Toyota GR Yaris H2: Hydrogen three-cylinder for the Hot Hatch

Toyota continues to work on the Hydrogen technology. The Japanese only presented a hydrogen engine for racing in April 2021, now the unit is also to be installed in a GR Yaris for test purposes. With the Experimental engine However, the Japanese are not relying on a fuel cell – instead, the hydrogen is burned in the engine like gasoline.

At there are inexpensive new cars, including the Toyota Yaris.

In contrast to the Mirai, Toyota does not use a fuel cell for the new test engine. The hydrogen becomes conventional burned; there is no chemical process in which electrical energy is generated from combustible gas and oxygen. The basis for the internally named GE16-GTS racing engine is the 1.6-liter three-cylinder from the Toyota Yaris GR. In the production vehicle, the engine has an output of 261 hp. However, Toyota has not yet disclosed what it will bring to the test after the hydrogen treatment.

In the Toyota GR Yaris, the 1.6-liter three-cylinder has an output of 261 hp. There is no data on hydrogen operation.

Because of the different characteristics of the hydrogen compared to gasoline are on the engine Adjustments in the area of ​​the fuel supply and the injection system are necessary.

Without any notable success, however, because the 100 vehicles produced were not sold, but some were handed over to celebrities on a leasing basis. Despite everything, the development of such engines continued. So far, the technology has mainly been in the Truck and bus sector on response. So far, the fuel cell has established itself as a common means in passenger cars.
