Overview of the international testing program intended to assess and validate the proposed WLTP procedures.

Progress report of the WLTP-DTP subgroup on Lab Process-Electric Vehicles (E-LabProc).

A flowchart depicting the process for coordinating work among the WLTP test procedures (DTP) and drive cycle (DHC) subgroups and the “drafting coordinator” in the preparation of the light vehicle emissions GTR.

This document presents the position of OICA working groups on
WLTP mode construction. The proposal covers mode construction for conventional vehicles with options to be tested in Validation 2, including for electrified vehicles.

Summary of the 8th meeting of the informal group developing the test procedures for the WLTP GTR.

Revised proposal to support development of the WLTP test procedures.

Agenda for the ninth session of the informal group working on the test procedures for the worldwide light vehicle emissions test procedure.

Paper intended to explore the inclusion of vehicle families in the WLTP GTR. In principle, global technical regulations (GTR) are restricted to technical issues such as test cycles and procedures and do not include definitions of families.

Review of the program for validation of both the new WLTP test cycle and the new WLTP test procedure towards producing a final evaluation report.

Status of the work on drafing the global technical regulation on light vehicle emissions test procedures.

Project schedule for the development, validation, and finalization of the global technical regulation on light vehicle emissions testing by the end of 2012.

Presentation on the combined approach for vehicle test weight, stepless inertia and vehicle selection developed by RDW, ICCT, and T&E.

Explanation of the proposal from RDW, T&E and ICCT for an improved definition of vehicle test mass as well as the proposal from ICCT to substitute the current step-based inertia class system by a step-less approach.

ACEA review of issues requiring resolution pursuant to the phase 2 validation of the WLTP test procedures.

Progress report of the WLTP subgroup working on the test procedures for measuring emissions of pollutants not covered by other subgroups (NO2, N2O, NH3, etc.).

Progress report of the WLTP subgroup working on test procedures for particulate measurement.

Progress report of the WLTP subgroup working on lab procedures for testing of electric vehicles.

Progress report of the WLTP subgroup working on lab procedures for testing of internal combustion engines.
