Proposal to correct an error found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and a cross reference in both the 06 and 07 series of amendments to UN Regulation No. 83.

Proposal to correct an error found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and a cross reference in both the 06 and 07 series of amendments to UN Regulation No. 83.

Proposal to extend the option from the 06 and 07 to the 05 series of amendments allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP).

Proposal aims at permitting the use of the latest reference fuels for evaporative emissions approval of vehicles

63. The Chair introduced GRPE-82-06-Rev.1 as the revised GRPE priority list including the latest progress made during this session. In particular, the Chair congratulated GRPE and all the stakeholders involved for the early delivery of the 07 series of amendments to UN Regulation No. 49. GRPE agreed to provide a clean version of GRPE-82-06-Rev.1 to WP.29/AC.2, when requested.

64. The representative from OICA wondered if hydrogen propulsion for heavy duty applications (whether using fuel cells or internal combustion engines) was to be included in the list of priorities with hydrogen likely to play a role in the future of transportation energy supply. He added a performance standard might be needed soon.

65. The Chair agreed that there are numerous white spots in heavy duty alternative powertrain types legislation on topics related to energy consumption and emissions. The representative from the Netherlands for example raised the quickly-emerging need for a procedure to determine range of battery electric heavy duty vehicles for eligibility criteria for financial subsidies decided by some governments. The representative from OICA also highlighted power determination procedures could be needed as powertrain concepts often differs from the existing ones.

66. The representative from EC proposed to organize a dedicated workshop on upcoming legislative needs for future heavy duty powertrains. The representative from OICA supported the idea and stood ready to co-organize such workshop with the assistance and support from the secretariat.

67. GRPE welcomed the initiative and agreed to organize such workshop as part of the next GRPE session in June 2021.

68. The representative from OICA introduced GRPE-82-16 on potential issues that might arise on the applicability and interlinkages between UN Regulations Nos. 83, 154 and [XXX] on RDE. The representative from EC thanked OICA for raising the issue and reiterated their intention to address the issues and how to deal with in-service conformity test in the various documents. She welcomed and encouraged the implication and assistance from all stakeholders to find a clever way to propose a solution to GRPE by the next session of GRPE.

69. The representative from Australia introduced GRPE-82-13 on the consultation process on-going in the country for the future emission legislation for light and heavy vehicles. The representative from EC required some information about the consideration to propose the latest 07 series of amendment to UN Regulation No. 49 (instead of the 06) for the future heavy vehicles’ legislation. The representative from Australia clarified the 06 series of amendment to UN Regulation No. 49 was the latest available when the proposal was drafted and amending this (upon decision from transport minister) would require starting a whole new process.

70. The representative from EC asked whether feedback to the consultation was expected from GRPE and its stakeholders. The representative from Australia said the consultation was primarily aimed at domestic stakeholders, and the he would be thankful to receive feedback from international stakeholders too.

71. The representative from OICA recalled that Australia was not a contracting party to UN Regulation No. 83 and asked if this was expected to change if Australia was to adopt UN Regulation No. 83 as part of its emission legislation. The representative from Australia said that Australia would in principle become a contracting party to UN Regulation No. 83 if adopted as part of this legislative process.

Proposal to clarify that the E10 reference fuel may still be used at the worst case for the Type IV test.

16. The representative from OICA introduced GRPE-82-08 proposing to amend the 05 and 06 series of amendments to UN Regulation No. 83 with respect to fuel specification alternatives for Type IV tests. The Chair of the IWG on Particle Measurement Programme (PMP) supported the proposal and agreed that testing with E10 fuel indeed represented a worst case scenario. The representative from OICA agreed and intended to prepare a working document for the next session of GRPE.

Proposal addressing the conversion of NEDC road load to WLTP road load in cases where the former has already been determined.

15. The representative from OICA introduced GRPE-82-07 proposing to amend the 06 and 07 series of amendments to UN Regulation No. 83 regarding equivalencies with respect to road load coefficients determination. The representative from Spain asked whether the sub paragraph (2) could be rephrased and clarified. The representative from OICA agreed and intended to prepare a working document for the next session of GRPE in June 2021.

Proposal to correct an error found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and a cross reference in both the 06 and 07 series of amendments to UN Regulation No. 83.

9. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/3 and ECE/TRANS/WP.29/GRPE/2021/5 correcting errors in the 06 and 07 series of amendments to UN Regulation No. 83. GRPE endorsed the proposals to amend the 06 and 07 series of amendments to UN Regulation No. 83.

10. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/3 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 16 to the 06 series of amendments to UN Regulation No. 83.

11. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/3 and ECE/TRANS/WP.29/GRPE/2021/5 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 13 to the 07 series of amendments to UN Regulation No. 83.

Proposal to extend the option from the 06 and 07 to the 05 series of amendments allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP).

6. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/2 extending the existing option included in the 06 and 07 into the 05 series of amendments to UN Regulation No. 83 allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP). The representative from Australia raised the point that the modifications made in the 06 and 07 series referred to UN Regulation No. 154 without specifying the level nor the series of amendments that apply, potentially risking the ability to approve vehicles that have a maximum speed below 130 km/h. GRPE noted that when NEDC road loads are calculated from WLTP road loads for use in UN Regulations Nos. 83 or 101, the maximum speed of the derivation tests must be sufficient for both the NEDC and for the specific vehicle.

7. The representatives from the Netherlands and CITA supported the proposal. GRPE endorsed the proposal to amend the 05 series of amendments to UN Regulation No. 83.

8. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/2 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 14 to the 05 series of amendments to UN Regulation No. 83.

Proposal to correct an editorial error of exhaust after-treatment system monitoring requirement.

9. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/3 and ECE/TRANS/WP.29/GRPE/2021/5 correcting errors in the 06 and 07 series of amendments to UN Regulation No. 83. GRPE endorsed the proposals to amend the 06 and 07 series of amendments to UN Regulation No. 83.

10. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/3 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 16 to the 06 series of amendments to UN Regulation No. 83.

11. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/3 and ECE/TRANS/WP.29/GRPE/2021/5 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 13 to the 07 series of amendments to UN Regulation No. 83.
