Proposal to introduce levels in the draft new UN Regulation on Real Driving Emissions type approvals based on the following: - Since RDE testing has been introduced in the European Union, there has been criticism of the difficulties encountered when planning a valid RDE test.
- This situation would be worsened by introducing the requirement for a test to be suitable for analysis according to both 3-phase and 4-phase concepts.
- As levels have already been introduced in Regulation No. 154 and these are becoming accepted and understood by technical services and approval authorities, the introduction of these levels in this Regulation would be a clear alignment.
- As the temperature boundary conditions from this draft Regulation are already being transposed into European legislation, OICA members see no need to differentiate between boundary conditions for the proposed levels.
- The inclusion of these few amendments would return the planning burden to that currently experienced in the EU, at least for markets which apply the 4-phase WLTP concept.
