The 74th EPPR Informal Working Group Meeting on Environmental and Propulsion Performance Requirements of L-category vehicles was held on 8 July 2026. Discussion focused on transposing UN-GTR No. 2 into UN Regulation 40, with the group agreeing to establish a Task Force for Euro 4 transposition and setting 21 August as the deadline for supplementary questionnaire information and Task Force feedback. The group continued information exchange on maximum power determination, battery electric vehicle range standardization using SAE J2982 procedures, and deterioration factors in GTR 23 on durability, with no new updates or conclusions reached on next steps for these agenda items.

The 72nd EPPR session (March 2026) adopted the revised agenda and previous meeting report without changes. The 02 series of amendments to UN Regulation No. 40, transposing UN-GTR No. 2 to Euro 3 emission level (GRPE/2025/22 as amended by GRPE-93-26), was adopted for submission to WP.29/AC.1 in March 2026 and subsequently adopted by WP.29 at its 198th session. The IWG-EPPR Terms of Reference were extended for two years until 2027. IMMA offered to prepare a draft 03 series of amendments to UN Regulation No. 40 for Euro 4, tentatively expected by early June. The group agreed to reconvene around that time. The group reviewed information exchanges on maximum power determination, battery electric vehicle range determination standardization, and deterioration factors in GTR 23 on durability. Next meetings are scheduled for June, July, and September 2026, with the 76th session in October 2026 coinciding with GRPE.
