Considering car-to-car near-side collisions and occupants without side airbag protection, the real life data showed that the risk of AIS3+ injury was highest for the thorax followed by the pelvis and head. For both non-senior and senior occupants, most AIS3+ thorax injuries were sustained at crash severities ranging from 20 km/h to 40 km/h in lateral delta-v. In this interval, senior occupants were found to have approximately four times higher risk of AIS3+ thoracic injury than non-senior occupants. Current legal and rating tests include impact speeds and lateral delta-v in the range of 45 - 55 km/h and 20 - 35 km/h respectively. Within this range, car-to-car tests were performed with modern cars equipped with side airbags and older cars without. The AIS3+ thorax injury risk and also door intrusion speed were found to be considerably lower in the modern target car. Car-to-car tests were also performed with modern cars at crash severities higher than expected in current legal and rating tests. The structural integrity of the impacted car showed a potential for improved side impact protection by interior countermeasures. Consideration should then be made to senior occupants while not jeopardizing the current protective performance. The WorldSID used was able to produce what seems to be valid measurement data also at the higher impacts speeds.
