The passenger compartment of the Arona remained stable in the frontal offset test. Dummy numbers demonstrated good protection of the knees and femurs of both the driver and passenger.  SEAT showed that a similar level of protection would be provided to 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 Arona would be a benign impact partner in a frontal collision. In the full-width rigid barrier test, protection of all critical body areas was good for the driver and was good or adequate for the rear passenger. In the side barrier test, protection was good or adequate, and in the side pole impact, it was good for all critical body regions.  Control of excursion (the extent to which a body is thrown to the other side of the vehicle when it is hit from the far side) was found to be poor. The Arona does not have a counter-measure to mitigate against occupant to occupant injuries in such impacts. 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 Arona has an advanced eCall system which alerts the emergency services in the event of a crash. The car also has a system which applies the brakes after an impact to avoid secondary collisions.

Protection of the neck of the 10 year child in the frontal impact was rated as weak, based on dummy readings of tensile forces.  Otherwise, protection was good or adequate in both the frontal offset test and the side barrier impact.  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 restraint types for which the Arona is designed could be properly installed and accommodated.

The bonnet provided predominantly good or adequate protection to the head of a struck pedestrian, with some poor results recorded at the base of the windscreen and on the stiff windscreen pillars.  The bumper offered good protection to pedestrians’ legs but protection of the pelvis region was mixed.  The autonomous emergency braking (AEB) system of the Arona can respond to vulnerable road users, as well as to other vehicles.  The system performed adequately in tests of its response to pedestrians and cyclists.

The Arona’s autonomous emergency braking (AEB) system performed adequately in tests of its reaction to other vehicles.  A seatbelt reminder system is fitted as standard to the front and rear seats and the car has a system to detect driver fatigue.  The lane support system gently corrects the vehicle’s path if it is drifting out of lane, and also intervenes in some more critical situations.  A driver-set speed limiter is standard equipment.
