{"abstract":"The Department of Energy (DOE) is revising its regulations on electric vehicles to provide a petroleum-equivalency factor (PEF) and procedures for calculating the petroleum-equivalent fuel economy of electric vehicles. The petroleum-equivalent fuel economy values of an automobile manufacturer's electric vehicles may be included in the calculation of that manufacturer's corporate average fuel economy (CAFE), according to regulations prescribed by the Environmental Protection Agency and the Department of Transportation.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF ENERGY","name":"Energy Department","id":136,"url":"https://www.federalregister.gov/agencies/energy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/136","parent_id":null,"slug":"energy-department"},{"raw_name":"Office of Energy Efficiency and Renewable Energy","name":"Energy Efficiency and Renewable Energy Office","id":137,"url":"https://www.federalregister.gov/agencies/energy-efficiency-and-renewable-energy-office","json_url":"https://www.federalregister.gov/api/v1/agencies/137","parent_id":136,"slug":"energy-efficiency-and-renewable-energy-office"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2000/06/12/00-14446.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"474","title":10}],"citation":"65 FR 36986","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective July 12, 2000.","disposition_notes":null,"docket_ids":["Docket No. EE-RM-99-PEF"],"dockets":[{"supporting_documents":[],"agency_name":"EERE","documents":[{"comment_count":0,"comment_start_date":"2023-04-26","updated_at":"2023-04-26T09:56:44.155-04:00","comment_url":"https://www.regulations.gov/commenton/EERE-2023-VT-0009-0008","allow_late_comments":null,"id":"EERE-2023-VT-0009-0008","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"EERE-2023-VT-0009","title":"1999 Advanced Automotive Technologies Petroleum-Equivalent Fuel Economy Calculation (PEF), Legacy Docket No. EE–RM–99–PEF,  (see also, EERE-2021-VT-0033)"}],"document_number":"00-14446","effective_on":"2000-07-12","end_page":36992,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2000/06/12/00-14446.xml","html_url":"https://www.federalregister.gov/documents/2000/06/12/00-14446/electric-and-hybrid-vehicle-research-development-and-demonstration-program-petroleum-equivalent-fuel","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/00-14446?publication_date=2000-06-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2000-06-12/00-14446/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":1251,"last_updated":"2026-07-28 16:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2000-06-12/pdf/00-14446.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2000-06-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2000/06/12/00-14446.txt","regulation_id_number_info":{"1904-AA40":{"issue":"200004","html_url":"https://www.federalregister.gov/regulations/1904-AA40/equivalent-petroleum-based-fuel-economy-calculation-for-electric-and-hybrid-electric-vehicles","title":"Equivalent Petroleum-Based Fuel Economy Calculation for Electric and Hybrid Electric Vehicles","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200004&RIN=1904-AA40&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["1904-AA40"],"regulations_dot_gov_info":{"supporting_documents":[],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/1904-AA40/equivalent-petroleum-based-fuel-economy-calculation-for-electric-and-hybrid-electric-vehicles","title":"Equivalent Petroleum-Based Fuel Economy Calculation for Electric and Hybrid Electric Vehicles"},"comments_count":0,"agency_id":"EERE","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EERE-2023-VT-0009","supporting_documents_count":0,"docket_id":"EERE-2023-VT-0009","document_id":"EERE-2023-VT-0009-0008","regulation_id_number":"1904-AA40","title":"1999 Advanced Automotive Technologies Petroleum-Equivalent Fuel Economy Calculation (PEF), Legacy Docket No. EE–RM–99–PEF,  (see also, EERE-2021-VT-0033)","checked_regulationsdotgov_at":"2023-04-27T13:00:12Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":36986,"subtype":null,"title":"Electric and Hybrid Vehicle Research, Development, and Demonstration Program; Petroleum-Equivalent Fuel Economy Calculation","toc_doc":"Electric and hybrid vehicle research, development, and demonstration program; petroleum-equivalent fuel economy calculation","toc_subject":"Energy conservation:","topics":["Electric power","Energy conservation","Fuel economy","Motor vehicles","Research"],"type":"Rule","volume":65}
