9. The expert from EC introduced ECE/TRANS/WP.29/GRPE/2016/4 aimed at correcting the calculation of the vehicle coast down resistance to progress force in the 07 series of amendments to Regulation No. 83.

10. The expert from OICA drew the attention to the confusion and administrative burden that could be created by the proposal if requirements were not aligned between the 06 and 07 series of amendments to Regulation No. 83, as well as with Regulation No. 101. He expressed his concern on the possible impact this may have on the CO2 emissions type approval value and, thus, on the correlation program between WLTP and the New European Driving Cycle (NEDC). He suggested considering amendments to the 06 and 07 series of amendments to Regulation No. 83 and to Regulation No. 101 as an entire package at the next GRPE session.

11. The Chair of GRPE suggested adopting the proposal not only for the 07 series but also for the 06 series of amendments to Regulation No. 83 since the text and the paragraph numbering were the same in both cases. The experts from the Netherlands, UK and T&E expressed their support to ECE/TRANS/WP.29/GRPE/2016/4. The expert from EC volunteered to review Regulation No. 101 to align it with this proposal at the next GRPE session in June 2016. He also clarified that the correlation program between WLTP and NEDC ensuring that both tests were properly coupled would not be affected by this proposal.

12. GRPE adopted ECE/TRANS/WP.29/GRPE/2016/4 with the following correction:
Title of the document, amend to read:
“Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 (Emissions of M1 and N1 vehicles).”

13. GRPE requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2016 sessions as draft Supplement 7 to the 06 series of amendments and draft Supplement 3 to the 07 series of amendments to Regulation No. 83.

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.
