As the Z4 is a two-seater, the assessment of child protection is based on the features available in the vehicle for safe transportation of children in the front passenger seat, and on the installation of various types of restraints in that seating position. The front passenger airbag can be disabled to allow a rearward facing child restraint to be used in that seating position. However, the information provided to the driver regarding the status of the airbag is not sufficiently clear and the system was not rewarded. All of the restraint types for which the Z4 is designed could be properly installed and accommodated.

The Z4 has an 'active' bonnet. Sensors in the bumper detect when a pedestrian has been struck and actuators lift the bonnet, creating more space between the surface and the hard structures in the engine compartment. BMW showed that the bonnet would deploy robustly over a range of speeds and for a variety of pedestrian statures. Accordingly, the bonnet was tested in the deployed (raised) position. Results were almost predominantly good or adequate on bonnet surface. The bumper offered good or adequate protection to pedestrians' legs and protection of the pelvis region was good at all test locations.
