73. The representative from the US, Co-Chair of the IWG on EVE presented the status report introducing the latest activities of the group (GRPE-87-52). With respect to UN GTR No. 21, the representative from OICA agreed that all gaps should be bridged to account for the fact that the whole vehicle is being tested and not a powertrain in a laboratory. Regarding UN GTR No. 22, he raised the remaining issue of category 2 vehicles that would need urgent action. He proposed to consider the possibility to look at energy throughput as a potential solution to take into consideration the high non-driving energy demand in some applications. The Co-Chair of the IWG on EVE agreed and confirmed the IWG on EVE has a common understanding on the remaining issues to be solved in UN GTRs Nos. 21 and 22.
