Toyota plans to install solar panels on some Prius hybrids in its next remodelling, responding to growing demand for "green" cars amid record-high oil prices, a source briefed on the matter said yesterday.
The panels, supplied by Kyocera would be able to power part of the air-conditioning on high-end versions of the gasoline-electric Prius, the source said.
"It's more of a symbolic gesture," said the source, who asked not to be identified. "It's very difficult to power much more than that with solar energy."
Toyota is due to launch the third-generation Prius next year.
Big automakers are all racing to come up with alternative solutions to using fossil fuels to appear ecologically conscious and to lure consumers looking to save money at the pump.
But solar power is not seen as a viable solution to power cars. Solar panels are expensive due to rising silicon prices and storing energy is difficult, the source said. It was unknown how much the solar panels on the new Prius cars would cost, or how many solar-mounted versions Toyota would build.
A Toyota spokesman declined to comment, saying the company does not talk about future product plans.
Toyota has struggled to keep up with demand for the Prius as soaring gasoline prices put consumers off of gas-guzzling sport utility vehicles and pickup trucks. Rival Honda will also step up its hybrid push with a new, low-cost model early next year, followed by several other gasoline-electric cars.
Automakers have teamed up with battery makers to develop and produce lithium-ion batteries to store more energy in smaller packages to extend cruising distances.
Toyota has partnered with Matsushita Electric Industrial while Nissan has a joint venture with the NEC group and Mitsubishi Motors is working with GS Yuasa.
The 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. Cumulative sales have topped one million units worldwide.
Toyota has a goal of selling at least one million hybrid cars a year in the early part of the next decade by offering the fuel-saving system on more vehicles.
