2021 Kia K5
Kia says goodbye to the Optima, and hello to the K5. The sedan features an all-new platform, a slick new fastback look, and a lower, longer, and wider stance. Two turbo-4 engines will be available: a 1.6L with 180 hp and 195 lb-ft. torque (FWD or AWD), and a 2.5L with 290 hp and 311 lb-ft. torque, which comes standard on the K5 GT.
