Why is this page in the Smart vehicles Category?

edit

I noticed recently that this page was in Category:Smart vehicles. Does it have anything to do with the Smart Forfour? Because down by the External Links section, the category says |Forfour at the end. Is there an explanation for this? There’s nothing in the text that related to Smart Soultech99 (talk) 14:55, 4 January 2023 (UTC)Reply
