Proposal to amend additive deterioration factors and the PEV run-in requirement and to effect corrections and editorial improvements.

Draft proposal to align the Regulation with the latest regional requirements (e.g., Euro 7) as submitted to GRPE (Informal document GRPE-92-09e).

Review on the possible direction
(1) new series of amendment
(2)single series structure

Proposal to introduce optional calculation method for determining f₀ and f₂ road load coefficients, allow measurement of drivetrain delta on component dynamometer, permit evaluation of split runs to increase data base, and enable test vehicle configuration using interpolation method. The calculation method determines final f₀ and f₂ values considering theoretical delta between coast down vehicle and final vehicle. Component dynamometer measurement increases accuracy because not all combinations of road load relevant components can be assembled, allowing all component combinations to be evaluated independently.

Proposal to bring clarity in the text relating to On-Board Diagnostics (OBD).

Proposal concerning the approval of the wind tunnel facilities.

Calibration of measurement equipment to PN10 measures more particles than calibration to PN23. It is therefore logical that compliance with a limit when measured according to PN10 demonstrates compliance with the same limit according to PN23 but this text should be added for legal certainty.

Small Volume Manufacturers (SVMs) are defined as manufacturers producing fewer than 10,000 M1 or 22,000 N1 vehicles annually in the European Union. Ultra Small Volume Manufacturers (USVMs) produce fewer than 1,000 vehicles annually. SVMs receive exemptions from certain systems and testing requirements, including OBM, EEEDWS, and OBFCM installations for M1 and N1 vehicles. Type approvals granted before July 1, 2030 remain valid. In-service conformity checks are not mandatory for SVMs.

Proposal for a new UN Regulation for Uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to On-board monitoring (OBM) systems, environmental vehicle passport (EVP) and in-vehicle display of environmental data. An informal document amending this proposal is under development.

Proposal to harmonise and consolidate the regional procedures and limits, update the provisions to align with Euro 7 requirements, including new particle number (PN10) provisions, a new SHED limit for evaporative emissions, updated On-board Fuel Consumption Monitoring provisions, new annexes with requirements relating to in-vehicle battery durability and a new test for range of Pure Electric Vehicles at low temperatures. An informal document amending this proposal is under development.
