Toyota today showcased its experimental hydrogen-powered combustion engine technology in the multiple award-winning GR Yaris.

The hydrogen fuel, fuel tanks and refuelling process of the experimental vehicle are the same as found in the Mirai, Toyota’s commercially available flagship fuel cell electric vehicle.

However, whilst the Mirai employs chemical reaction in the fuel cells to generate energy, the experimental GR Yaris features an internal combustion engine with hydrogen as the fuel.

While the hydrogen combustion engine technology is still in the early stages of conceptual development and experimentation, which started in 2017 and not yet ready for commercialisation, Toyota’s experimental hydrogen-powered Corolla Sport is already delivering high performance at motorsport events in Japan with almost zero tailpipe emissions.
