Reference Number: GRBP-83-32/Rev.1
Proposal to supersede document GRBP/2025/27 for a new UN Regulation on uniform provisions concerning the approval of tyres with regard to abrasion performance. The regulation establishes scope, definitions, application requirements, marking standards, approval procedures, and technical requirements for class C1 tyres. It excludes temporary-use spare tyres, competition tyres, ice grip tyres, studded tyres, and certain other tyre categories. Type approval is granted if candidate tyres meet abrasion performance limits measured by one of two methods: vehicle testing on public open roads or indoor drum testing. Abrasion index limits are defined for normal, snow, and special use tyres, with adjustments for specific tyre groups. Requirements include conformity of production verification, penalties for non-conformity, and transitional provisions establishing Stage 1 and Stage 2 implementation timelines with specified dates for mandatory approval.
Proposal to amend UN GTR No. 21 on determination of system power of hybrid electric vehicles and pure electric vehicles with more than one electric machine for propulsion. The amendment establishes reference points representing where mechanical power is first produced from energy storage systems, distinguishes between Test Procedure 1 (measuring electrical power and engine power) and Test Procedure 2 (measuring torque and speed at axles or wheel hubs), requires manufacturers to provide verifiable K factors representing conversion efficiencies, mandates five test repetitions with averaging of the last four, specifies measurement accuracies and frequencies, removes dynamometer roller measurement option for TP2 in favor of torque and speed sensors or hub dynamometer, adds system bench testing as alternative with manufacturer approval, and includes applicability guidelines determining which procedure applies to specific powertrain architectures.

Reference Number: GRBP-83-35
ETRTO presents a temporary conservative transfer function for tyre abrasion testing with a gain value of 1.5, designed to minimize drum inversion risk and reduce rejection risk while enabling coexistence of Indoor Drum Method and Outdoor Vehicle method at GRBP 83rd session. The transfer function, based on TA-40-2 data analysis, will be revised following a 2026 workplan before a more relevant solution in Supplement 1 to UNRxxx at GRBP 84th session.
Tyre abrasion: Positions on remaining open points in the draft UN Regulation
Reference Number: GRBP-83-37
ETRTO presents its position on remaining open points for C1 tyre abrasion limit settings, reminding positions from GRBP-82-24. Key points include: inclusion of two assessment methods; limit settings proposing approximately 23% market removal by Euro7 application timeline and additional 13.5% removal five years later; exclusion of C1 special use tyres representing 0.7% of EU market; retention of 0.1 allowance for Extra Load tyres and tyres with nominal aspect ratio 40 suitable for speeds 300 km/h representing 7.2% of market. ETRTO views this as a challenging compromise package respecting political expectations and industry effort.

Reference Number: GRBP-83-50/Rev.1
Proposal to establish a list of test facilities deemed equivalent pursuant to paragraph 12.8 of the draft UN Regulation on tyre abrasion. The list recognizes six foundational facilities that participated in the initial inter-facility campaign to develop abrasion limits for C1 tyres. The facilities are: DEKRA Test Center SA (France, circuit); IFV (Germany, circuit); Link Engineering Company GmbH (Germany, circuit); Bridgestone Corporation (Japan, indoor drum); Sumitomo Rubber Industries, LTD. (Japan, indoor drum); and The Yokohama Rubber Co., Ltd. (Japan, indoor drum). These facilities generated foundational data used to define abrasion limits and are deemed equivalent for equivalence procedures under Annex 4.
Tyre abrasion: Proposal to amend provisions for demonstrating test method equivalence
Reference Number: TA-46-02
The document establishes procedures for demonstrating equivalence between vehicle circuit and indoor drum test facilities. It defines requirements for selecting exercise tyres and participating facilities, establishing baseline values from multiple facilities, and comparing facility results against baselines. For indoor drum facilities, transfer functions mathematically relate drum results to vehicle results, either as generic (fixed coefficient) or specific (facility-determined coefficient). Facilities must meet statistical criteria including result deviation limits and root mean square deviation thresholds to demonstrate equivalence.

Paragraph 2.51. amended to read that the authority which has granted type approval may verify conformity control methods, with normal minimum frequency of verifications at least once every three years. Justification states special use tyres should be excluded as no limits will be established for them, and the three-year frequency aligns with Schedule 1 of the 1958 Agreement.
