The passenger compartment remained stable in the frontal impact. Dummy readings indicated good protection of the knees and femurs of the front seat occupants. Audi showed that a similar level of protection would be available to occupants of different sizes and to those sat in different positions. Maximum points were scored in the side barrier test. In the more severe side pole impact, protection of the driver's chest was rated as adequate. The front seats and head restraints provided good protection against whiplash injury in the event of a rear-end collision.
Both dummies were properly contained by their rearward facing child restraints in the front and side impacts, minimising the risk of contact with parts of the car interior. Although the passenger airbag can be disabled with an optionally fitted switch to allow a rearward-facing child restraint to be used in that seating position, insufficient information is provided to the driver regarding the status of the airbag preventing any reward for the system. Permanently attached labels on the sun visor clearly warn of the dangers of using a rearward facing child seat in that position without first disabling the airbag.
Good protection was provided by the bumper to pedestrians' legs and the car scored maximum points in this and the area likely to be struck by a child/small adult. In those areas likely to be struck by an adult's head the protection offered by the bonnet was predominantly marginal and poor, as was the bonnet leading edge where a pedestrians upper leg would impact.
Electronic stability control is standard equipment and met Euro NCAP's test requirements. A seatbelt reminder system is standard equipment for the front and rear seats. A speed limitation device is not currently available on the Audi A3.
