What Changed

For 2021 Kia's all-new midsize sedan adopts a new (to the US) K5 nameplate replacing the long-running Optima name. Compared to the Optima, the K5 is about 2 in longer in wheelbase and overall length. The K5 is slightly smaller on the inside, losing about 3 cu-ft. of passenger volume. All but the top sport models equip a 180-bhp 1.6l turbo four mated to an eight-speed automatic whereas the K5 GT equips a larger 290 horsepower 2.5l turbo four and dual clutch 8-speed. AWD is optional on all but the GT trim level.
