The draft amendments concern: (i) harmonization of the structure of the Rule No. 1 with Rule No. 2 (Roadworthiness), (ii) introduction of vehicle categories M1 and N1 and trailer categories O2, O3 and O4, and (iii) introduction of inspection methods, defect assessment and current state of practices.

8. Prior to the consideration at its June 2013 session, the World Forum asked GRPE to provide technical input to the report on diesel exhaust emissions, taking into account the incorporation of the comments and the inclusion of recommendations in the latest draft.

9. WP.29 adopted the Environmentally Friendly Vehicles (EFV) summary report and decided to freeze the activities of the EFV informal working group and the EFV task force group.

10. WP.29 acknowledged the nomination of the expert from Spain as the GRPE Ambassador for issues concerning the International Whole Vehicle Type Approval (IWVTA) and considered a first draft of the revised 1958 Agreement (WP.29-159-19). A final draft is expected in November 2013, when the submission of a first draft of the Regulation No. 0 (containing requirements for the whole vehicle type approval) is also scheduled.

11. Following an update on the status of the work on the Worldwide harmonized Light vehicles Test Procedures (WLTP), WP.29 confirmed to the GRPE Chair its availability to provide guidance at its June 2013 session, in case of remaining issues.

12. The updated terms of reference of the informal working group on Electric Vehicles and the Environment (EVE), adopted by GRPE in its last session (January 2013), will be considered in the June 2013 of WP.29.

3. Light vehicles
3. (a) Worldwide harmonized Light vehicles Test Procedures (WLTP)

13. The secretary of the WLTP informal subgroup on the Development of the Harmonized driving Cycle (DHC) introduced GRPE-66-34, containing the report on the progress made since January 2013. Having stated that almost all open issues were successfully closed, he reported that DHC successfully developed the harmonized test cycles, including the downscale procedure (even if the downscale calculation formula requires finalization after correcting minor issues), the mode construction, and the gear shift prescription (notwithstanding continued work for its improvement). A draft final report on the development of the Worldwide harmonized Light vehicles Test Cycle (WLTC) is already available and will be included in the Technical Report.

14. Responding to a question by the expert from Italy, the expert from the EC clarified work for regional weighting factors is ongoing in the European Union. He specified that Contracting Parties do not need to apply regional weighting factors for the harmonized cycle, even if there is a possibility to apply regional weighting factors if this is justified by regional driving characteristics. Having mentioned that the application of regional weighting factors can be further discussed, he added that this is not envisaged at the moment and he agreed with the GRPE recommendation to clarify this issue also in Part A of the UN GTR text.

15. The Chair of the informal subgroup on the Development of the Test Procedure (DTP) reported on the work status of the subgroup (GRPE-66-36). He stated that there are a number of remaining open issues that need to be addressed. According to the mandate documents (ECE/TRANS/WP.29/AC.3/26 and Add.1) three phases are included in the WLTP terms of reference: phase I, concerning the development of the UN GTR (test cycle and test procedure); phase II, concerning on-board diagnostics (OBD) and additional tests (e.g. on pollutants other than CO, NOX, hydrocarbons and particulate matter); and phase III, about reference fuels and performance requirements. Phase I can be further divided in two stages, with the aim to continue work on still open issues and to improve and correct the text of the GTR based on validation and experience. The issues that are foreseen to be solved in phase I, stage 1, include: (i) Rechargeable electric energy storage system Charge Balance (RCB) correction; (ii) the warm-up procedure for the road load and dynamometer setting; (iii) the speed trace violation, concerning deviations from the test cycle beyond the prescribed tolerances; (iv) the definition of the predominant mode for vehicles with multimode gearboxes; and (v) the temperature correction for regional representative conditions for the CO2 emission determination. Other issues could be finalized in phase I, stage 1, or eventually (in a fall back solution) postponed to stage 2: (i) the table of running resistances, concerning default values to be used in the dynamometer settings if the road load cannot be determined; (ii) the ambient temperature for coast-down (the latest discussions were settling on 5 to 40°C ± 5°C); and (iii) utility factors on electric vehicles. If an agreement is not reached in phase 1, stage 1, the issues will need to be defined regionally. Concluding his intervention of the status of the DTP subgroup, the DTP Chair reported that, even if the coast down and wheel torque methods are agreed, the wind tunnel and the comparison of road load determination methods are likely to be addressed in phase I, stage 2.

