Hydrogen-powered Toyota GR Yaris concept revealed

The combustion-powered Toyota GR Yaris has been fitted with a hydrogen fuel system in this latest concept car.

While many of us will be familiar with electricity-generating hydrogen fuel cells as a route to lower emissions vehicles, the fact that hydrogen can be burnt in combustion engines usually gets less attention. This technology theoretically has the potential to combine zero carbon tailpipe emissions with the desirable performance characteristics of a petrol engine, and Toyota is exploring it with this new GR Yaris concept.

In order to run the GR Yaris on liquid hydrogen, few of the car’s internals have had to 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 that have been made only focus around the fuelling system, swapping the standard fuel tank for a highly-insulated pressurised tank and modifying the fuel rails and injectors to suit.

Looks like the hydrogen tanks have occupied a large volume of the rear of the yaris. One of the major hurdles to eliminate.

Not so easy. However still not impossible.

So is this a win-win, right? Well not exactly. Hydrogen combustion technology hasn’t been widely adopted by all manufacturers for a variety of reasons, starting with the fact that while it’s light on carbon, it still produces nitrous oxide (NOx) at relatively high levels.

while the car itself has no co2 emissions but the hurdle of NOx emissions remain.

The dream scenario of fixing all of the combustion engine’s problems with a simple switch to hydrogen doesn’t seem to work out, yet. But that’s not to say the current flaws in the technology won’t one day be solved.

Thanks!

  • It seems like an interesting development. I don't know enough about it to say whether I support it or not, but it looks better than EVs. I think it produces about 20% less power than a normal ICE, which is an issue, but we'll see what happens with it.

  • Well this is a huge win for ICE, I would hope that they continue too test it and possibly do what Handa did with the original Clarity so we could test it ourselves

  • Dont get excited this is probably not going to make it in production.
