This summer, Toyota decided to start hydrogen racing. The company has, after all, invested heavily in the hydrogen ecosystem. However, this time the difference is that instead of using hydrogen in the fuel cell, the Corolla Sport was burning in the combustion engine. It wasn’t necessarily the most efficient way to do it, but, according to its announcement on Thursday, it did not stop Toyota.
Now, Toyota is expanding its hydrogen race car program to include the much-loved and ultra-tough GR Yaris. Fortunately, instead of switching to a foreign power train to switch to hydrogen, Toyota engineers modified the three-cylinder turbocharged engine that GR Yaris already had.
So, if burning hydrogen for fuel is not very efficient, why do it in a race car? Voice, friends. Noise Many car enthusiasts – even people like us at road shows who like electric cars – regret to push the sound of internal combustion engines to their limits. Burning good, clean hydrogen allows racing to retain that sound while also being almost completely free of emissions. Is it practical for everyday road use? No, at least not yet, but we like where Toyota is going with it.
Now, we’ve found that the Hydrogen GR Yaris engine has been modified, but of course, if you’re going to use hydrogen as a fuel source, your regular gas tank won’t work. Fortunately, the hydrogen storage tanks used in Mirai and the equipment needed to fill them will work just as well.
We’ve already talked about hydrogen being a clean burning fuel, but another feature that makes it attractive in combustion engines is the rate at which it burns. The combustion properties of hydrogen differ from those of slow-burning gasoline. This increases the tuning of the engine and the response from the engine, which Toyota is taking advantage of in its Super Tyco Corolla Sport race car.
There’s something to be seen in the production car, let’s face it, perhaps given the already challenging infrastructure issues of using hydrogen as fuel, but that doesn’t mean the idea isn’t cool and we Can’t find the root. For it. In fact, we really expect Hyundai’s other big players to join the fun.
