Since its creation in 1996, Euroncap evaluated more than 80 cars, ranging from small and city cars, to larger vehicles such as executive cars and people carriers (MPVs). The testing protocol comprises 3 types of tests: a frontal offset test against a deformable barrier, a 90° lateral impact with a moving deformable barrier, and - since March 2000 - a pole side impact. In addition a set of subsystem tests with impactors on the bonnet and the front face of the car are conducted to assess the pedestrian protection. The aim of this paper is to review the testing and assessment protocols and to compare them with those used in other NCAP systems in the USA, Australia, Japan and Europe. In particular, important Euroncap issues such as the stiffness of heavier vehicles that could be increased in the future, and the nature and weight of the modifiers are discussed. Ways to improve the system are suggested in relation with real-world accident data.

State of the art demonstrates that weight of vehicle increases with length of car body. Integration of powertrain in mid rear underfloor location enables to shorten car body by more than 0,5m and to save partially heavy longitudinal members. Underfloor integration of power train induces higher stance floor for more conviviality of passengers visibility. Safety factors are improved by lowering gravity centre, better repartition of front / rear masses during braking, easier management of crash by straighter and higher front longitudinal members and free front space. Space frame architecture simplifies light weight technologies application by using 2D bended aluminum profiles. Low investment is ensured by minimising castings application to suspension attachments and interlinking upperbody to underbody. Floor and external panels are designed for aluminum sheet stampings.
