Mazda test drives hydrogen hybrid vehicle

apanese car maker Mazda had begun testing a hydrogen/petrol hybrid vehicle on public roads.

The Premacy Hydrogen RE Hybrid minivan has a range of 200km on hydrogen fuel, which increases to 550km when running on petrol. The 4.5 metre-long vehicle can hold five passengers.

"We will continue to advance our development programme and strive to start commercial leasing during this fiscal year," said Akihiro Kashiwagi, Mazda's programme manager in charge of hydrogen RE development.

The vehicle is powered by a hydrogen rotary engine, which can run on hydrogen and petrol, and an electric motor. The driver can switch between the two fuel sources by pushing a button.

Hydrogen is stored in a high-pressure tank, while a generator is used to charge lithium-ion batteries which power the electric motor.

From information released by Mazda, it is not clear whether the rotary engine can drive the Premacy's wheels directly.