Tyre abrasion: Comments on compromise proposal for Annex 4
Reference Number: GRBP-83-52
ETRTO comments on EC/JRC compromise proposal for Annex 4 tyre abrasion. ETRTO proposes an ALI range minimum of 0.5 as feasible and consistent with statistical distribution in MA results, rejecting the 0.7 range as unrealistic. For Generic Transfer Function gain, ETRTO recommends retaining a = 1.38 rather than the revised a = 1.45, to minimize rejection of good vehicle test results. ETRTO requests TFTA ToR amendment to confirm these conditions by February 2027 based on TA-45-9.

Tyre abrasion: Position on the draft UN Regulation
Reference Number: GRBP-83-54
JATMA submitted this position on the draft UN Regulation for tyre abrasion at GRBP-83-54. JATMA requests adoption of the indoor drum test method under conditions equivalent to the vehicle test method for type approval. JATMA proposes that the Generic transfer function coefficient should be 1.14, calculated excluding tyre code 127 which exhibits significant variation. JATMA also proposes that the abrasion index range for tyres used in the Annex 4 procedure should be set between 0.4 and 0.5, and that no restrictions should be imposed on baseline test facilities when applying the Specific Transfer Function.
This status report documents the Tyre Abrasion Task Force’s progress toward finalizing a draft UN Regulation on tyre abrasion for C1 tyres, as presented to GRBP 83 Part II. The task force pursued three workstreams: data analysis to reduce method uncertainty and inversion risk, editorial improvements to increase clarity of the draft regulation, and development of a method equivalence solution. GRBP 83 Part I achieved consensus on limit values and introductory dates but could not reach consensus on equivalence procedures between convoy and drum methods. Six informal documents (GRBP-83-32-Rev.1, GRBP-83-48-Rev.1, GRBP-83-49, GRBP-83-50-Rev.1, GRBP-83-53, and GRBP-83-55) addressing equivalence methodology, drum specifications, and code of practice frequency were submitted for potential adoption at the extraordinary GRBP 83 Part II session.

EV/HFCV retrofit systems: Position on cyber security
Reference Number: EV/HFCV-08-02
RME views: Vehicles were on the road before UN R155 came into force. Retrofitting extends vehicle life in line with climate action and circular economy objectives. Retrofitters must be responsible only for components involved in the transformation and any parts they add or modify, not for original vehicle components. A risk management demonstration dossier limited to the transformed system must be included in transformation approval applications. If the origin vehicle is not R155-approved, retrofitters may provide the dossier without laboratory tests. If R155-approved, authorities decide on compliance, requiring laboratory tests if needed. Manufacturers’ data are not accessible to retrofitters. The application of cyber security provisions (i.e., UN R155 compliance) should be delayed by two years from the entry-into-force of the new regulation for the approval of EC/HFCV retrofit systems and revisions to UN R155 should also provide two-year transitional provisions before the application to the retrofit regulation.

Particle Measurement Programme: Agenda for the 56th (May 2026) session
Reference Number: PMP-56.3-01
The PMP webex meeting scheduled for 7 May 2026, 12:00-14:30 CET will review meeting minutes from 13.03.2026, provide an overview of amendments to Brakes GTR 24 and UN R179 covering layout and testing topics, vehicle limited speed, brake replacement parts, and electromechanical brakes, discuss GTR HD brakes, and address any other business.
PMP TF 3a Consolidation & Update of UNR179 & GTR24
Reference Number: PMP-56.3-02
PMP TF 3a is consolidating and updating UN R179 and GTR 24 through weekly web-meetings organized by JRC with 30+ participants. Over 50 topics have been identified and categorized by priority. Key issues include aligning Type Approval and Conformity of Production testing procedures, harmonizing cooling air adjustment requirements, clarifying vehicle c-factor calculations, adding definitions for light-duty vehicles exceeding 3.5 tonnes, and addressing test wheel load per GRPE-94-15e. The task force is preparing track changes versions and supporting documentation for major changes.
Task Force 4 addresses brake system development towards dry brakes, specifically electromechanical brakes. Current methods to determine friction brake torque available for hydraulic systems are not all applicable for dry systems. Task Force 4 targets defining a pressure-based equivalent method for electromechanical brake systems and reviewing document validity for electromechanical braking systems. Work Package B completed text document review with proposed changes due end of May 2026. Work Package A discusses two alternative approaches for c-factor calculation: clamping force based and recuperated energy based, with verification tests planned by end of June 2026.
