Proposal to cover all types of electric vehicles (xEVs) in the provisions of ASEP (Annex 7) in UN Regulation No. 51.
6. Against this background, the expert from OICA presented in detail their proposal that includes EVs in the scope of ASEP provisions in Annex 7 to UN Regulation No. 51, together with supporting data (ECE/TRANS/WP.29/GRBP/2025/29, GRBP-82-06, GRBP-82-08, GRBP-82-09, GRBP-82-38). The experts of several Contracting Parties considered the OICA proposal as an excellent basis, but pointed out that they would need more time to study it and suggested to postpone taking a decision until the next session of GRBP in February 2026.
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.
