Proposal to amend the charger requirement and the measurement method of REESS current for a hybrid electric power train in order to align UN R101 with the provisions in UN R154 and introduce the option to determine road load values for Pure Electric Vehicles according to the requirements of UN R83.

Revised proposal, superseding the original proposal, to clarify the wording regarding the use of the reference fuel required for emission testing, to permit testing with the same reference fuel used for emission testing, and to align with recently adopted amendments to Regulation No. 85.

Proposal to extend to the 05 series of amendments the option from the 06 and 07 series to use the calculation of road load values determined according to UN GTR 15 (WLTP).
