The energy absorption system in a car is typically provided by which component?

• A. The engine
• B. The bumper
• C. The tires
• D. The brakes

Answer: (B)

In a crash, the goal is to manage the energy of the impact so forces on occupants are minimized. The bumper is designed to do exactly that by deforming in a controlled way, known as crumpling, to absorb and dissipate energy. This design creates a longer stopping distance and lowers peak forces transmitted to the passenger cabin. Modern bumpers work with other structural elements to spread out the energy safely. The engine’s job is to provide power, not to absorb crash energy. Tires primarily provide grip and support; they can cushion some impact through deformation, but they’re not intended as the main energy-absorbing system. Brakes slow the car by converting kinetic energy into heat during deceleration, but in a crash they aren’t the primary mechanism for absorbing crash energy within the vehicle’s structure.