Proposal to amend UN GTR 24 (Laboratory Measurement of Brake Emissions for Light-Duty Vehicles) by clarifying requirements for electromechanical brakes and dry brakes, modifying test procedures, updating definitions and technical specifications, revising cooling airflow adjustment methodologies, refining PM and PN measurement protocols, and adjusting calibration intervals and quality control procedures.
Tyre Abrasion: Agenda for the 48th (May 2026) session
Reference Number: TA-48-01/Rev.1
The agenda includes discussion of status of the work plan 2026 including the ITTAC proposal on tyre abrasion Convoy Method -Dual-Normalisation Framework (TA-45-08/Rev.1) and UTAC Tyre abrasion timeline Gantt (TA-46-03/Rev.1), development of the C1 tyre mileage potential metric and tread depth measurement prescription, and test method development status under C2 and C3.
ETRTO proposed three ways to estimate service life (TA-36-04): tread depth measurements, initial tread depth and abrasion index, and tread mass. JRC presented a service life index (TA-32-04) based on tread depth measurements and conducted a preliminary assessment of the second concept. Service life is estimated by linear extrapolation to 1.6 mm from tread measurements at test start and end. The Service life index is calculated as the ratio of candidate to reference tyre service life. Next steps include confirming the equation for service life via tyre characteristics and clarifying which tyre characteristics are needed.
PMP Task Force 3b held kick-off on 07.05.2026 to address vehicles with legal limited speed, vehicles unable to follow cycle trace, and vehicles with capped speed by OEM decision. Proposals include adaptation of UN R179 cycle and procedure for vehicles with legal limited speed at 90 kph, with same duration for acceleration, cruise, and deceleration events, same acceleration and deceleration rates, and speed capped when needed. Introduction of such vehicles into brake corner emission families and vehicle types requires methodology to calculate adapted cycle and procedure, including c-factor measurement as alternative to fixed c-factor, and adaptation of Annex 5 procedure.
At the 94th session of GRPE, CLEPA proposed a draft UN Regulation for approval of replacement brake parts. A dual pathway approach was proposed with two options depending on data availability: fully available data or minimal set of data with worst-case assumptions. PMP Task Force 3c was established to prepare a UN Regulation for approving replacement brake parts regarding particle emissions. The TF3c will define minimum information required under the simplified approach, assess variability within a family, and identify worst-case assumptions. CLEPA presented two approval concepts and requested support for Option A only. The next meeting is scheduled for 18 May 2026.
Particle Measurement Programme: Minutes of the 56th (May 2026) session
Reference Number: PMP-56.3-10
The 56th PMP session convened online on 7 May 2026 with approximately 70 participants. Meeting minutes from 13 March 2026 were accepted. PMP agreed on a joint neutral template for all task forces.

TF5 reported progress on GTR on HD brake particle emissions with test campaigns planned. The next meeting is expected end of June or beginning of July 2026.
Proposal to establish a new Mutual Resolution No. 5 (M.R.5) concerning Automotive Life Cycle Assessment (A-LCA) to provide an internationally harmonised methodology for determining carbon footprint of light-duty vehicles across all life cycle stages—material production, parts production and vehicle assembly, use, and end-of-life—using a level concept that distinguishes four levels of detail based on data availability and study purpose, applicable to different powertrain types and energy pathways, with provisions for energy modelling, recycling methodology, discrepancy and deterioration factors, maintenance assessment, and third-party verification requirements for Levels 3 and 4.
The A-LCAIWG will confirm open items and agree how to deal with nonagreed items by 12 May. A draft working document will be distributed by 12 June for review and refinement during the week of 6 July. The working document will be finalized by 17 June and distributed for final confirmation by 17 October, with presentation at the 95th GRPE session on 22 October.
Tyre abrasion: C2 tyres vehicle-method description
Reference Number: TA-48-02
TA-48-02 updates TA-47-02. C2 tyre abrasion rate index vehicle method uses a convoy of up to 4 vehicles with single tyres, GVW up to 3.5T, FWD, loaded 60%–74% of tyre nominal load with 50/50 front/rear distribution. Test distance is 10000 km at 80% nominal pressure. Reference tyres use 2 sets of test runs with C2 candidate SRTT and existing C1 SRTTs. 2025 testing in 235/65R16C and 205/65R16C sizes showed C2 tyres sensitivity to temperature similar to C1 tyres. 2026 plan repeats and extends 2025 testing to confirm reference tyres strategy, assess temperature sensitivity and pressure impact, and define validation plan.
