Hyundai modified the i30 to improve the protection of the driver's knees and femurs. Dummy readings for that body region were better than those of the earlier car, although points were still lost for structures such as the steering column and ignition barrel which could present a hazard to the upper legs of drivers of different sizes or those sat in different positions. The occupant compartment and driver footwell remained stable during the impact.
The passenger airbag can be disabled to allow a rearward facing child restraint to be used in that seating position. However, information provided to the driver about the status of the airbag is not sufficiently clear. The label warning of the dangers of using a rearward facing child restraint without first disabling the airbag was not clear and was visible only when the passenger's sun visor was stowed. The presence of ISOFIX anchorages in the rear seats was not clearly marked.
Protection for the head of a struck child was predominantly fair. However, protection of adults' heads was poor, as was the protection offered by the front edge of the bonnet.
