The 18th session of the Children Left in Vehicles Informal Working Group convened online on 25 June 2026. Feedback from GRSP on the draft UN Regulation for buses and coaches was positive, with a 10 July submission deadline for further comments. Australia will circulate a preliminary draft UN Regulation for light vehicles to Vice-Chairs before the September face-to-face meeting in Paris. The bus UN Regulation will initially include only Physical Inspection Systems, while light vehicle discussions will address indirect, indirect-plus, or direct sensing systems. A trilateral meeting between Australia, the United States, and Canada made constructive progress on Global Technical Regulation development, with potential for a November WP.29 vote.
The Classic Car Retrofit Consortium represents SMEs performing small-series and classic car retrofits, averaging around 10 vehicles per year. The current draft regulation applies OEM-level type-approval logic designed for large-series fleet retrofits, which would eliminate the existing SME sector without materially improving safety. Specific challenges include destructive REESS testing costs of approximately 100,000 EUR per battery pack type, full-vehicle EMC testing costs around 30,000 EUR per car, and cybersecurity requirements unsuitable for classic vehicles. CCRC proposes either clarifying the regulation’s scope to exclude classic car retrofits, or developing a tailored regulatory framework specifically for classic cars produced in small numbers.
This consolidated draft text proposes uniform provisions for approving vehicles transformed into electric vehicles (EV) or hydrogen fuel cell vehicles (HFCV) with electric powertrain retrofit systems. The regulation defines retrofit systems as all devices and components necessary to operate vehicles in electric mode, including powertrains, energy storage systems, management systems, and vehicle inlets. It specifies application procedures, marking and approval requirements, technical specifications for retrofit systems, installer qualifications and authorization, conformity of production procedures, modification and extension of approvals, and penalties for non-compliance. The regulation applies to vehicles of categories M and N and requires compliance with relevant UN Regulations including those addressing electromagnetic compatibility, braking, power measurement, and electric powertrains. Specific technical requirements address surveillance systems, anti-tampering provisions, performance parameters, dimensional and mass tolerances, and acoustic devices.
The provisional agenda for the tenth meeting of the Informal Working Group on EV/HFCV Retrofit Systems on Thursday 2nd July 2026 includes adoption of the agenda, approval of minutes, coordination and organization of work with reference to GRPE-92-14, EV/HFCV-02-02, GRPE-93-22/Rev.1, GRSP-78-17, GRVA-25-19, and WP.29-199-16, electrical safety review, braking, EMC, power determination and battery range, UN Draft, and any other business, with subsequent meetings scheduled for 9th September online and 8th October online.
The Informal Working Group on EV/HFCV Retrofit Systems held its ninth meeting on 11th June 2026. The group discussed electrical safety, cybersecurity, braking, EMC, power determination, battery range, and the overall approval concept for retrofit systems. Discussions covered UN Regulations 100, 155, 13/13-H, 10, 85, 177, 154, and 138. The group agreed to approve retrofit systems together with compatible vehicle families and to exclude hydrogen fuel cell provisions pending further technical input. RME agreed to coordinate benchmarking exercises on power thresholds and range/durability requirements. Future meetings were scheduled for 2 July 2026, 9 September 2026, and 8–9 October 2026.
Proposal to add para. 6.2.1.3 defining method of measurement in the frequency range 1 GHz to 6 GHz, add para. 6.2.2.5 establishing limits of disturbance with peak detector at vehicle-to-antenna spacings of 3.0 ± 0.05 m and 10.0 ± 0.2 m, add para. 6.3.2.5 establishing limits of disturbance with average detector at vehicle-to-antenna spacings of 3.0 ± 0.05 m and 10.0 ± 0.2 m, rename para. 6.5.2 to specify frequency range 30 MHz to 1000 MHz, add para. 6.5.3 establishing ESA broadband type approval limits in the frequency range 1 GHz to 6 GHz with measurement frequency requirements based on highest internal frequency, add para. 7.3 establishing specifications concerning narrowband electromagnetic radiation from vehicles with method of measurement and type approval limits, rename para. 7.10.2 to specify frequency range 30 MHz to 1000 MHz, add para. 7.10.3 establishing ESA broadband type approval limits in the frequency range 1 GHz to 6 GHz with measurement frequency requirements, add Annex XY defining method of measurement of radiated broadband and narrowband electromagnetic emissions from vehicles in the frequency range 1 GHz to 6 GHz, add Annex XZ defining method of measurement of radiated broadband electromagnetic emissions from electrical/electronic sub-assemblies with test setup figures, and add Appendices z1 and z2 establishing vehicle reference limits at 10 m and 3 m antenna-vehicle separation respectively.
The European Commission presents prioritized proposals toward updating UN R10 to address transformative vehicle technologies including electrification, automated systems, steer-by-wire, V2X communication, and software-defined vehicles. Current interpretation does not guarantee safety and environmental protection under real road conditions. Proposals include assessing radiated emissions from four vehicle sides rather than two, testing under normal driving conditions, and establishing agreement on drive cycles and transients. These proposals align with WP.29 guidance, improve safety, ensure reproducibility, and represent adaptation to technological progress, based on follow-up of EMC-46-04 and EMC-49-09.
