Report of the 100th EVE IWG session held October 13, 2026. The group discussed UN GTR 22 status and proposed amendments to UN Regulations Nos. 83 and 154 concerning usable battery energy (UBE) and State of Certified Energy (SOCE) values; UN GTR 21 amendments extending scope to fuel cell electric vehicles (FCEVs), replacing driver/accelerator command terminology, and reducing sampling frequency to 10 Hz, with target completion December 2027; and UN GTR 25 amendments addressing minimum performance requirements (MPRs), energy throughput, and Part C virtual distance verification. Japan proposed amendments to UN Regulation No. 177 for ICE power output references. The F&SC received a one-year mandate extension to continue validation activities and address outstanding issues on smart charging test procedures and key performance indicators.

Proposal to amend Annex 5, para. 5. to define Part C: Verification of reported assessment of virtual distance, amend para. 5.1. to specify the verification procedure including measurement of total discharge energy and approval by the responsible authority, insert new sub-paras. 5.1.1. through 5.1.5. to establish environmental temperature requirements, initial State of Charge setting, discharging test specifications, test termination conditions, and verification test procedures with Table 4 steps, and amend para. 5.2. to establish pass/fail criteria based on comparison of reported delta virtual distance to measured virtual distance with a 5 per cent threshold and statistical decision procedures using Table 5.

Proposal to amend para. 3.1.2. of Annex 5 to clarify the verification procedure for SOCR/SOCE monitors by specifying that electric range and UBE values shall be measured at the time of verification with related monitor values collected before and after the verification test procedure, that indicator values collected after the verification test procedure shall not be considered in Part A verification, and that measured SOCR and measured SOCE values shall be determined by dividing measured values for electric range and UBE by certified values for electric range and UBE respectively, expressed in per cent.

Report on the 95th GRPE session presenting progress updates for UN GTR No. 21 (Determination of Electrified Vehicle Power), UN GTR No. 22 (In-vehicle Battery Durability for Electrified Light-Duty Vehicles), and UN GTR No. 25 (In-vehicle Battery Durability for Electrified Heavy-Duty Vehicles). The IWG on EVE reported on Phase 4 objectives and amendments for GTR 21 and 22, with consideration targets of March 2028, and Phase 3 amendments for GTR 25 with consideration target of March 2027. Future work includes investigations into charging power curves, development of a new WP.29 resolution on DC Fast Charge Power Curve performance, and an inventory on harmonization of recharging capabilities.

Status update on Euro 7 implementation for light-duty and heavy-duty vehicles. For LDV (M₁, N₁), application begins 30 months after Euro 7 entry into force for new types (29 November 2026) and 42 months for all new vehicles (29 November 2027). For HDV (M₂, M₃, N₂, N₃, O₃, O₄), application begins 48 months after entry into force for new types (29 May 2028) and 60 months for all new vehicles (29 May 2029). Small Volume Manufacturers comply from 1 July 2030 (M₁, N₁) and 1 July 2031 (M₂, M₃, N₂, N₃). Brake emissions apply 1 January 2030 for LDV and 1 January 2030–1 January 2035 for HDV. Tyre abrasion (UN R186) applies 1 July 2028 for C1 class tyres, 1 April 2030 for C2 class, and 1 April 2032 for C3 class.

The report describes the final status of Amendment 2 to UN GTR No. 24 covering laboratory measurement of brake emissions, including hardware requirements (brake dynamometer, enclosure design, fixtures, temperature measurement, sampling tunnel and plane), the WLTP Brake cycle test procedure with quality checks and temperature specifications, cooling air conditioning specifications, cooling adjustment section procedures for different brake categories, bedding and emissions measurement sections, and PM mass concentration measurement methodology validated through an Inter-laboratory Study across multiple testing facilities.

The Task Force reviewed and approved regulatory amendments for ADS-equipped vehicles across multiple UN Regulations. Key decisions included adopting a simplified and consistent definition of ‘vehicle user’ for light-duty and heavy-duty vehicles, retaining original wording for warning signal transmission to ADS systems, and amending engine torque terminology under UN R49. Amendments were reviewed for UN R49, UN R83, UN R115, UN R154, UN R177, UN R179, and UN R180, with focus on consistency regarding ADS testing modes and an additional 25 kg mass allowance for vehicles of categories X and Y. The Task Force acknowledged that ADS operation may result in additional energy consumption not fully reflected in current testing procedures and agreed to seek GRPE guidance on possible future work.

Proposal to clarify applicable FCV test procedure, align run-in provisions with UN-R154, add SOC correction and modern hydrogen measurement provisions, correct inconsistencies, update hydrogen fuel specifications, and replace outdated UN GTR No. 15 reference in UN-R101 with UN-R154 for alternative road load determination.
