The passenger compartment remained stable in the frontal impact, the windscreen pillar moving rearward less than 2mm. Dual pretensioners restrained the dummies well and readings indicated that the knees and femurs of both the driver and passenger were well protected. Opel were able to show that occupants of different sizes, and those sat in different seating positions, would be similiarly well protected. The Astra scored maximum points for its protection of the front passenger occupant in the frontal impact. Protection of the chest was adequate in the side barrier impact and marginal in the more severe side pole test, with good protection of all other body regions in both tests. Protection against whiplash injuries in rear impacts was rated as good.
Based on dummy readings in the frontal and side impacts, the Astra scored maximum points for protection of the 3 year dummy. Forward movment of the head was well controlled. In the side barrier test, both dummies were properly contained by their restraints. The passenger airbag can be disabled to allow a rearward facing child restraint to be used in that seating position. However, information provided to the driver regarding the status of the airbag is not sufficiently clear. The dangers of using a rearward facing child seat in that position without first disabling the airbag are clearly explained in a label attached to the passenger's sun visor.
The car scored maximum points for the protection offered to pedestrians' legs by the bumper. However, the protection provided by the front edge of the bonnet was poor and scored no points in Euro NCAP's tests. In most areas likely to b struck by the head of a child, the bonnet offered marginal protection. In all areas likely to be struck by an adult's head, the bonnet provided poor protection.
Electronic Stability Control (ESC) is standard equipment across the whole of the model range as is a seatbelt reminder system for the driver and front passenger seats.
