Small overlap front: driver-side

Rating applies to 2018-23 models

Tested vehicle: 2018 Kia Rio LX 4-door

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.

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

Forces on the left lower leg and foot were high enough to indicate a moderate risk of injuries.

About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2018-23 models

Tested vehicle: 2018 Kia Rio S 4-door

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.
