Just to let yall new peeps know. It was decided by the people a while ago that the proper term for multiple prius is "Prii" I would attach links but since I'm new I'm not able, but feel free to look it up. Just thought I'd share that for anybody who didn't know. SPREAD THE WORD!
Isn’t this a bit behind the times? The Prius c and Prius v models are long gone from U.S. new-car showrooms—but for readers who missed the “Prius Goes Plural” campaign the first time, see the press release, video (1), video (2), and video (UK). Anyway, trademarks are proper adjectives, so in the @Elektroingenieur Style Manual, it’s Prius cars or Prius vehicles.
Honestly I thought Priuseses had a certain grace to it, much like the cars themselves when seen in groups.
