Federal Motor Vehicle Safety Standards; Minimum Sound Requirements for Hybrid and Electric Vehicles
This interim final rule responds to an "emergency petition" submitted by the Alliance of Automotive Innovation (Alliance) regarding the phase-in and compliance requirements of Federal Motor Vehicle Safety Standard No. 141 (FMVSS 141), "Minimum sound for hybrid and electric vehicles." The petition details the challenges manufacturers have encountered in complying with FMVSS 141 due to disruptions in the supply chain caused by the Coronavirus Disease 2019 (COVID-19) public health emergency. The petition requests three changes to the phase-in and compliance requirements of FMVSS 141. After considering the concerns raised in the petition, NHTSA has decided to grant the petition, in part, by electing to defer the phase-in and compliance dates by six months. NHTSA is denying the request for an alternative performance option during the phase-in period.
