Toyota has long been among the strongest proponents of hydrogen as a power source, and has now showcased its experimental hydrogen combustion engine technology in the GR Yaris, in which its G16E-GTS turbocharged 1.6 litre three-cylinder engine has been adapted to use hydrogen as fuel.
The internal combustion engine from the high-performance three-door hatchback employs a modified fuel supply and injection system, while the hydrogen fuel, tanks and refuelling process are the same as that for the commercially available Mirai, which generates energy through a chemical process in its fuel cells.
This hydrogen-powered engine configuration has already seen deployment in the Corolla Sport that has been entered into the Super Taikyu racing series in Japan, under the Rookie Racing banner of the Toyota Gazoo Racing team to test the setup under the pressures of motorsport.
