crumple zone
Engineered collapse section
A crumple zone is a section of a vehicle designed to collapse and absorb impact energy during a collision, protecting occupants in the passenger compartment.
The front and rear of modern cars are engineered to crumple in predictable ways: The crumple zone did its job—the hood was destroyed but the cabin stayed intact.
