MAZDA will use Japanese fleets to help develop the world’s first ‘street-legal’ hydrogen-fuelled rotary engine car over the next few years.

Japan’s transport authorities have given Mazda permission to test the dual-fuel car that will run on petrol or hydrogen and in the next two years will lease the car, known as H2RE, to government and fleet users as a feasibility study for the powertrain.

When running on hydrogen, the engine produces no carbon dioxide emissions and near zero nitrous oxide emissions.