Tyre abrasion: European heavy-duty vehicle and tyre market overview and status C3 test method development
Reference Number: TA-48-03
The document presents a European heavy-duty vehicle and tyre market overview and C3 test method development status. The C3 tyre market is complex and diversified, with applications including long haul, regional, on/off road, winter, and urban use. A test concept has been developed focusing on road usage with 22.5" tyres, using convoys of up to four vehicles with defined acceleration standards, road distribution of 60% motorway and 40% regional roads, and tests per axle comparing candidate tyres to reference tyres. Current activities include assessment of reference tyres strategy, temperature sensitivity evaluation, and confirmation of test parameters for heavy trucks in N3/O3 configuration, with tests reaching 30,000 to 45,000 kilometres.
Tyre abrasion: Is there a difference between 2 cars fitted with SRTT?
Reference Number: TA-48-05
DEKRA Test Center examined whether vehicles fitted with SRTT impact tyre abrasion rates. Tests DEKRA #104 and DEKRA #41 compared SRTT Summer as candidate against SRTT Winter as reference, with abrasion indices of 1.18 and 1.19 respectively, showing no vehicle impact. Tests DEKRA 8 and DEKRA 9 showed abrasion rates of 45.1 mg/km/T and 45.0 mg/km/T respectively with no difference despite different vehicles. A 2024 convoy test with two Golf vehicles fitted with identical SRTT Summer showed a difference of 1 gram cumulated weight loss after 7,962 km (0.07 mg/km/T). DEKRA concludes the impact on abrasion level of the reference vehicle using SRTT is low or very low.
Existing C1 tyre-abrasion test methods cannot be directly applied to C3 tyres because vehicles equipped with C3 tyres are used differently. Japan is developing a vehicle test method using WHVC mode and plans to develop a drum test method based on test conditions and results. Test conditions will convert vehicle driving conditions representing the world into indoor drum test settings. C2 test method uses driving mode based on WLTP with fixed test load details, with verification tests using reference tyres. For C3, driving modes and test conditions are under preliminary investigation, with verification tests to be planned.
Status of regulation screening for applicability to ADS vehicles
Reference Number: GRSP-TF-AVRS-26-05
GRBP, GRE, GRPE, GRSG, GRSP, and GRVA are ready with working documents on non-ADS regulation amendments. TF AVRS is working on ADS marker lamps. UNECE published 93 amendment proposals regarding ADS fitness and ADSUNR and GTR for the 199th session of WP.29 in June 2026. UN R168.00 is tabled for the 200th session of WP.29. UN R154 former series is postponed to GRPE-95 in October 2026. Y category passive safety regulation is planned for GRSP-80 in December 2026.
The IWG on PTI Provisions for PTI works on whole-life compliance, testing ADAS/ADS at Periodic Technical Inspection, ePTI provisions, driverless vehicle inspection, and anti-tampering measures across 2025–2027. Provisions for PTI exist in at least 20 UN Regulations as of 8 April 2026, though PTI experts deem some insufficient and additional provisions may be needed. The proposed update procedure requires the IWG to generate a current provisions list, present needs to WP.29, develop proposals for the first 2–3 UN Regulations, defend each proposal in relevant GRs, and transmit outcomes to WP.29 for decision.
EV/HFCV Retrofit Systems: Minutes of the 8th (April 2026) session
Reference Number: EV/HFCV-08-07
The Informal Working Group on EV/HFCV Retrofit Systems held its eighth meeting on 21 April 2026. The group discussed cybersecurity principles, requiring retrofitted vehicles not to reduce safety or cybersecurity performance compared with UN R155 requirements, with differentiated approaches for base vehicles approved or not approved to UN R155. Braking compliance, EMC testing references, and UN draft regulation changes including renaming to “vehicles intended to be transformed into pure electric vehicles” and introducing Electric Powertrain Retrofit Systems definitions were addressed. PTI-related aspects and the need for written contributions were highlighted before providing the draft regulation to GRPE in October.

The amendments ensure text robustness and alignment between GTR 22 and UN R154/04. The monitor was copied from Part A families and is not mentioned in Part C. The Battery cell characteristic includes the REESS as part of the Family concept.
