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.
Proposal to amend para. 2.12. to clarify the definition of power-operated windows, renumber para. 5.8.4.2. as 5.8.4.3., insert new para. 5.8.4.2. requiring window controls of power-operated side windows adjacent to the front seat row to be within reach and directly accessible, insert new paras. 5.8.8., 5.8.8.1., and 5.8.8.2. requiring power-operated side windows of the front seat row to remain operable in the opening direction for at least 2 minutes during vehicle submergence or automatically open within 30 seconds, with windows opening to maximum extent permitted, and insert new Annex 11 specifying submergence test procedures including container-based tests, slope-entry tests, and alternative subsystem tests.
Comments on draft UN R51.04 addressing various editorial and technical issues in Annexes 3, 6, 7, 8, and 9, including:
Draft minutes of the 13th IWG on EV/HFCV-RS meeting held 8 October 2026. The group reviewed the work program ahead of the forthcoming GRPE session scheduled for 14-16 October 2026, with the objective to provide GRPE with a first draft of the future UN Regulation. The latest draft Regulation was jointly reviewed, continuing technical discussions on provisions and addressing comments and proposals from stakeholders. Particular attention was given to the scope, type definition and testing requirements, and the presence of installer definition in the UN Regulation. Participants worked collaboratively towards consolidating inputs and preparing an agreed version of the draft for presentation at the next GRPE session.
