Small overlap front: driver-side
Tested vehicle: 2018 Kia Rio LX 4-door
Rating applies to 2018-23 models
The Kia Rio and Hyundai Accent were redesigned for the 2018 model year and are now built on the same platform. The driver-side small overlap frontal ratings apply to both the sedan and hatchback versions of the Rio as well as to the Accent, available only as a sedan beginning with 2018 models.

Small overlap front: passenger-side
Tested vehicle: 2018 Kia Rio S 4-door
Rating applies to 2018-23 models
The Kia Rio and Hyundai Accent were redesigned for the 2018 model year and are now built on the same platform. Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Hyundai/Kia. Ratings apply to both the sedan and hatchback versions of the Rio as well as to the Accent, available only as a sedan beginning with 2018 models.

| Passenger restraints and dummy kinematics The dummy’s head barely contacted the frontal airbag before sliding off the right side, leaving the head vulnerable to contact with forward structure. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. |
