Sorry I still dont get it. What is “ev” mean when selected? This one of many selectable options when creating a new topic. etype, news,bodywork,jlr,i-pace are other items that can be selected IE. The limit is 5.
I would hazard a guess EV is for the I Pace group.
EV is short for Electric Vehicle. The tags are common for all the Categories, site-wide. So, not all tags will be relevant for all Categories.
