The Toyota Prius is a full hybrid electric automobile developed by Toyota and manufactured by the company since 1997. Initially offered as a 4-door sedan, it has been produced only as a 5-door hatchback since 2003. The United States Environmental Protection Agency and California Air Resources Board (CARB) rate the Prius as among the cleanest vehicles sold in the United States based on smog-forming emissions. The 2016 model year Prius Eco ranks as the all-time most fuel efficient gasoline-powered car available in the US without plug-in capability.
