Which feature is designed to deform during a crash to absorb energy?

• A. Unibody
• B. Datum plane
• C. Crush zones
• D. Torque wrench

Answer: (C)

Energy absorption in a crash comes from parts that deform in a controlled way, turning the car’s kinetic energy into work done to bend and crush metal. The feature designed for this purpose is the crush zones. They are placed at the front (and sometimes the rear) and engineered to buckle progressively when impact occurs. This controlled deformation slows the deceleration, reducing the peak forces transmitted to occupants and helping keep the passenger compartment intact. The unibody is the overall structure that provides strength and rigidity, but its deformation in a crash isn’t the primary, intentional energy-absorbing feature. A datum plane is a reference line used for measurements and alignment, not something that absorbs crash energy. A torque wrench is simply a tool for applying a specific torque and has no role in crash energy management.
