7. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/10 and GRPE-83-15 extending the acceptable reference fuels and road load determination methodologies and clarifying crankcase pressure measurement and four-wheel drive vehicles tests in the 05, 06 and 07 series of amendments to UN Regulation No. 83. The representative from the UK requested further details on the road load determination proposal.
