Crumple zones, crush zones, or crash zones, are a structural safety feature used in automobiles, to absorb the kinetic energy from the impact during a collision by controlled deformation. This energy is much greater than is commonly realized. A 4,409 lb. car traveling at 37 mph.,before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 47 ft. crashing on to a solid concrete surface. Increasing that speed by 50% to 56 mph. compares...
