Adult occupant
The passenger cell of the Ampera remained stable in the frontal impact. The car has driver and passenger airbags as standard equipment and dummy readings indicated good protection of the knees and femurs of both front seat occupants. The Ampera scored maximum points in the side barrier test. The car also scored maximum points in the more severe side pole impact, the first car tested by Euro NCAP to do so, with good protection of all body areas. The protection provided by the seat and head restraint against whiplash injuries in a rear-end collision was marginal. The electrical safety of the car was checked after all of the impact tests and no problems were found.

Child occupant
Forward movement of the head of the 3 year dummy, sat in a forward facing seat, was not excessive and both dummies were properly contained by their restraints in the side impact test. 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 placing a rearward facing restraint in the passenger seat without first disabling the airbag are clearly explained in a permanently attached label.

Pedestrian
The bumper offered good protection to pedestrians' legs and the bonnet was mostly good in those areas likely to be struck by the head of a child. However, no points were scored by the front edge of the bonnet and the bonnet surface offered almost entirely poor protection to the head of a struck adult.

Safety assist
The Ampera has electronic stability control as standard equipment and is fitted with a seatbelt reminder for the driver, front passenger and rear seats.
