........ where is WLTP going to lead us UK Pagoda owners?
From what I have read this testing criteria only applies to newly manufactured vehicles. Apparently there is no effect on vehicles manufactured prior to 2017.
Although the “W” in WLTP stands for “Worldwide” this appears to be an EU effort. I have not found a reference to use in the USA but I would assume USA manufacturers selling into the EU would need to comply for new models.
