The Chair of GRSP, on behalf of the Chair of the IWG, informed GRSP about the third meeting of the IWG on QRTV held in Brussels 16-18 April 2013 at the headquarters of the European Automobile Manufacturers’ Association (ACEA). She informed GRSP that the main discussion included the start of a framework for the draft UN GTR. Therefore, the group considered the recent Notice of Proposed Rule Making published by the National Highway Traffic Administration (NHTSA), on minimum sound emissions for electric and hybrid-electric vehicles and a Japanese proposal seeking to use its national guidelines as a basis for the UN GTR. However, she added that the IWG had not yet started discussion on performance requirements, test procedures or limit values. GRSP noted that the next meeting of the IWG was scheduled on 16 – 18 July 2013, at NHTSA headquarters.