GTR 22 proposes introducing a State of Certified Energy (SOCE) Readiness Status to determine when sufficient enabling conditions exist for accurate battery State of Health calculations. Manufacturers shall make SOCE values easily available to vehicle owners via dashboard, infotainment, or mobile application and provide procedures for owners to achieve recent updates. GTR 22 shall include mandatory parameters: State of Certified Energy Readiness Status, Energy Storage System Recent Depth of Discharge Counter, and Preconditions for Recent Battery Capacity Update, removing quantitative specifics dependent on energy storage chemistry and time duration references from existing annexes.
Electrification of the Norwegian LDV and HDV sector
Reference Number: EVE-97-05
The document presents Norway’s electrification progress for light duty vehicles (LDVs) and heavy duty vehicles (HDVs). Norway has 994,000 electric LDVs and 5,300 electric HDVs from a total fleet of 3.4 million LDVs and 73,000 HDVs. In April 2026, EV market share reached 98.6 percent with 107 municipalities achieving 100 percent market share. The document reports EVs represent 2-7 percent of registered vehicle fires, with fossil fuelled vehicles accounting for up to 90 percent. Research findings indicate battery degradation is driven by operating conditions, with cold climate introducing dual effects and battery management systems being key durability drivers.
The presentation reports results from performance-based models for electric passenger vehicles and electric vans, analyzing capacity retention and capacity fade at 5, 8, and 10 years and at 100,000 km, 160,000 km, and 200,000 km driving distances. Results show capacity retention exceeding 60 per cent at 10 years and 200,000 km for vans with Li-Ion NCM-LMO (2015) battery technology, and exceeding 65 per cent for battery electric vehicles under the same conditions.
Next step of GTR No. 25: HDV Minimum Performance Requirements, lifetime and metric revision
Reference Number: EVE-97-07
UN GTR No. 25 addresses minimum performance requirements, lifetime requirements, and metrics for heavy-duty vehicles. Lifetime requirements are 12 years and 700,000 km or 15 years and 875,000 km for Category 1-2 vehicles exceeding 7.5 tonnes and Category 2 vehicles exceeding 16 tonnes. An optional annex proposes different metrics including years, kilometres whichever comes first, and energy throughput in monitoring. Capacity retention requirements for N₃ vehicles exceeding 16 tonnes are specified at 12 years and 700,000 km and at 15 years and 875,000 km.
EV and Hydrogen Fuel-Cell Vehicle Retrofits: Comments on GRVA-25-07
Reference Number: GRVA-25-41
OICA-CLEPA-EME comments on German proposal GRVA-25-07 to require the approval authority granting UN R155 or UN R156 type approvals to use CSMS or SUMS certificates signed by the same approval authority. OICA-CLEPA-EME identify that CSMS and SUMS are Management Systems covering entire manufacturer organizations, and mandating the same approval authority for Management Systems certificates and approvals will have significant consequences for original equipment manufacturers typically using multiple approval authorities in homologation. The submission proposes keeping text unchanged to allow different approval authorities for Management Systems certificates and type approval based on voluntary acceptance, implementing wording on information exchange if different approval authorities are involved, and establishing a horizontal approach for Management Systems with mutual recognition aspects considered.
Proposal to amend Amendment 2 to UN GTR No. 22: Modify para. 5.2. to define virtual distance calculation and add requirements for reporting virtual distance by vehicles with V2X functionality or Category 2 vehicles used for non-traction purposes, add new para. 5.2.1. specifying virtual distance determination, add para. 6.1.3. defining Part C family criteria for virtual distance verification, add para. 6.5. establishing Part C verification procedure for reported virtual distance with test conditions including environmental temperature 23°C ± 5°C, initial battery SOC according to normal charging procedure, discharge testing at highest available power, test duration of 50 km virtual distance or 2 hours, and pass/fail criteria requiring reported virtual distance not more than 5 per cent higher than measured virtual distance, add para. 6.5.2.1. with statistical decision chart for Part C pass/fail determination based on cumulative sample size and failed result counts, revise para. 6.1.4. to add family identifier format for virtual distance families, add para. 52.a. through 52.e. in the Statement of Technical Rationale documenting Phase 3 developments including family criteria for Part C verification, boundary conditions for virtual distance verification test with environmental temperature requirements and discharge test options based on kilometres or hours, OVC-HEVUBE correction in Annex 3, and additional regional regulation requirements in Annex 2, and add flow chart Figure 3 for Part C verification process.
