Nowadays, the development of new vehicles always requires an extensive research in Passive Safety Systems to ensure that the injury risk for vehicle occupants towards crash accidents is always kept as low as possible. Year by year, Passive Safety Regulations and Standards have become more demanding and have gained a greater importance. It is for this reason that there has been a remarkable change in ail Euro NCAP Crash Test Protocols, introducing the use of new Crash Test Dummies. The aim of this paper is to focus on the modifications found in Side Impact Crash Tests and, more specifically, on the 50%ile male WorldSID dummy. For many years, all Side Impact Crash Test studies have been put into practice considering the results achieved from the EuroSID II dummy. The introduction of the WorldSID to the crash test world has become a milestone not only for vehicle manufacturers but also for crash test laboratories. Because of this, it has been decided to study the differences between the EuroSID II dummy and the new dummy to be used hereinafter. In order to develop this comparison, an in-depth analysis of the structure of the WorldSID, its components and its instrumentation has been accomplished so as to obtain a clearer global view of what can be expected of the values achieved from testing the dummy. Furthermore, a series of impact tests have been performed, using the EuroSID II and the WorldSID; making a special effort to dispose of test results from both dummies in very similar configurations. The results from these comparative tests have been used to evaluate the presence of a correlation between the injury values that may be obtained from one test dummy and from the other. This procedure has been carried out considering the injury criteria assessment values that are established in Euro NCAP Side Impact Protocols. As a result of the abovementioned tests, it will be possible to compare the injury criteria values corresponding to both dummies, and to evaluate if there is a direct relationship between the results that may be gained from one and the other. By comparing the impact that the side impact crashes can have on the individuals, and knowing that the WorldSID dummy has a higher tested biofidelity than the EuroSID II, it will be able to discern if there are any weaknesses in the Passive Safety developments that have been done up to date. In this way it will be easier to improve the safety of future cars. Nevertheless, WorldSID is a new dummy that has been recently introduced in the crash testing market. Therefore, it is susceptible to future improvements that may generate modifications in the results that can be reached from testing the present version of the WorldSID dummy. In conclusion, crash test laboratories and vehicle manufacturers must promptly adapt themselves to the upcoming Passive Safety Protocols. The availability of a clear result in the comparison between the EuroSID II dummy and the WorldSID dummy will make it possible to direct future Vehicle Passive Safety Analysis towards the correct path, ensuring an improvement in the biomechanical values and lowering the amount of injury risks that are subject to any kind of side impact crash.
