The basic elements of the Toyota ESV energy management system consist of silicone rubber-type front bumper shock absorbers, an efficient energy-absorbing frame, and upper members for preventing vehicle pitch during impact. The Toyota ESV proved to have satisfactory performance in an 80 km/h frontal impact against flat and pole barriers by adequately balancing the strengths of these elements and effectively arranging the energy-absorbing members of the frame. In addition, based on experiences with the ESV tests, the relationships between crashworthiness variations and vehicle weight or size were studied in detail.
