The passenger compartment of the IONIQ 5 remained stable in the frontal offset test.  Dummy numbers showed good protection of the knees and femurs of both the driver and passenger.  Hyundai showed that a similar level of protection would be provided to the legs of occupants of different sizes and to those sitting in different positions.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the IONIQ 5 would be a benign impact partner in a frontal collision. In the full-width rigid barrier test, good protection was provided to all critical body areas of the driver and at least adequate protection for the rear passenger. In both the side barrier test and the more severe side pole impacts, protection of all critical body areas was good or adequate. The IONIQ 5 has a centre airbag to mitigate occupant to occupant injuries in the event of a lateral collision.  In Euro NCAP’s test, the airbag worked well, with good protection of the dummies’ heads.  Limitation of the extent to which a body is thrown to the other side of the car in a side impact was rated as marginal.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  A geometric analysis of the rear seats also indicated good whiplash protection.  The IONIQ 5 has, as standard, an advanced emergency call system which alerts the emergency services in the event of a crash. The car also applies the brakes after a collision to prevent secondary impacts.

In the both the frontal offset test, protection of both child dummies was good or adequate for all body regions.  In the side barrier test, protection was good for all critical body areas.  The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in that seating position.  Clear information is provided to the driver regarding the status of the airbag and the system was rewarded.  All of the child restraint types for which the IONIQ 5 is designed could be properly installed and accommodated in the car.

The protection provided by the bonnet to the head of a struck pedestrian was mostly good or adequate.  Poor results were recorded at the base of the windscreen and on the stiff windscreen pillars.  The bumper provided good protection to pedestrians’ legs at all test locations.  However,  protection of the pelvis was poor, and the IONIQ 5 scored no points in this area of assessment.  The autonomous emergency braking system of the IONIQ 5 detects vulnerable road users, as well as other vehicles.  The system’s response to pedestrians was adequate and its response to cyclists was good, with collisions avoided or mitigated in most test scenarios.

A seatbelt reminder is standard for the front and rear seats and a driver monitoring system monitors steering inputs for signs of fatigued driving.  The autonomous emergency braking system showed good performance in tests of its reaction to other vehicles.    A more advanced AEB system is available as an option which offers protection in additional situations but that system is not included in this assessment.  Speed assistance is provided by a system which informs the driver of the local limit, and which can automatically set the speed limiter to the appropriate speed. A lane support system gently corrects the course of a car which is drifting out of lane and also intervenes in more critical situations.
