Experimental Hydrogen Powered Toyota GR Yaris Revealed
Toyota has revealed a new prototype GR Yaris driven by experimental hydrogen-powered combustion engine technology.
The vehicle shares the same hydrogen fuel, fuel tanks and refuelling process as that of the Mirai, Toyota’s commercially available flagship fuel cell electric vehicle (FCEV). However, whilst the Mirari employs chemical reactions in the fuel cells to generate energy, the experimental GR Yaris features an internal combustion engine with hydrogen as the fuel.
In order to run on liquid hydrogen, a few of the internal features must be modified. The concept uses the same G16E-GTE turbocharged 1.6-litre three-cylinder engine, six-speed manual transmission and clever all-wheel-drive system as the petrol version. The changes focus on the fuelling system, swapping the standard fuel tank for a highly insulated pressurised one. The fuel rails and injectors are also modified to suit.
Hydrogen combusts at a faster rate than petrol, resulting in good responsiveness while delivering excellent environmental performance. Toyota hopes to create an eco-friendly alternative that shares the acoustic and sensory sensations that characterize an internal combustion engine.
The technology is still very much in the early stages and is not yet ready for commercialization.
“Towards achieving carbon neutrality, Toyota has been strengthening its efforts, such as by aiming to promote the use of hydrogen through the popularization of FCEVs and numerous other fuel-cell-powered products,” the company wrote.
“By further refining its hydrogen-engine technologies through motorsports, Toyota intends to aim for the realization of an even better hydrogen-based society.”
