The passenger compartment of the Aygo remained stable in the frontal offset test.聽 Although dummy readings were good for the knees and femurs of both the driver and passenger, structures in the dashboard were thought to present a risk to occupants of different sizes and to those sat in different positions, so the protection provided to this part of the body was downgraded to marginal.聽 In the full-width rigid barrier test, protection of the head, neck and chest of the rear passenger dummy was rated as poor and no points were scored for this dummy.聽 Protection of the driver dummy in the same test was good or adequate.聽 In both the side barrier impact and the more severe side pole test, protection of all critical parts of the body was good, and the Aygo scored maximum points.聽 Tests on the front seats and head restraints demonstrated good whiplash protection in the event of a rear-end collision.聽 A geometric assessment of the rear seats indicated marginal whiplash protection.聽 The Aygo has an autonomous emergency braking system as part of an option pack, an assessment of which is not included in this rating.
