Field test of on-board diagnostics (OBD) use during periodic emission testing for Euro 5+ motorcycles. Fifty-three Euro 5+ motorcycles were tested to examine feasibility and practicability of OBD-based inspection procedures. All motorcycles had 6-pin or 16-pin connectors. Challenges included locating OBD ports, accessing them with mechanical tools, engine coolant temperature readouts for oil/air-cooled motors, revving to 2500 rpm on some scooters, and measuring lambda with short exhaust systems. OBD information improves periodic technical inspection reliability for Euro 5+ motorcycles.

Status report on the Informal Working Group on Environmental and Propulsion Performance Requirements for L-Category Vehicles. The IWG-EPPR has established a Task Force to transpose UN-GTR No. 2 into the 03 series of amendments to UN Regulation No. 40, co-chaired by Japan and Malaysia with JASIC and IMMA as co-secretaries. The Task Force held its first meeting on 9 October with participation from ASEAN countries, Ghana, and others, and agreed on workplan and rules of procedure. Target dates for deliverables are April 2027 and October 2027.

The first task force session confirmed the scope of work, organization structure, and timelines for developing UN R40.03 to transpose Euro 4-level requirements from UN GTR No. 2 into UN Regulation No. 40 and to ensure administrative provisions necessary for mutual recognition and type approval. The Task Force agreed to use IMMA proposal EPPR-73-02 as the technical baseline, identified provisions already aligned with GTR No. 2 and those requiring revision, and established a working method for future discussions. TF-02 is proposed for 24 November 2026 and will examine the main text from paragraph 1 through paragraph 12, including Appendix 2.

Draft agenda for the 76th EPPR Informal Working Group Meeting on Environmental and Propulsion Performance Requirements of L-category vehicles, scheduled for 13 October 2026. The agenda covers adoption of the previous meeting’s report, transposition of UN-GTR 2 into UN Regulation 40 with feedback from multiple countries, information exchange on maximum power determination for two-wheelers, battery electric vehicle range determination standardization, deterioration factors in GTR 23, and other business items.

Draft report of the 75th meeting of the EPPR informal working group on environmental and propulsion performance requirements of L-category vehicles. The group adopted the previous meeting’s report and agenda. A Task Force was established to continue the transposition of UN-GTR 2 into UN-Regulation 40, with the first meeting scheduled for 9 October 2026. The group exchanged information on maximum power determination for two-wheelers, battery electric vehicle range determination standardization using SAE J2982 and Chinese standard GB/T 24157-2017, and deterioration factors in GTR 23 on durability. Subsequent EPPR meetings and Task Force sessions are scheduled through June 2027.

Proposal for a task force to conduct discussions for drafting the regulation to incorporate the Euro 4-level requirements of UN GTR No. 2 into UN R40. Malaysia and Japan will serve as co-chairs. The Task Force shall review the Euro 4 level requirements and any relevant provisions of UN GTR No. 2 and assess their suitability for transposition into UN R40 under the 1958 Agreement framework. The Task Force shall develop draft regulatory text covering test procedures and test conditions, pollutant limit values and related technical parameters, reference fuels and associated testing requirements, administrative and type approval provisions, and transitional provisions and entry-into-force considerations. Target for submission of informal document for draft UN R40-03 is 96th GRPE scheduled in April 2027.

The agenda includes:

• Transposition of UN-GTR 2 into UN R40 based on WP.29/2026/24 02 series amendments,
• Feedback from the previous session consolidated in EPPR-74-09-Rev.2,
• Maximum power determination discussions referencing prior documentation,
• Battery electric vehicle range determination standardization including SAE J2982 procedures,
• Deterioration factors in GTR 23 durability using EPPR-56-04, EPPR-65-04Rev.1, and EPPR-65-05 analyses.

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.
