Crumple zones are engineered to manage crash energy so the cabin isn’t forced to take the full impact. You’ll see results from major programs—IIHS, NHTSA, and Euro NCAP—covering head and chest injury metrics, side intrusion, and how real-world fatality and severe-injury trends shift. Then the page breaks down the mechanics and materials behind the deformation, and how standards define performance targets for different crash speeds and modes.
