Kia's 2021 K5 gets a shot in the arm with 290-hp GT trim
Pour yourself another cup of coffee, folks, because your next sleeper sedan could well be a Kia. No, we're not talking about the ballsy, $50K Stinger, but its volume-seller little brother, the 2021 K5. Wider, longer, and slightly lower, the erstwhile Optima seems determined not to be boring. The K5 embraces an edgy persona with a meaner front fascia and snazzy kinked running lights—Kia's hoping you think "tiger." Around back, the K5 uses a strip of lights connecting its taillights, a styling cue it shares with its Korean sibling, the Hyundai Sonata.
