Agenda Item 5.
Main part & Cycle issues (Annex 1 & 2)

Downscaling / gearshifting (OIL #4-9): Progress report was given by H. Steven (WLTP-11-05e), incl. status of n min_drive. . Since there could not be achieved a common position in the TF, issue of nmin_drive will be further worked on.

OIL # 06: Use of the gear box: Crawler gear (WLTP-11-06e) prescription was developed and accepted by TF. Revised gtr text proposal for annex 2 (WLTP-11-07e) was explained. OICA requested to include the factor 0.15 for M1. Amendment was accepted by IWG. Japan supported the proposal. Proposal was adopted by WLTP IWG with the above mentioned amendment by OICA. Text will be provided to the DC by Heinz Steven.

NEW OIL #1b_6: Additional discussion points from the TF (WLTP-11-08e)
Annex 1:
a) Section 2: vehicle classification (test mass inst. of kerb mass) has to be defined further.
b) Section 3: add checksums of the vehicle speed
c) Section 7: report detailed downscaling information

Annex 2: Calculation of average gear over the whole cycle

IWG asked the TF to develop proposals for these issues. EU asks for development for a communication concept for the required data.
