2021 Kia K5
The 2021 Kia K5 wears a new badge like it’s the first day on the job at Best Buy. The four-door family sedan’s an upgrade from the former Optima, Kia tells us.
It looks the part, but is it different enough to put its kith and kin, the 2020 Hyundai Sonata, in its rearview mirror?
If you missed the executive summary, it goes something like this: Both the K5 and Sonata tap 4-cylinder engines and automatic transmissions for performance, but the Hyundai has a base inline-4 that Kia skips—while Kia gets all-wheel drive that for now isn’t offered on the Sonata. Sized like each other, they look very little alike, particularly inside, though both go full tilt on features and on warranty coverage. Both call U.S. factories home: the Hyundai hails from Alabama, the Kia calls Georgia home.
