Proposal to introduce ASEP requirements for L4 and L5 category vehicles with PMR > 50 W/kg. The proposal aligns ASEP for high powered L4 and L5 vehicles, used for passenger transport, with UN Regulation No 41.04 due to comparable sound emissions levels of L4 and L5 vehicles with the ones of L3 vehicles and the possibility of applying similar measurement methods for sound emissions for those vehicle categories. This proposal is supported by the Commission study on enhanced sound requirements for mopeds, quads and replacement silencers of L-category vehicles which resulted in amendments to UN Regulation Nos 9, 63 and 92 (ref. document WP.29/2017/2).
