The passenger compartment of the Clio remained stable in the frontal test. Dummy readings indicated good protection of the knees and femurs of both front seat occupants. Renault showed that a similar level of protection would be provided to occupants of different sizes and to those sat in different positions. In the side barrier test, the car scored maximum points, with good protection being offered to all body regions. However, in the more severe side pole test, dummy readings of rib compressions indicated weak protection for that body region. The seat and head restraint provided marginal protection against whiplash injury in the event of a rear-end collision.
The Clio scored maximum points for the protection provided to the 18 month dummy in the dynamic impact tests. Forward movement of the 3 year dummy, sat in a forward-facing restraint, was not excessive. In the side impact, both dummies were properly contained by their restraints, minimising the risk of the head contacting parts of the car interior. The passenger airbag can be disabled to allow a rearward-facing 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 by Euro NCAP. The dangers of using a rearward-facing child seat in that position without first disabling the airbag are clearly explained in the vehicle.
The bumper provided good protection to pedestrians' legs and scored maximum points. Protection offered by the front edge of the bonnet was predominantly good. In most of the areas likely to be struck by a child's head, protection was poor or marginal. Similarly, marginal or poor protection was provided by the bonnet in those areas likely to be struck by an adult's head.
Electronic stability control is standard equipment on all Clios and the system met Euro NCAP's test requirements. A seatbelt reminder system is standard for the front and rear seats and a driver-set speed limitation device is also fitted to all Clios.
