Tokyo, 15 May 2008: Toyota Motor Corporation today said that the cumulative sales of its Prius hybrid car had topped 1 million units worldwide since its launch just over a decade ago.

Prius, the world's first mass-produced gasoline-electric hybrid car, first went on sale in Japan in late 1997 and in other markets in 2000. Toyota remains the leader in hybrid sales, with Honda Motor Co a distant second with its Civic model.

Toyota, the world's biggest automaker, said it had sold about 10,28,000 Prius cars as of the end of April 2008.

"Toyota believes that Prius vehicles worldwide have contributed to a reduction in carbon dioxide emissions by producing approximately 4.5 million tonnes less CO2 when compared with gasoline-powered vehicles in the same class and of similar size and driving performance," it said in a statement.

Toyota remodeled the Prius with an improved hybrid system in 2003 and is widely expected to launch a third-generation version by next year.

By slashing production costs for the hybrid system, Toyota has said it would make the technology available across its line-up, with an aim to sell at least 1 million hybrid vehicles annually soon after 2010.

Last year, Toyota sold about 4,29,400 hybrid vehicles globally, up 37% from 2006. That accounted for less than 5% of its total vehicle sales.
