WLTP-DTP-LabProcICE-262_1
Positions on open points WLTP DTP subgroup LabProcICE
Incl. initial proposals from LabProcICE leading team,
Based on input by the following stakeholders:
Drafting Coordinator
Japan (LabProcICE-250)
EU-COM (LabProcICE-254rev2)  ANNEX 7 to 9
General remarks:
This presentation includes the comments which were decided by LabProcICE leading team to be confirmed or discussed at the f2f meeting. All other issues/comments which are purely editorial or already approved by LabProcICE leading team will be reviewed and transposed by the Drafting Coordinator.
The input from other stakeholders has been transposed to the LabProcICE master amendment draft (LabProcICE-263)
Remark on EC comments:
The comments by Iddo Riemersma (IR) were taken from the document LabProcICE-rev2.
Please note: Unfortunately the numbering of the comments is not consistent with Revision 1.

9. 6. Fuel consumption calculations for ICE vehicles
NEW:
6. Fuel consumption calculations for ICE vehicles
JAPAN:
Annex6, Appendix 2, includes fuel consumption correction fomula, but original fuel consumption formula does not exist in gtr except for HEV vehicle (Annex8).
Add new paragraph 6 to ANNEX 7
Fuel consumption formula needed for ICE.
Refer to UN-R101 (see LabProcICE-255rev1).
LabProcICE:
Japan is correct.
Proposal needs to be provided to DC.

JAPAN:
ANNEX 7, includes calculation of the CO2 value for an individual vehicle by the CO2 interpolation method
Add a fuel consumption interpolation method to the gtr (analogous to the CO2 interpolation method)
LabProcICE:
Japan is correct.
Proposal needs to be provided to DC.
