24. The Secretary of the informal group on Worldwide harmonized Light vehicle Test Procedures (WLTP) reported together with the chairmen of the two subgroups on the Development of the Harmonized driving Cycle (DHC) and on the Development of the Test Procedure (DTP) (GRPE-61-14). GRPE acknowledged the excellent work done by Messrs. Mills (United Kingdom) and Olechiw (United States of America) during their chairmanship of the WLTP informal subgroups DHC and DTP. GRPE welcomed the commitment of Mr. Parkin (United Kingdom) to co-chair DHC together with Mr. Ishii (Japan) and of Mr. D’Urbano (Switzerland) to co-chair DTP together with Mr. Marathe (India). GRPE noted the intention by the WLTP subgroups to set up a Drafting Group (DG) for the development of the gtr text.

25. The Secretary of WLTP informed GRPE about the possible delay in collecting data. Recalling the tough time-schedule to finalize the first step of the new gtr on WLTP, the expert from EC underlined the need to stick to the initial time line of the DHC subgroup. The experts from China and India reported that the national collection of data was still in progress and could not be concluded by the end of January 2011 due to difficult climate conditions in some of the regions during the data collection process. The experts from China and India volunteered to submit, as far as possible, by the end of January 2011 the data partially already collected. It was agreed that China and India would confirm, at the forthcoming session of WP.29 in March 2011, their submission of further data sets.

26. The GRPE Chair underlined the importance to keep the start of validation phase 2 on schedule (October 2011) to avoid a delay in the development of the gtr on WLTP. He announced his intention to inform WP.29 and AC.3, at their March 2011 sessions, about the circumstances of a possible delay in developing the DHC test cycle. He recommended leaving this issue to the decision of WP.29 and AC.3.

27. The Secretary of WLTP presented GRPE-61-24 proposing possible actions to a number of open issues. GRPE supported these actions and noted the intention of both subgroups to hold further meetings end of February respectively mid of April 2011. Detailed information on the activities of both groups is available on the GRPE websites at: www.unece.org/trans/main/wp29/wp29wgs/wp29grp/wltp_dhc07.html and www.unece.org/trans/main/wp29/wp29wgs/wp29grp/wltp_dtp05.html.
