Toyota fitted a racing Corolla with a GR Yaris engine modified to run on hydrogen.
After helping to democratize the hybrid in the early 2000s, Toyota has been working for a few years to do the same with hydrogen . One thinks in particular of the large Mirai sedan , of which the second generation was recently launched. This car uses hydrogen in a fuel cell : hydrogen is converted into electricity, which powers an electric motor. In short, an alternative to the battery car .
But this technology is not the only way to use hydrogen in the automobile. Highly flammable, this gas can also be used as a replacement for gasoline or diesel in a conventional internal combustion engine. Certainly, some adjustments are necessary, and the energy efficiency is lower than that of conventional oil, but the game can be worth the candle: the whole thing only releases water vapor, and no CO2 , while maintaining the characteristics. a thermal engine that enthusiasts will appreciate.
The GR Yaris engine in a racing Corolla
Toyota therefore decided to explore this technology, in the always demanding context of motorsport. To do this, a small 3-cylinder turbo Toyota GR Yaris engine was converted to hydrogen, and installed under the hood of a racing Corolla . This car will be entered in an endurance race in Japan at the end of May. A real test for technology, with hydrogen refueling scheduled during the event.
Toyota is not, however, the first manufacturer to attempt the hydrogen adventure in racing: in 2013, a hydrogen-powered Aston Martin Rapide took part in the 24 Hours of the Nürburgring.
