Consolidated revision to make corrections, clarifications and improvements that have already been introduced into the 02 and 03 series of amendments of UN R154. The proposal is based on document GRPE/2024/3, GRPE-90-11-Rev.1, and GRPE-91-11 PEV run-in provisions only).

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

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 concerning the approval of the wind tunnel facilities.

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

This proposal intends to establish a definition for ‘Hydrogen ICE vehicle’ and the related method for ‘trip validation’

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.

Proposal for a new series to align with Euro 7 requirements, including provisions on manipulation devices and manipulation strategies, anti-tampering, security and cyber security, and extended lifetime and In-Service Conformity requirements for in-vehicle battery durability. The Type 2 test has been removed from this new series. An informal document amending this proposal is under development.

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.

Proposal to align the real-driving emissions provisions with the requirements of Euro 7 and to introduce a “levels” concept. An informal document amending this proposal is under development.

Proposal to align the scope with the Euro 7 emissions legislation. An informal document amending this proposal is under development.

Proposal from the informal group on Environmental and Propulsion Performance Requirements of L-Category Vehicles to align the provisions of UN R40 with the Euro 3 emissions standard.

Proposal from the Informal Working Group on Automotive Life Cycle Assessment to establish a resolution with recommendations for use by Contracting Parties to the 1958 and 1998 Agreements and others when assessing the CO₂ emissions over the life cycle of motor vehicles.

Proposal to transpose GTR 24 on laboratory procedures for the measurement of brake particle emissions into a UN Regulation. An informal document amending this proposal is under development.

Proposal to amend UN R83 by deleting Annex 1, paragraph 3.4.3. and renumbering paragraphs 3.4.3.1., 3.4.3.1.1., 3.4.3.1.2. and 3.4.3.1.3. to read 3.4.3., 3.4.3.1., 3.4.3.2. and 3.4.3.3., and deleting Annex 2, paragraph 1.9.2. The concept of “Operating Mode Switch” has been removed from the Regulation and these two paragraphs were omitted from this removal and should be deleted from both the manufacturer’s information document and the addendum to the approval certificate.
