FROM 2017 TO 2019
From September 2017 to September 2018, all new-to-market vehicles (new model/engine) must be certified under the WLTP test.
From September 2018, all new vehicles sold in dealerships must be certified using WLTP.
From September 2017 until the end of 2018, to simplify the process with respect to customers, regulatory authorities have asked all manufacturers to continue to communicate only the NEDC results. Accordingly, the results of all WLTP-certified vehicles must be converted to their NEDC equivalent until early 2019.
As from January 2019, all published data will be only WLTP values.