WP.29/AC.3/26/Add.1 | Addendum to the proposal to develop a new GTR on worldwide harmonized light vehicle test procedures

16. Reporting on the development of the WLTP regulatory text, the DTP Chair explained that a draft UN GTR was uploaded to the UNECE website prior to the GRPE session (GRPE-66-02). He recalled that there are a number of major open drafting points and outlined the schedule of forthcoming meetings and milestones for the completion of the drafting work. He specified that: (i) the analysis of results emerging from the GRPE discussion will be completed before end of June 2013; (ii) a meeting for the solution of outstanding issues is foreseen for the end of June 2013 in Brussels; (iii) the draft UN GTR will be circulated to WLTP members in early July 2013; (iv) a drafting group meeting will take place between 19 July 2013 and the last week of July 2013; (v) the finalisation of the draft of the UN GTR will be completed before the submission deadline for the working documents of the November 2013 session of GRPE. WP.29 is then expected to consider the text in March 2014. On the content of the regulatory text, he confirmed that the UN GTR will include an explanatory section (part A). A technical report on the UN GTR will be available as an informal document for the November 2013 session of GRPE.

17. The DTP Chair and the expert from the EC agreed that part A will be drafted by the EC, while the technical report will be delivered by an expert contracted in the framework of the DTP activities. Both these documents will be circulated to Contracting Parties for their inputs. The expert from the EC mentioned that the text of part A will be finalized by the end of July 2013. Given the involvement of OICA for the WLTP development, the expert from OICA informed GRPE about his availability and interest to contribute the preparation of the text of part A and the technical report.

18. Having recalled the mandate documents (ECE/TRANS/WP.29/AC.3/26 and Add.1) and the information on the status of the DTP work, the GRPE Chair concluded indicating that the adoption of the UN GTR will conclude the first stage of phase I, while the second stage will result in an amendment of the UN GTR.

WP.29/AC.3/26/Add.1 | Addendum to the proposal to develop a new GTR on worldwide harmonized light vehicle test procedures

19. GRPE agreed that the work plan shall include the adoption of the UN GTR in the extraordinary GRPE session of November 2013. The start of the work on the first UN GTR amendment shall take place right after the UN GTR adoption and after the approval, by AC3, of a request by the co-sponsors for a mandate to develop it under the WLTP informal working group. GRPE stressed the need to define, in part A of the regulatory text, which parts of the work will be tackled in stage 2 of phase I, and agreed that: (i) part A shall be distributed at the end of July 2013 and included in the working document submitted in August 2013; and (ii) the technical report shall be submitted, as an informal document, in November 2013. In case of adoption by GRPE, both these documents can then be considered as working documents by WP.29 in March 2014.

3. (b) Mobile Air-Conditioning Test Procedure (MACTP)

20. The Chair of the informal group on MACTP reported that the MACTP group did not meet before the GRPE proper session and requested a meeting in conjunction with the next ordinary GRPE session, in January 2014. The expert from the EC added that the first round of pilot testing was successfully finalized, notwithstanding some issues related with the recirculation strategy of one of the vehicles being tested and the need to repeat the test with manual recirculation settings.

21. GRPE acknowledged the work progress.

3. (c) UN Regulations Nos. 68, 83, 101, and 103

22. Having introduced ECE/TRANS/WP.29/GRPE/2013/11, containing a proposal for the transposition of the Euro 6 legislation on the exhaust emissions of pollutants into the UN Regulation No. 83 (as explained also in GRPE-66-22), the expert from the EC explained that further amendments to the Euro 6 regulations are expected to be agreed upon in July 2013. The original plan was to include these amendments in UN Regulation No. 83 with the adoption of ECE/TRANS/WP.29/GRPE/2013/11 (as amended by GRPE-66-04-Rev.1, concerning the choice of tyres) during the current GRPE session, and to submit the changes that will be agreed upon in July 2013 to the January 2014 session of GRPE.

GRPE-66-04/Rev.1 | Proposal for an amendment to the 07 series of amendments to Regulation No. 83 Proposal to amend document GRPE/2013/11 by expanding upon the tire selection process to focus on rolling resistance.
GRPE-66-22 | Transposition of Euro 6 into UN R83/Proposed amendments to R101 and R103 Document GRPE/2013/11 presents the EC proposal to integrate Euro 6 provisions into UN R83. This presentation covers the work that went into this proposal and its implications for UN R101 and R103.
GRPE/2013/11 | Proposal for the 07 series of amendments to Regulation No. 83 Text from the European Commission to align UN R83 with EU Regulation (EC) Nos. 715/2007, 692/2008, 566/2011, 459/2012 and 630/2012, proposed as a consolidated series of amendments.

