2024 Kia K5
midsize car / 4-door sedan
Small overlap front
The small overlap front evaluation consists of a driver-side and a passenger-side component. If the results of the two evaluations differ, then the combined small overlap rating is equal to the lower rating.
Driver-side
- Rating applies to 2021-24 models
Tested vehicle: 2021 Kia K5 LXS 4-door
The Kia K5 was introduced in the 2021 model year, replacing the Optima nameplate in the Kia lineup. Driver-side small overlap frontal ratings are assigned by the Institute based on a test of a 2021 K5 conducted by Hyundai/Kia.

View of the vehicle after the crash showing the airbags and damage to the occupant compartment.
The rear passenger dummy's head remained a safe distance from the front seatback.
Rear passenger dummy injury values indicate a likely risk of injury to the head or neck and chest. During the crash, the shoulder belt remained in an ideal position on the dummy’s chest.
The rear passenger dummy's lap belt moved from the ideal position on the pelvis onto the abdomen, increasing the risk of abdominal injuries.

| Distance at which headlights provide at least 5 lux illumination: | |
Low beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good in all 4 tests.
The low beams never exceeded glare limits.
High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good on the gradual left and both right curves and fair on the sharp left curve.
High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway.
