Proposal to introduce new regional requirements from Contracting Parties, in particular from Euro 7 in the EU, including new particle number (PN10) provisions, a new SHED limit for evaporative emissions, updated On-board Fuel Consumption Monitoring provisions, and new annexes with requirements relating to in-vehicle battery durability and a new test for range of Pure Electric Vehicles at low temperatures for UN R154 (Worldwide harmonized Light vehicles Test Procedures (WLTP)).
Devices for monitoring on-board vehicle consumption of fuel and/or electric energy shall determine and store lifetime values of fuel consumed, distance travelled, and energy parameters specified in Appendix 5. Type-approval requires testing per Table A according to vehicle category and fuel type, including Type 1 emissions tests, evaporative emissions tests, durability, OBD checks, and OBFCM accuracy verification. Manufacturers must ensure OBFCM accuracy between −0.05 and +0.05 calculated using specified formulae comparing WLTP-determined and OBFCM-measured consumption. Conformity of production requires periodic testing and audits. Lifetime counter values shall be preserved from 1 January 2029 for new vehicle types; from 1 January 2030, type approvals for non-compliant vehicles shall not be accepted. OBFCM devices must provide standardised, unrestricted access to information via specified ISO and SAE standards.
TF-AVRS submitted a draft new Y-category Passive Safety Regulation to GRSP-79 in June 2026. The regulation addresses fuel system integrity, electrical shock protection, and crash compatibility for frontal, rear-end, and lateral collisions. The Task Force eliminated the R point problem, passenger compartment references, and A and B pillar designations, harmonised mass definitions, and consolidated numbering and cross-references. Open items include determining additional requirements, specific vehicle measurements, and finalising Annex elements. Subsequent informal documents are planned for GRSP-79, with working documents for GRSP-80.
Proposal to delete the draft “Reserved” paragraph 5.3.7.2.4.3. in GRVA/2026/18. Reserving paragraph 5.3.7.2.4.3. in the 01 series would mean that the subsequent paragraphs would be out of line with the numbering in the 02 series, making future amendments to UN R171 unnecessarily challenging.
Proposal to delete paragraph 1.2.6. excluding e-axle trailers with e-axles providing electric propulsion and/or incorporating an electric regenerative braking system from the scope of UN R13, and add definitions of “e-axle,” “e-axle trailer,” “dynamo function,” and “e-trailer”; add special requirements for power-driven vehicles supporting e-trailer operation, e-axle trailers equipped with dynamo function, and e-trailers of category O; add requirements for electric control lines conforming to ISO 11992-2:2027; specify message support and functional compatibility; and add provisions for electric regenerative braking, dynamo function, and propulsion, including parameters such as retarder torque demand priority, propulsion force limits, overriding mode activation at speeds below 15km/h, and vehicle stability function interaction.
Proposal to amend para. 3.5.1. of Annex 4 to require the manufacturer to demonstrate to the approval authority that effective processes, methodologies and tools are in place, up to date and being followed within the organization to manage the safety and continued compliance throughout the product lifecycle, and to demonstrate to the approval authority at least every three years that the safety management system continues to comply with these requirements.
In January 2022, an M1 passenger vehicle with a detached tyre caused its Anti-lock Braking System to activate, preventing effective braking and resulting in collision with a stationary lorry. The coroner concluded the ABS functioned as intended but created an unsafe scenario by using the fastest rotating wheel as reference speed, and recommended changes to prevent future deaths. The UK proposal to amend UN R13-H would require manufacturers to affirm that strategies to achieve system objectives will not prejudice safe operation of systems under non-fault conditions, including failures of other systems involved in achieving system function such as tyres or wheels, and that documentation be supported by analysis showing how the system will behave upon any fault with bearing on vehicle control, performance, or safety, including faults with other systems involved in achieving system function.
OICA-CLEPA-EME comments on German proposal GRVA-25-07 to require the approval authority granting UN R155 or UN R156 type approvals to use CSMS or SUMS certificates signed by the same approval authority. OICA-CLEPA-EME identify that CSMS and SUMS are Management Systems covering entire manufacturer organizations, and mandating the same approval authority for Management Systems certificates and approvals will have significant consequences for original equipment manufacturers typically using multiple approval authorities in homologation. The submission proposes keeping text unchanged to allow different approval authorities for Management Systems certificates and type approval based on voluntary acceptance, implementing wording on information exchange if different approval authorities are involved, and establishing a horizontal approach for Management Systems with mutual recognition aspects considered.
The World Forum agreed to resume consideration of the proposals for amendment of UN Rules annexed to the 1997 Agreement for their possible adoption by AC.4. if any.
