The insurance rating has been differentiated in grades according to cost of repair for damaged vehicles and has been an important consideration point for customers, when they buy a new vehicle. The RCAR (Research Council for Automobile repairs) has evaluated low speed damageability and reparability of vehicle. Vehicle manufacturers are going to try to reduce the repair cost by designing vehicles with the intent to minimize damage sustained in low speed crash. The absorbed collision energy to bumper system is important for the vehicle which has bumper system with upper bumper and lower bumper system. If upper crush can and lower crush can has not suitable load distribution ratio, the vehicle body has permanent deformation. This paper demonstrates an important thing of load distribution ratio by vehicle load path. Then vehicle body has not permanent deformation and reducing repair cost and improving damageability.
