Toyota President Fujio Cho said Monday his firm plans to increase its range of hybrid car models to about 10 within five years.
"We want to add one or two models this year, including a full model change," he said. "In four or five years, there will be about 10 models."
Market competition is intensifying for the environmentally friendly gasoline-electric hybrid vehicles. U.S. auto giant General Motors Corp., for example, has said it intends to mount hybrid systems on a number of its models.
Toyota is currently ahead of its rivals, with sales of its hybrid vehicles reaching 130,000 units to date.
A senior Toyota official has said the company is aiming for sales of 300,000 hybrid vehicles by 2005.
