This paper arises from the observations of several accident investigators that not many more fatalities in cars can be saved in present day traffic and speed conditions, because intrusion of damage is extending right back into the occupants in many cases. Even air bags cannot perform as intended in these circumstances. Therefore it is proposed that the fronts of all vehicles are matched in respect of their height above road level (350mm to 550mm and then to 700mm) as well as to their structural stiffnesses when impacted. The initial proposal is that this matching extends back 700mm from the front face, although the proposal would be improved if this could be increased. The frontal structure is based on the needs in impact of the small car and the implications are discussed in this paper .
