Actual dynamic frontal crush behavior from initial contact to maximum dynamic crush of 8 cars in 45% frontal overlap and 30 degree rigid barrier impacts at 50 and 56 kph respectively is compared with predicted responses from an overall frontal crush model. The actual and predicted acceleration-displacement responses show very similar patterns while comparisons of predicted and actual energy equivalent speeds show for the cars examined that 98% confidence limits between actual and predicted energy equivalent speeds are -8.2 kph to +6.0 kph for energy speeds up to 56 kph where energy equivalent speed is the square root of twice the specific energy.
