Adult occupant
The passenger compartment remained stable in the frontal impact. Dummy readings indicated good protection of the front seat occupants' knees and femurs. Additional tests demonstrated that a similar level of protection would be offered to occupants of different sizes and to those sat in different positions. In the side barrier impact, compression of the dummy's ribs indicated marginal chest protection, despite the presence of a thorax airbag. However, chest protection was rated as adequate in the side pole impact, normally a more severe test than the side barrier impact. Protection against whiplash injuries in the event of a rear end collision was rated as marginal.

Child occupant
Based on dummy readings in the dynamic tests, the A1 scored maximum points for the protection offered to the 3 year dummy. Forward head movement was not excessive in the frontal impact and both the 3 year and 18 month dummies were properly contained by their respective restraints in the side impact. A switch is available as an option which allows the passenger airbag to be disabled, allowing a rearward facing child restraint to be used in that seating position. The test vehicles were not equipped with the switch so a full assessment could not be made. However, information in the vehicle handbook indicated that the system would not meet Euro NCAP's requirements as there is insufficient information close to the switch. The label warning of the dangers of using a rearward facing restraint without first disabling the airbag was unclear, poorly positioned and not permanently attached.

Pedestrian
The A1 scored maximum points for the protection offered by the bumper to pedestrians' legs. However, the front edge of the bonnet was poor in almost every area tested. The protection provided by the bonnet was rated as good in most areas where a child's head might hit. However, for those areas likely to be struck by an adult's head, the protection offered was predominantly poor.

Safety assist
Electronic stability control is standard equipment on all variants. A seatbelt reminder system covering both front and rear seats is also standard and fully complied with Euro NCAP's requirements, receiving maximum points.
