The passenger compartment remained stable in the frontal impact. Structures in the dashboard presented a risk of injury to the knees and femurs of the driver and passenger. Based on dummy readings alone, the Soul scored maximum points for its protection of the driver in the side barrier test. However, the driver's door was not fully latched after the test and the car was penalised a point. In the side pole test, protection of the chest was marginal. However, good protection was provided against whiplash injuries.
Based on dummy readings, maximum points were scored for the protection provided to both the 3 year and the 1½ year children in the frontal and side impact tests. Forward movement of the head of the 3 year child, sat in a forward-facing seat, was not excessive in the frontal impact the heads of both dummies were contained by the restraints in the side 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 regarding the status of the airbag is not sufficiently clear.
The front edge of the bonnet offered poor protection to pedestrians' legs. In most areas likely to be hit by a pedestrian's head, the bonnet also provided poor protection. Only the bumper offered predominantly good protection against injury.
Electronic stability control is standard equipment on all Kia Souls, as is a seatbelt reminder system for both front and rear seats.
