specification models will be assembled at Kia's West Point, Georgia assembly plant (KMMG).
