EU TCMV approves Euro 6e amendments
11 August 2022
At its 96th meeting last month, the European Commission’s Technical Committee on Motor Vehicles (TCMV) approved amendments to Regulation (EU) 2017/1151 regarding type approval of motor vehicles with respect to emissions from light passenger cars and commercial vehicles. Some of the key changes are:
- A new Euro 6e step is added effective September 2023 that introduces revisions to the RDE test procedure and other regulatory changes. The new regulation redefines the former conformity factors (CF) as PEMS error margins. The values are reduced in line with the 2021 JRC report on conformity factors [5057]. The Euro 6e step includes a revised NOx margin of 0.10 (i.e., a CF = 1.10, down from 1.43) and a reduced PN margin of 0.34 (CF = 1.34, down from 1.5).
- The Euro 6e amendments repeal obsolete provisions for the rules on access to vehicle onboard diagnostics (OBD) information and vehicle repair and maintenance information, which were incorporated into Regulation (EU) 2018/858.
- The amendments also include the utility factor (UF) update for hybrid vehicle charging, where the normalized distance is to be revised by 31 December 2024, taking into account the real-world fuel consumption data recorded by on-board fuel consumption monitoring (FCM) devices and collected under Implementing Regulation (EU) 2021/392.
As typical for earlier EU regulatory stages, Euro 6e is introduced in several sub-steps:
- Euro 6e—September 2023/4 (new types/all registrations): The main changes include RDE compliance considering updated PEMS margins (above) and on-board FCM for category N2 vehicles.
- Euro 6e-bis—January 2025/6: Increased extended ambient conditions for RDE compliance (the upper RDE temperature limit for moderate temperature changes to 35°C from 30°C and the upper limit for extended temperature to 38°C from 35°C)
- Euro 6e-bis-FCM—January 2027/8: Onboard fuel and/or electric energy consumption monitoring device.
The Euro 6e amendments reflect the adaptation to technical progress achieved in the UN World Forum for Harmonization of Vehicle Regulations (WP.29) on the UN Regulation No. 154 for the Worldwide harmonized Light-duty vehicles Test Procedure (WLTP) and in the draft UN Regulation on Real Driving Emissions (RDE).
At the same 96th meeting, the TCMV approved two more items: (1) a Regulation amending Commission Regulation (EU) No 582/2011 regarding the type-approval of heavy-duty vehicles, adding pure biodiesel (B100) as a new reference fuel; and (2) a proposal for a Commission implementing act laying down rules for the application of Regulation (EU) 2019/2144 of the European Parliament and of the Council with regards to uniform procedures and technical specifications for the type-approval of the automated driving system (ADS) of fully automated vehicles for heavy-duty vehicles.
