👉 The Bumper IOR, or Bumper International Rating, is a standardized test used to evaluate the performance of vehicle bumpers in crash safety. Developed by the Insurance Institute for Highway Safety (IIHS), it measures how well a bumper absorbs and dissipates energy during a frontal impact, simulating the forces experienced in a collision. Vehicles are tested with dummy heads that mimic human occupants, and the Bumper IOR assesses metrics such as the amount of force transmitted to the dummy, the duration of the crash, and the overall deformation of the bumper. This rating helps consumers understand the relative safety of different bumpers and aids manufacturers in improving vehicle design to enhance occupant protection.
