Toyota Motor Corp. said that it had developed a new zero-emission fuel-cell vehicle that has a longer cruising distance than previous models and can operate in freezing temperatures. Japanese companies have been working to create a viable zero-emission car running on fuel cells, which produce electricity through a chemical reaction between hydrogen and oxygen, leaving water as the only by-product.

Toyota's system "was enhanced to further improve cruising distance and low-temperature starts, which had presented obstacles to widespread fuel-cell vehicle use. Toyota engineers managed to control the amount of water produced inside the fuel-cell system, which previously interfered with electrical generation at low temperatures. Fuel efficiency was also improved.

Toyota announced that it would continue to strive to improve the durability and reduce the cost of fuel-cell vehicles to bring about their widespread use. Besides the hefty price, motorists would also need an infrastructure of hydrogen filling stations if they are to take the cars on the road. Toyota was a pioneer of petrol-electric hybrid cars which are attracting growing interest at a time of soaring oil prices and increasing concerns about global warming.
