This paper compares the differences between the new and old protocols, while analyzing the effect of these changes on pedestrian safety vehicle design. Two different car models were evaluated using the old protocol and the new protocol. The influences were also analyzed on different vehicle front end styling design, different vehicle packaging, and different vehicle bonnet structure design. The results show that the new protocol has less limitation to vehicle front end styling design but more requirements for the vehicle front end hard points packaging and the vehicle structure design. These results can be used as guides for vehic
