What is the main purpose of the chassis and bodywork regarding the vehicle's passive safety?

Question

DentroTest · Accepted Answer

From the point of view of passive safety (elements that act to minimize damage once an accident has occurred), the vehicle's structure is vital. The chassis and bodywork are designed with 'crumple zones'. This means that in the event of a collision, these parts must crush and deform in a controlled manner to absorb most of the kinetic energy of the impact. By dissipating this energy, it prevents the full force of the crash from being transmitted directly to the occupants, keeping the passenger compartment (the safety cell) as intact as possible. While an aerodynamic design reduces fuel consumption, that is a function of efficiency, not direct safety during an impact.
