5. The IWG RD-ASEP Subgroup on UN Regulations Nos. 51 and 138 reported on their activities with the aim to find a satisfactory solution for the sound emissions of electric vehicles (EVs) and to update both UN Regulations (GRBP-82-35). In particular, the Subgroup agreed on the introduction of EVs in the scope of Annex 7 (ASEP) and on the urgency to do so, since some EVs were already equipped with external sound enhancement systems. The Subgroup decided to use the OICA proposal (ECE/TRANS/WP.29/GRBP/2025/29) for further consideration and discussed two main points on UN Regulation No. 51: addition of optional sounds and sound pressure limits for EVs of categories M1 and N1. 10. GRBP recalled the status report of the IWG RD-ASEP Subgroup on UN Regulations Nos. 51 and 138 (GRBP-82-35) and the ensuing discussion (paragraphs 5-7 above). |
