Background: Recent studies identified new trends in frontal accident configurations, i.e.small overlap.Objective: This emerging type of crash represent a higher injury risk for the occupants compared to other frontal crashes due to the small interaction of the structural energy absorption elements.Method and Material: In response to this new accident reality, IIHS introduced a new type of crash test to evaluate crashworthiness: the Small Overlap Impact (SOI) test.Results: The purpose of this study is to analyze the accident trend in Spain to study the changes in the overlap in frontal crashes and identify crashworthiness similarities between an SOI crash test and a real crash.
