Presentation comparing results of Switzerland’s NExUS study on electric vehicles and internal combustion engine vehicles with RD-ASEP Sound Expectation Model predictions. NExUS study objective was to compare EVs with ICE vehicles of the same consumer segment to better understand EV modelling. Key findings show overall sound levels of EVs and modern ICEs are close under constant speed, while ICE sound is higher under low-speed acceleration. RD-ASEP SEM predictions align closely with NExUS measurements for both accelerated and constant speed conditions.
The workshop on frontal impact assessment in Tokyo, 4-6 November 2026, will address robustness, defined as the vehicle’s ability to protect occupants of varying body height, weight, shape, and seating position in real-world relevant collisions by maintaining structural integrity and effective safety systems so that the risk of injury is minimized for all types of people. The agenda includes review of relevant regulations, clarification of roles of ATDs and HBMs, and conceptual ideas for future regulatory upgrades addressing brain injury, soft tissue neck injury, lower leg injury, thorax injury, submarining, abdominal loading, and lower severity collisions. The workshop will develop an HBM-based robustness assessment matrix to complement current ATD-based requirements.
