A total of 332 owners participated in the event.

Toyota has set a new Guinness World Record for having the most vehicles in a hybrid parade.

The event took place on April 23rd at the Naval Air Station Alameda in California and saw 332 Prius owners participate in the event. Toyota didn't much to say about the parade but guests were apparently invited to drive on a specially designed course, enjoy some food, and have a chance to win prizes.

Toyota decided to host the event in California because the golden state accounts for 40 percent of all Prius sales in the United States.  The company went on to say Toyota and Lexus have twice as many hybrids on the road as any other automaker.

In a statement, Toyota Motor Sales general manager and vice president Pete Carey said "The Bay Area is home to hundreds of thousands of proud Prius owners, and we wanted to pay homage to the Prius this Earth Day."  Carey went on to say the Prius is a "revolutionary vehicle and the folks behind the wheel who’ve always been our early-adopters, thinking bigger about their carbon footprint and environmental impact.”

As a refresher, the latest Prius has a 1.8-liter Atkinson cycle four-cylinder engine, two electric motor/generators, and an electronically controlled continuously variable transmission.  This enables the model to produce a combined maximum output of 121 horsepower and return an EPA-estimated fuel economy rating of up to 58 mpg city / 53 mpg highway / 56 mpg combined.
