Proposal to correct errors and clarify provisions based on requirements introduced in the Amendment 6 to UN GTR No. 15.

Proposes updates and amendments to proposal to introduce new requirements relating to Auxiliary Emission Strategies, cold engine starts and the use of Portable Emissions Measurement Systems (PEMS) to measure particle numbers

Clarifications regarding “coasting” and twin roller dynamometers in 4WD operation.

Proposal to address use of the phrase “if PN measurement is required” throughout the regulation given that PN measurement in both Level 1A and Level 1B is now required.

Proposal to modify provisions of the 01 series pursuant to consideration of the proposal to address the use of the phrase “if PN measurement is required” in the original text of the regulation.

This proposal introduces the new Utility Factor (UF) approach proposed in the Euro 6e emissions type-approval legislation. In addition, as a result of the application of the new tyre labelling Regulation (EU) 2020/7401, this proposal introduces a revised format of the table with tyre energy efficiency classes according to rolling resistance coefficients (RRC), in-line with the format proposed in the Euro 6e emissions type-approval legislation.