23. The expert from OICA suggested postponing the approval of ECE/TRANS/WP.29/GRPE/2013/11 (and related modifications, including those contained in GRPE-66-32, concerning requirements for daytime running lamps and clerical errors) due to the potential confusion caused by the forthcoming amendments to the Euro 6 regulatory texts.

24. The experts from Germany and the Netherlands supported the approach suggested by OICA. The expert from Germany also stated that the Euro 6 requirements concerning vehicles using a mixture of hydrogen and natural gas as fuel shall follow the introduction of safety-related requirements. The expert from the EC clarified that, in the European Union, setting the emission requirements does not lead to the possibility to type approve the whole vehicle, since this will only be feasible once the safety provisions are defined and adopted. Following the warning of the expert from OICA about the absence of whole vehicle type approval requirements in the UN regulatory framework, he added that, if deemed necessary, the introduction of emission requirements for vehicles using a mixture of hydrogen and natural gas as fuel in UN Regulation No. 83 could be reconsidered.

25. GRPE agreed that all modifications introduced in the current session of GRPE to ECE/TRANS/WP.29/GRPE/2013/11, as well as those emerging from the discussion scheduled for July 2013 in the European Union framework and other eventual changes, shall be incorporated in a new working document that will be submitted for the January 2014 session of GRPE.

GRPE-66-32 | Proposal for an amendment to the 07 series of amendments to Regulation No. 83 The purpose of this proposal is to modify the content of document GRPE/2013/11 (proposal for the 07 series of amendments to Regulation No. 83 by the European Commission) in order to avoid misinterpretation for practical application and implementation of the regulation.
GRPE/2013/11 | Proposal for the 07 series of amendments to Regulation No. 83 Text from the European Commission to align UN R83 with EU Regulation (EC) Nos. 715/2007, 692/2008, 566/2011, 459/2012 and 630/2012, proposed as a consolidated series of amendments.

26. The expert from OICA introduced GRPE-66-16, containing a proposal to amend the 06 series of amendments to UN Regulation No. 83 in order to align the emission requirements for social needs vehicles (currently based on M vehicles) with those enforced in the European Union (also contemplating N1, class 3 limits).

27. GRPE requested the secretariat to distribute GRPE-66-16 as an official document for consideration at the GRPE session of January 2014.

GRPE-66-16 | Proposal for amendments to the 06 series of amendments to Regulation No. 83 Proposal to align the 06 series of amendments to UN R83 with the full EU requirements for “social needs” vehicles. In the 06 series of amendments, emission compliance for social needs vehicles is based on M limits only, while in the EU, these vehicles can comply with N1 class 3 limits.

28. Presenting GRPE-66-22, the expert from the EC explained that the implementation of the Euro 6 legislation also justifies the proposals (contained in ECE/TRANS/WP.29/GRPE/2013/9 and ECE/TRANS/WP.29/GRPE/2013/10, respectively) to amend UN Regulations Nos. 101 and 103.

29. The expert from OICA introduced GRPE-66-17, explaining that it contains modifications to ECE/TRANS/WP.29/GRPE/2013/9 and additional amendments to the 01 series of amendments to UN Regulation No. 101 regarding the requirement for daytime running lamps and the fuel consumption of fuel cell vehicles.

30. GRPE adopted ECE/TRANS/WP.29/GRPE/2013/9, as amended by GRPE-66-17, and ECE/TRANS/WP.29/GRPE/2013/10, not amended. GRPE requested the secretariat to submit the adopted proposals to WP.29 and AC.1, for consideration at their November 2013 sessions, respectively as Supplement 3 to the 01 series of amendments to Regulation No. 101 and Supplement 4 to the 00 series of amendments to Regulation No. 103.

