Report of the expert group (WLTP-DHC informal group) on their development of the driving test cycle for the Global Technical Regulation on light-duty vehicle emissions and fuel consumption (World Harmonized Light-duty vehicle Test Procedures).

Presentation prepared by the WLTP secretary for discussion at the 5th informal working group session.

Agenda for the meeting to launch “Phase 1b” for the further development of the proposed GTR on light vehicle emissions.

Notification of the first meeting to work on refinements to the GTR on light vehicle emissions that will likely be voted on at the World Forum session next March. This new phase of work (“phase 1b”) expects to produce an amendment to the GTR that will address technical elements set aside in the interests of meeting participant deadlines for establishing the basic test cycles.

Proposal for a further “phase 1b” in the development of the GTR on light vehicle emissions. In order to meet Contracting Party objectives, the draft GTR has been submitted for adoption by the Forum in March 2014. Although the current draft offers a complete test cycle, the WLTP experts want to improve the regulation by further addressing a number of technical elements that were set aside due to time and resource constraints.
