The 45 % overlap rigid barrier, 30 degree angled barrier and full width barrier behaviour of 8 cars is examined in terms of their force/dynamic displacement and energy absorption/dynamic displacement responses. This examination shows that the car front under full width crushing can be divided with increasing crush depth into 3 regions, each of which can be regarded as having constant crushing forces. The 3 regions are associated with the car longitudinal members, the engine/rear front structure and the occupant compartment. The data shows that the longitudinal members and the occupant compartment crush at lower force levels than the engine/rear front structure.
