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 agenda includes adoption of EPPR-74-01 and EPPR-73-04, transposition of UN-GTR 2 into UN-Regulation 40 across Euro 3, 4, and 5 emission levels using documents GRPE-93-07-Rev.1, GRPE-92-12, GRPE-92-13, GRPE/2025/22, GRPE-93-26, EPPR-73-02, and EPPR-73-03, maximum power determination discussions using EPPR-22-15 through EPPR-59-04, battery electric vehicle range determination standardization using EPPR-53-04 through EPPR-59-03, and deterioration factors in GTR 23 using EPPR-56-04 and EPPR-65-05. Next meetings are scheduled for 7 September 2026 and October 2026 in conjunction with 95/GRPE.

The 73rd EPPR Informal Working Group Meeting on Environmental and Propulsion Performance Requirements of L-category vehicles was held 1 June 2026. The agenda and previous meeting report EPPR-72-03 were adopted without changes. The IWG discussed transposing UN-GTR No. 2 to Euro 3, 4, and 5 emission levels through incremental steps; the new 02 series of amendments to R40 was adopted by March 198/WP.29 (WP.29/2026/24), and IMMA presented a draft 03 series for Euro 4 level. The IWG agreed to identify legislative gaps via questionnaire due 26 June. Information was exchanged on maximum power determination, battery electric vehicle range determination standardization using SAE J2982, and deterioration factors in GTR 23 on durability. The next meetings are scheduled for 8 July 2026, 7 September 2026, and October 2026.

The agenda includes transposition of UN-GTR 2 into UN R40, with discussions on Euro 4 level amendments, maximum power determination for two-wheelers, battery electric vehicle range standardization using SAE J2982 procedures, and deterioration factors in GTR 23.

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.
