【Regulatory Monthly Report】Global Vehicle Regulatory Developments – June 2025

Highlights: Key items in June affecting automotive compliance:

China: The Automotive Data Outbound Security Guidelines (2025 Draft) opened for public comment on June 13, defining assessment scenarios, exemptions, and responsibilities for cross-border transfers of vehicle-generated data. Reuters+1
United States: On June 11, NHTSA issued its interpretive rule “Resetting the Corporate Average Fuel Economy (CAFE) Program,” outlining the legal foundation and constraints for resetting the CAFE and MDHD fuel-efficiency programs. Federal Register+1
United Kingdom (GB): The Road Vehicles (Type-Approval) (Amendment) Regulations 2025 were made on June 9 (in force July 3). GB also updated type-approval technical guidance in June (e.g., alignment on eCall/ADAS/ALKS and telecom transitions). 立法网站+2立法网站+2
Brazil: Under the MOVER program, technical and environmental parameters (energy efficiency, recyclability, safety) apply to vehicles marketed in Brazil as of June 2025. Serviços e Informações do Brasil
UNECE / Automated Driving: In the June session window, GRVA’s task force delivered a status report on regulatory fitness for ADS, mapping current regulations and amendments under consideration for WP.29. unece.org
Cybersecurity deadline approaching: Multiple references reaffirm July 2025 as the full applicability point of UNECE R155/R156 for existing vehicle types—making June a final readiness month for CSMS/software-update compliance. iaf.com

Automotive Data Outbound Security Guidelines (2025 Draft, June 13):
Specifies when AD/ADAS training/validation data is “important” and requires security assessment; outlines FTZ-based facilitation/exemptions and clarifies roles of data processors. Recommendation: implement a data-outbound decision tree spanning R&D, operations, and after-sales; prepare both assessment dossiers and exemption justifications. Reuters+1

CAFE “Reset” Interpretive Rule (June 11):
Clarifies statutory constraints on factors NHTSA may consider when setting “maximum feasible” standards and interprets authority for the MDHD efficiency program. This establishes a procedural foundation for subsequent rulemakings and enforcement. Recommendation: re-validate internal compliance assumptions and litigation posture against the interpretive framework. Federal Register+1

Type-Approval Amendment SI 2025 (made June 9; in force July 3):
Adjusts GB’s independent regime and its incorporation of international rules. June guidance from DfT/VCA also details alignment for eCall sunset (2G/3G) / 4G-5G approvals, ADAS/ALKS, etc. Recommendation: update the regulatory matrix and version control for GB/EU/UNECE, including transitional arrangements. 立法网站+1

GSR reference updates in the pipeline: Although published in late July/August, Delegated Regulation (EU) 2025/1122 bears the date June 5, capturing updates to UN R25/34/79/100/117/127/152 and new UN R167/169/171—already influencing June document preparation and transition planning. Recommendation: reflect the June-dated reference list in type-approval files. EUR-Lex
Battery Regulation: Ongoing delegated/implementing acts in 2024–2025; by late June, industry focus intensified on carbon-footprint, traceability, due-diligence milestones for 2025–2027. Recommendation: operationalize battery passport/due-diligence data flows across suppliers. minespider.com+1

MOVER thresholds effective June 2025: OEMs/importers must meet technical/environmental parameters (efficiency, recyclability, safety). Recommendation: build a Brazil-specific market-access checklist combining MOVER requirements with CONTRAN technical rules. Serviços e Informações do Brasil

R155/R156 countdown: With July 2025 applicability to existing types, June was the final window to close CSMS evidence, SBOM coverage, vulnerability management, and OTA traceability. iaf.com

China / Data Outbound: Stand up a scenario-based register and decision tree; map ADAS/ADS data flows; draft assessment/exemption files. Reuters
US / Fuel-Economy Programs: Align internal models and documentation with NHTSA’s interpretive rule; assess downstream impact on MY2026+ planning and credit strategies. Federal Register
GB / Type-Approval: Refresh regulatory matrices and transition logs for GB vs EU/UNECE; verify eCall/telecom, ADAS/ALKS test plans and dossiers. 立法网站+1
EU / Batteries: Prepare for carbon-footprint, due-diligence, traceability workloads; confirm supplier readiness for data uploads. minespider.com+1
Global / Cybersecurity & Updates: Ensure R155/R156 compliance for existing types ahead of July—CSMS audit trail, software change control, incident response, and OTA compliance package. iaf.com
