The voting is done and Toyota just made it official: Prii is the plural of Prius.

For the past month or so, Prius has sponsored a promotion in which anyone could vote online as to what they thought the plural of Prius should be. It was intended to hype the new additions to the line that showcases the nation's best-selling hybrid. Beside the original Prius, they include the Prius V crossover and the Prius C small, sporty version. Oh, and a plug-in electric, but Toyota is unlikely to make or sell many of those.

Anyway, according to the special website which you can see by clicking on the ad at right or here, the made-up term Prii won with 25% of the vote. Interesting considering it had been leading for a long time by wider margins. Prius, for both singular and plural, was second only 1 percentage point behind. Priuses got 20%; Prien, 19%; and Prium, 13%. Toyota vows it will use the winner, Prii, in advertising. Make sense to us: We've been using Prii as long as we can remember. You known, Prii, made by Toyotans.
