· From September 2017-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
· However, to make the transition simpler, throughout 2018 , regulatory authorities have asked all manufacturers to continue to communicate only the NEDC results. How do we do that? Vehicles that are already being certified under WLTP will have their results converted to the NEDC equivalent until January 2019.
· Effective January 2019, all published data will likely be WLTP values (with a possibility of NEDC for reference)
· In parallel to the improvements in testing (WLTP & RDE) the Euro 6 standard that vehicles have to respect is evolving step by step to reduce the emissions of local pollutants. This will ultimately lead to the rollout of the Euro 6D standard on 1st January 2020.