GRPE-66-17 | Consolidated proposal for amendments to draft Supplement 3 to the 01 series of amendments to Regulation No. 101 Proposed amendments to document GRPE/2013/9 regarding daylight running lamps and hydrogen balance in internal combustion versus fuel-cell vehicles.
GRPE-66-22 | Transposition of Euro 6 into UN R83/Proposed amendments to R101 and R103 Document GRPE/2013/11 presents the EC proposal to integrate Euro 6 provisions into UN R83. This presentation covers the work that went into this proposal and its implications for UN R101 and R103.
GRPE/2013/10 | Proposal for Supplement 4 to the 00 series of amendments to Regulation No. 103 Text from the European Commission to align the requirements of UN R103 with those of EU Regulation (EC) Nos. 459/2012 and 630/2012.
GRPE/2013/9 | Proposal for Supplement 3 to the 01 series of amendments to Regulation No. 101 Text from the European Commission to align the requirements of UN R101 with those of EU Regulation (EC) Nos. 459/2012 and 630/2012.
4. Heavy-duty vehicles
4. (a) Heavy Duty Hybrids (HDH)

31. The secretary of the HDH group introduced GRPE-66-23 and GRPE-66-24, containing information on the HDH work progress. He summarized the thirteenth and fourteenth group meetings, underlining the decision to include a new annex in UN GTR No. 4, amending it. Having explained the status of validation test programmes, he required further input from Contracting Parties, by October 2013, on the assessment of chassis dynamometer and power-pack testing. He acknowledged that the Environmental Protection Agency of the USA requested to include powertrain testing and verification in the UN GTR and expressed the interest to take part in the second validation test programme. A drafting group for the UN GTR has been established, although the nomination of a technical secretary is still outstanding. A draft will be submitted to the next ordinary GRPE session, in January 2014, when a final report will also be submitted. The official submission of the text amending UN GTR No. 4 is expected for June 2014.

GRPE-66-23 | Progress report of the HDH informal group to GRPE
GRPE-66-24 | Status report of the informal group on Heavy Duty Hybrid vehicle emissions

32. Focusing on the issue of CO2 emission measurement (which is part of the HDH mandate), and having considered that Contracting Parties have their own regional heavy duty CO2 regulations in place, he reported that the informal working group will develop a procedure for CO2 determination in a way that will allow its use as an input for the regional CO2 regulations, if needed. GRPE agreed with the approach outlined by the HDH Chair.

33. Following a request from the expert from Korea on the status of the CO2 emission regulation on heavy duty vehicles in the European Union, GRPE invited the expert from the EC to provide an update in the next ordinary GRPE session, in January 2014.

4. (b) Retrofit Emissions Control devices (REC)

34. Following an overview on the work of the REC group (GRPE-66-42), the Chair of the REC group illustrated ECE/TRANS/WP.29/GRPE/2013/6, a proposal for a new UN Regulation on REC, as well as: (i) GRPE-66-28, superseding GRPE-66-06 and modifying ECE/TRANS/WP.29/GRPE/2013/6 to introduce limit values and to include a set of flow charts in its Annex 8; and (ii) a draft proposal for the 01 series of amendments to the UN Regulation on REC (GRPE-66-07). These texts aim at facilitating the improvement of the ambient air quality via the reduction of the emissions of particulate matter and/or NOX. They address the emissions of NO2 via four classes of systems. The only outstanding issue for the 01 series of amendments concerns the NO2 emission requirements of traps that allow for a restricted increase of the direct emissions of NO2 (GRPE-66-08).

35. GRPE adopted ECE/TRANS/WP.29/GRPE/2013/6, as amended by GRPE-66-28, and requested the secretariat to submit the resulting proposal to WP.29 and AC.1, for consideration at their November 2013 sessions.

36. GRPE also requested the REC informal group to submit an updated version of the first amendment to the UN Regulation on REC (GRPE-66-07), reflecting the updates emerging from further discussions, so that the secretariat can prepare an official document for the GRPE session of January 2014.

4. (c) UN Regulation No. 49

37. The Chair of the informal group on Gaseous Fuelled Vehicles (GFV) introduced: (i) ECE/TRANS/WP.29/GRPE/2013/7, a proposal to amend the 05 series of amendments of UN Regulation No. 49 to extend the Euro V pollutant emission requirements to dual-fuel heavy duty engines and vehicles; and (ii) GRPE-66-25 (presented concisely in GRPE-66-39), a revision of the calculation methods also in use for the Euro VI dual-fuel engines, an update of hydrocarbon emission limits and some editorial modifications.

