Presentation concerning heavy-duty hybrids.

Presentation of the results of the validation test program 1 and status of test program 2 (Chassis dyno test program at JRC, HDH drive cycle investigation, and HILS/SILS model verification) and review of open issues for drafting the GTR text.

Japan analysis of JRC chassis dyno test results under the Validation Test Program 2.

Discussion of vehicle characteristics to be taken into account (or left out) in order to ensure an optimally harmonized set of heavy-duty vehicle test procedures for worldwide use.

Since the system output is different between WHTC, the test cycle for conventional vehicles, and WHVC, a compensation method has been proposed. JASIC reports on its verification of the compensation method and its impact on test results.
