crumple zone

Region at the front and rear of a motor vehicle that is designed to crumple gradually during a collision, so reducing the risk of serious injury to passengers. The progressive crumpling absorbs the kinetic energy of the vehicle more gradually than a rigid structure would, thereby diminishing the forces of deceleration acting on the vehicle and on the people inside.

Similar to the crumple zones designed by the auto industry, the idea behind CEM is to have the structure of a rail car absorb the energy and shock of a crash rather than the bodies inside it.
For example, spidron reliefs could be used as shock absorbers or crumple zones in vehicles, Erdely says.
In addition, Smart Cars don't have crumple zones like most traditional models, which allows them to "hold their shape like a ball or nut," and they have other safety features such as skid control, anti-lock brakes and raised seat position.
