The structural design of current vehicle front units has to account for an increasing number of constraints: improvement of real-world performance in safety for occupants and others road users, perform in the various ratings and meet future regulations. Therefore the structural car design is the result of a compromise between pedestrian protection, car-to-car compatibility and self- protection. In addition to these safety considerations, reparability constraints are becoming more and more demanding and intrusive toward the other safety requirements. The need to reduce emissions through fuel consumption control requires a reduction of the overall body weight which leads usually to more difficulties to achieve a correct structural behavior. Some of these constraints lead to solutions which are in opposition and in general to unsatisfactory compromises. It is suggested to develop a more comprehensive approach in order to better take into account both safety requirements and reparability.
