crumple zones (located in the front and rear of your car) are needed to absorb some of the impact force. Quite comparable to an airbag. According to newtons 1st law, an object in motion will stay in motion. this being said, if a car going at 100km/h came to an immediate stop (crashes) the bodies in the car will be thrust forward at 100km/h. If some of this impact force is absorbed by a crumpling bumper in the front of the car, then less force will be applied to the passengers
All your Newer car have crumple zones
crumple zones absorb impact damage to protect the passenger cell
Crumple Zones prevent damage or injury by supplying a place in the structure of the frame to crumple in an accident.
Crumple zones are zones built into cars that crumple in a controlled manner. The main crumple zones are at the front and the rear of a vehicle. On impact, they crumple up in a controlled manner, which stops the force energy reaching the occupants and injuring them. The crumple zone dissipates the energy Advantage :they save lives by stopping forceful energy Disadvantage: they can kill occupants in severe accidents because in high speed impacts they can dislodge the dashboard from the frame of the body Potential collapse of the footwells, trapping the driver and passenger Crumple zones can be recognised by bent body panels.
Crumple zones
The crumple zones of cars are normally at the front because it is estimated that 65% of the car impacts occur on the front side. The crumple zone is aimed at absorbing the impact of a crush to secure the passengers.

You would have to crash to use them.
By absorbing some of the energy.
seat belts and air bags
crumple zones are not different materials, they are strategically placed indentions in the body panels. these indentions collapse on inpact instead of becoming a projectile into the passenger compartment.
