What is the plural of Prius? Priuses? Prii? Prix? Priora. Just Prius? Whatever’s correct, there certainly are lots of the trendsetting hybrid car out there. More than 1 million, in fact.
As of April 2008, worldwide sales of the Prius reached 1,028,000 units. The Prius is sold in more than 40 countries and regions, but the bulk of sales come from North America and Japan.
According to Toyota, all those Prius hybrids have contributed 4.5 million tons less carbon dioxide pollution (the leading cause of global warming) than what would have come from similarly sized gas-only cars purchased instead of the Prius.
And, in case you’re wondering, the official word from Toyota is that Prius works for the singular and plural forms.
