“The ES 300 and Camry are essentially the same cars with similar bumper systems, so it’s not surprising that their performances in the 5 mph tests also were similar. The biggest difference was in the pole test. The rear bumper systems on both cars include steel inserts in the middle of the foam in the rear bumpers. This energy-absorbing insert, placed exactly where the car hits the pole in the Institute’s test, would manage the energy of a low-speed crash in only a narrow range of impacts, so the pole tests of these vehicles were conducted slightly off-center.”
