Toyota Prii is the New Plural of Prius

The Toyota Prius is one of those names that until now has defied a plural categorization. With Toyota poised to roll out several new Prius models over the next few years, the time was right to determine what the plural of Prius should be. The people have spoken, and Prii has emerged a winner.
To help it determine the name, Toyota took the vote to the people with a campaign that began at the 2011 Detroit auto show and concluded at the Chicago show.

In the ensuing six weeks, more than 1.8-million voters cast ballots. The competitors were: Prius, Priuses, Prium and Prien in addition to Prii. While Prii won with some 25 percent of the votes, it was close, as Prius came in just a percentage point behind.

Helping to add an air of legitimacy to the process was the announcement by that it will officially add Prii to its Prius entry as the car’s plural name.

Toyota is going big with the Prius family in the near future. Coming soon is the Prius plug-in (check out our Prius PHEV test here), while the Prius v and Prius c concepts at the Detoit show and the Prius + concept coming to the 2011 Geneva show foreshadow future Prius-branded vehicles. That’s a lot of Prii.
