Toyota Motor Corp. will launch 10 more gasoline-electric hybrid vehicles by first quarter of the next year and boost its worldwide sales of the fuel-sipping models to 1 million units a year.

Jim Press, Toyota's U.S. president and chief operating officer, said the worlds second-biggest automaker aims for hybrid vehicles to account for at least 25 percent of its U.S. sales in the same time period.

The automaker had primarily set a goal of selling 300,000 hybrid vehicles per year globally by this year or next.

Press said in a speech, “At our current rate of sales, that's about 600,000 hybrids in the U.S. To achieve that goal, we will have to look at offering hybrid power systems in virtually all our vehicles, including trucks.”

The future models include already-announced hybrid versions of Toyota's best-selling Camry sedan and Lexus GS sedan, Press said, declining to reveal the other models that are under development.

Toyota sales growth has been driven by popular models that include the Prius gas-electric hybrid car, which has seen increasing demand in the face of high U.S. gasoline prices.

U.S. sales of the Prius were up 92 percent at 9,691 vehicles in July. Toyota also sold 2,564 hybrid versions of its Highlander sport utility vehicle and 2,262 Lexus RX 400h luxury SUVs. The Lexus hybrid SUV was launched in April.
