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.
