The experimental safety vehicle presented by Renault embodies a global response to the problem of automotive safety by adopting a complementarity approach to the effects of active and passive safety at various speeds. The vehicle was developed from research work in every area of safety making use of a wide range of new investigative tools such as non-linear calculation. The field of application for the technological progress applied to this vehicle is particularly wide. It includes structure of the vehicle, occupant restraints, vehicle behavior, interior conditions and indication to other vehicles. The safety synthesis vehicle will be evaluated from the point of view of passive safety in more severe conditions than the regulations prescribe. For active safety, the intention is to provide the vehicle with the ability to avoid accidents by giving it an optimum dynamic behavior capability.
