Mazda has unveiled the world's first ‘on-road’ dual-fuel hydrogen rotary H2RE – the RX-8 Hydrogen RE.

Japan's transport authorities recently gave Mazda permission to road test the hydrogen-fuelled, rotary-engine version of its head-turning Mazda RX-8 sports coupé.

The new vehicle features a dual-fuel system that allows the driver to select hydrogen or gasoline with a flick switch.
