Workshop on frontal impact scheduled for Tokyo, Japan, 4-6 November 2026 will assess robustness, defined as the vehicle’s ability to protect occupants across variations in body height, weight, shape, and seating position in real-world collisions by maintaining structural integrity and effective safety systems. The workshop will explore conceptual ideas for procedures to assess robustness by complementing current specific requirements based on ATDs using a more holistic approach. Sessions will address issues requiring solution and regulatory solutions, including review of relevant regulations, clarification of roles of ATDs and HBMs, and conceptual ideas of future regulatory upgrades addressing brain injury, soft tissue neck injury, lower leg injury, thorax injury, submarining, abdominal loading injury, and lower severity collisions.

The EqOP-TF4 held its 5th meeting on June 25, 2026, with 41 participants. The agenda was adopted with one item removed, and previous minutes were approved. The chair presented an updated priority table assessing injury relevance, regulatory gaps, test capabilities, and potential safety benefits for prioritizing future frontal impact safety requirements. Japan will report on submarining and female injury patterns. A workshop is scheduled for November 4–6, 2026, in Japan. The next meeting is September 7, 2026.

Proposed prioritization framework for future frontal impact safety enhancements. A holistic assessment tool to evaluate candidate topics, identify regulatory gaps, and define priorities for future frontal impact requirements. Draft table template includes topics such as soft tissue neck, chest, abdomen, foot and ankle, hand and arm, submarining, rear seat row, driver seat, front passenger seat, low speed, robustness, multi-scenario testing, and virtual testing with human body model. The framework considers equity issues, relevance, current UN Regulations, available test and criteria, and identifies volunteers to prepare topics.

The agenda includes a progress-dashboard review, an updated study presentation on rear row and abdominal injuries, and preparation for a Japan Workshop in Tokyo in November 2026, covering priority table alignment, robustness definition and alignment, workshop agenda, pre-workshop preparation, and practical arrangements.

Regarding buses and coaches scope, delegates supported defining school buses as Special Purpose Vehicles, enabling inclusion without creating a harmonized international category. Comments are due by 14 August. The draft light vehicle UN Regulation was uploaded for review with comments due before or during the September in-person meeting in France. An in-person meeting is scheduled for September 2026.

The Informal Working Group on Automotive Life Cycle Assessment decided not to submit the Working Document for the 95th GRPE session. The Mutual Resolution will not be submitted for adoption at the October 2026 GRPE session due to unresolved issues and lack of consensus. The leading team will prepare a status report for October 2026 GRPE describing progress, current status, remaining issues, and proposed way forward. A revised Terms of Reference extending the IWG mandate will be prepared. An additional meeting may be organized to determine the future work programme.
