The automaker said Wednesday that the Prius has been the top-selling hybrid in the U.S. since it went on sale 11 years ago.
The Prius is powered by both a gasoline engine and an electric motor. It can get up to 51 miles per gallon in the city and 48 on the highway.
It has become increasingly popular this year as gas prices nationwide have moved toward $4 per gallon.
Toyota says it has sold more than 2 million Priuses worldwide.
The March 11 earthquake in Japan forced Toyota to stop production at most Japanese factories. But the company restarted two plants that make Prius and Lexus models on March 28.