GRPE-66-25 | Revisions to Proposal for Supplement 6 to the 05 series of amendments to Regulation No. 49 Document GRPE/2013/7 was prepared to modify the 05 series of amendments of UN R49 (Euro V) in order to extend the pollutant emission requirements to dual-fuel heavy duty engines and vehicles. Per agreement with GRPE, this document proposes amendments to the 05 series based on the latest GFV work.

GRPE/2013/7 | Proposal for Supplement 6 to the 05 series of amendments to Regulation No. 49 Text prepared by the Chair of the Gaseous Fuelled Vehicles informal group–Heavy Duty Dual Fuel task force to introduce modifications to the 05 series of amendments of UN R49 (Euro V) in order to extend the pollutant emission requirements to dual-fuel heavy duty engines and vehicles.

38. The expert from the EC introduced ECE/TRANS/WP.29/GRPE/2013/8 and GRPE-66-10, containing modifications to the 06 series of amendments of UN Regulation No. 49 that aim to reduce the risks of misinterpretations of the regulatory text.

GRPE-66-10 | Proposal to change document GRPE/2013/8 and for new amendments to the 06 series of amendments to Regulation No. 49 Text prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.
GRPE/2013/8 | Proposal for Supplement 2 to the 06 series of amendments to Regulation No. 49 Text prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.

39. The expert from OICA presented GRPE-66-35-Rev.1, introducing the possibility to temporarily disable the OBD system for very low temperatures (first suggesting -18°C as a threshold, and later agreeing to use -22°C), arguing that only a fraction of vehicle km are run in these conditions and that the accuracy of the OBD devices is hampered at very low temperatures. Notwithstanding the need to ensure that the regulation of pollutant emission needs to be enforced also in the coldest regions and cities, the expert from Sweden accepted the proposal with a -22°C threshold. The expert from Norway supported the Swedish statement. The expert from the EC also supported the Swedish position, underlining that the deactivation shall be limited to the period of time during which the temperatures remain below the deactivation threshold.

GRPE-66-35/Rev.1 | Updated proposal to revise the 06 series of amendments to UN Regulation No. 49 Revised proposal to introduce an amendment to documents GRPE/2013/8 and GRPE-66-10 that would permit the manufacturer to request a temporary disablement of OBD monitors at low ambient temperature in the same manner as permitted at high ambient temperatures (above 35°C).

40. GRPE adopted ECE/TRANS/WP.29/GRPE/2013/7, as amended by GRPE-66-25, and ECE/TRANS/WP.29/GRPE/2013/8, as amended by GRPE-66-10 and GRPE-66-35-Rev.1. GRPE requested the secretariat to submit the resulting proposals to WP.29 and AC.1, for consideration at their November 2013 sessions, respectively as Supplement 6 to the 05 series of amendments to Regulation No. 49 and Supplement 2 to the 06 series of amendments to Regulation No. 49.

GRPE-66-10 | Proposal to change document GRPE/2013/8 and for new amendments to the 06 series of amendments to Regulation No. 49 Text prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.

47. Building on the presentation contained in GRPE-66-21-Rev.1, the PMP Chair summarized a proposal containing the terms of reference for the activities of the group (GRPE-66-30) and presented an overview of the related work programme. He explained that the scope of the terms of reference was intentionally kept as wide as possible (for example, non-exhaust particle emissions were also included) while the proposed work programme was limited to the items that were deemed to have the highest priority. The mandate for the work of the group on Particle Measurement Programme should be completed by June 2017. He added that addressing emerging issues such as the development and validation of new test procedures (such as particle number measurement systems compatible with Portable Emission Measurement Systems (PEMS)) and the consideration of issues like tyre/brake wear would require an extension of it.

48. The expert from India asked about the possibility to consider engines running on gaseous and blended fuels. The PMP Chair clarified that emissions from all engines types are already within the PMP group scope. Replying to a second question, on the possibility to analyse the particle nature and their danger for health, the PMP Chair explained that tackling these tasks would require not only specific equipment and expertise, but would also involve significant scientific challenges. Responding to comments and questions by the Russian Federation and CLEPA on tyre and brake wear, he confirmed that, even if these subjects were within the PMP scope, the current activities could concentrate mainly on early steps like a literature review.

49. GRPE acknowledged the work progress and approved the updated PMP terms of reference, as reproduced in Annex V, confirming the broad definition of the scope and agreeing with the priorities proposed by the PMP Chair, understanding that work cannot be conducted, at the same time, on all the issues.
