Japan, Tokyo

Toyota Motor Corp said on Friday it has developed an advanced fuel-cell vehicle that can run for 830 km (516 miles) on a single tank of hydrogen and in temperatures as low as 30 degrees Celsius below freezing (-22 F). The new version of the fuel-cell car, which runs on hydrogen and emits only water, increased fuel efficiency by 25 percent with an improved fuel cell unit and other changes to its brake system and elsewhere. The zero-emission FCHV-adv will be leased to government agencies, among other possible users, in Japan starting later this year, a spokeswoman said.

Combined with a slightly bigger fuel tank and a doubling of the maximum storage pressure, the FCHV-adv extended the cruising range from the previous FCHV's 330 km (205 miles), Toyota said in a statement. It has a maximum speed of 155 km per hour (97 mph).

According to the Reuters report Toyota's FCHV-adv will be showcased as a test-ride vehicle at the Group of Eight rich nations' summit in Toyako, northern Japan, next month. It will also provide more than 70 hybrid cars and hydrogen-fuelled buses for use by shuttle participants.
