Abstract Recent crashworthiness studies in the EU and the USA found higher severity (deformation and occupant injuries) in frontal crashes when the vehicle was loaded outboard (small overlap). IIHS began a small overlap front crashworthiness evaluation in 2012. Two strategies to deal with the problems of cage intrusion and lateral motion were followed by manufacturers: sliding away from the barrier with lateral translation or absorbing energy with rotation. After several crash test and crashworthiness analyses, IDIADA determined the importance of identifying the forces applied in each structural element involved in small overlap crash. A need to know about how vehicles react to small overlap impact was identified, and in order to help manufacturers with vehicle development a small overlap barrier able to record forces was built. This barrier could obtain force information of each important structural vehicle element such as hinge pillar, footwell, rocker panel, etc. during the crash. The instrumented barrier helps to correlate simulation and improve elements in order to reduce cage intrusion and reduce occupant injuries. The load cells in the barrier are tri-axial in order to obtain information from the X, Y and Z axes; this being especially important at the corner of the barrier where the translation and rotation of the vehicle takes place. The results will help to analyse the forces involved in vehicle structural areas and the influence of energy absorption and lateral motion strategies will be analysed in order to have a better knowledge of the vehicle response under this crash situation.
