Abstract
This paper analyses the UK in-depth crash data collected under the Co-operative Crash Injury Study to identify the optimum crash conditions for an advanced frontal crash test procedure. The paper recommends that a revised frontal crash test should employ a crash test of at least 60 kph into a deformable block with at most a 40% overlap. This condition represents that of greatest risk of AIS 3+ injury. Frontal impacts are most frequently with other cars indicating that the deformable nature of a car should be simulated by a new frontal test procedure. (A)
