Toyota’s recent efforts in dominating the car industry have been quite prosperous for the company. 

They’ve already kick-started a whole market and industry branch with their hydrogen cell-powered cars, which are becoming increasingly popular. 

However, Toyota has also started developing a new way of using hydrogen in vehicles, and that’s by making an internal combustion engine that uses hydrogen combustion engine as fuel.

How does this engine work, and what’s the main motive for Toyota to make it? 

Is it better than what Tesla currently has? Join us as we take a look at Toyota’s all-new hydrogen combustion engine that shocked the entire car industry.

Toyota has been a key player in electrifying vehicles, and they’ve been the leader when it comes to innovating the whole car industry. 

The Toyota Prius is the best-selling hybrid of all time. And it was the car that kickstarted the whole electrified vehicle craze, which in turn led to the accelerated development and rise of customer interest in fully electric vehicles. 

Toyota had decided in the past that they’ll stick to their hybrid and traditional vehicles for as long as they can. 

Toyota had only recently entered the EV segment with its Toyota BZ four X and the CEO of Toyota Akio.

Toyota even said that he doesn’t truly believe that the EV segment will beat out hybrids and traditional internal combustion engines anytime soon. 

You can learn more about that by clicking on the right top corner. Now, anyhow, Toyota has been developing its alternative to EVs and that’s a fuel cell electric vehicle, or as they’re popularly known, hydrogen cell powered cars (hydrogen combustion engine).


  • The primary benefit of FCEVs is the fact that they’ll be using the most abundant element in the entire universe. 
  • Fuel cell electric vehicles don’t pollute as many EVs during their production process as the batteries used in hydrogen cell-powered cars are much weaker and require less lithium than typical EVs. 
  • On the other hand, they don’t pollute while being used as IC engines do, as they are in essence EVs. 
  • The original Toyota Marai is considered a technological marvel when it came out back in 2014.

It’s not planning to be produced in huge numbers, as it was technically an exclusive for the Japanese market. 

California was so popular that Toyota spawned a second generation in 2020 that has also been released worldwide. 

The X Top Gear presenter James May even owns one. Apart from Toyota, many other companies starting to make FCEVs like the Honda Clarity and Hyundai Nexo. 

Also, many other automotive giants like Volkswagen, BMW, and Mercedes announced that they too plan to produce their hydrogen cell-powered cars. 

However, Toyota had recently started developing a technology that could use hydrogen (hydrogen combustion engine) in more efficient ways. 

As her recent ventures into converting internal combustion engines into using hydrogen as its propellant turned out quite fruitful for the company.

Engine Specification

Toyota has recently converted their beloved six turbocharged three-cylinder engines found in the Toyota Corolla Gr and the Toyota Yaris Gr into using hydrogen instead of typical fossil fuels. 

Not only that, but they’ve also started a joint venture with Yamaha to produce a hydrogen-powered 50-liter V Eight (hydrogen combustion engine). 

How does an internal combustion engine that runs on hydrogen function? 

Well, you’d be surprised to find out that the hydrogen combustion engine functions rather traditionally.

It’s similar to the vehicles that run on compressed natural gas instead of petrol. A huge tank that is much thicker than your typical fuel tank holds the hydrogen in place. 

Hydrogen is a highly flammable gas, and a de facto armored tank is needed so that the hydrogen doesn’t escape. 

The engine requires hardened valves and valve seats, stronger connecting rods, and fuel injections that are designed for gas instead of liquid. 

A bunch of other improvements and general strengthening of the hydrogen combustion engine components so that it can withstand a higher overall pressure in the cylinder.


  • The overall usage of hydrogen is nearly identical to the usage of standard fossil fuels. However, there are no CO2 emissions compared to them. 
  • Another plus for hydrogen engines is that their engines produce similar amounts of horsepower to their more-traditional counterparts. 
  • Also, the refueling time is low compared to EVs, as it only takes 1.5 minutes for the new Yaris Gr H Two to be filled to the Brim. 
  • So overall, these vehicles could be the way of the future. And if you ask us, we see them becoming more popular in the upcoming years.

How will these cars exactly make EVs and FCEVs go extinct? 

  1. These cars are way more practical than EVs and FCEVs, as they have a higher range and are much faster to refuel. 
  2. The other benefit is the fact that they’re completely mechanical, which means that they could be repaired and not simply discarded.

The technology of processing hydrogen 

A major plus is that these vehicles don’t need unrenewable resources to run, unlike fossil fuel cars, or to be manufactured, which makes the whole production and usage both much more green and completely sustainable. 

Also, let’s not forget the part that refueling these vehicles could become cheap once Huaida conquers the technology of processing hydrogen (hydrogen combustion engine). 

Let’s not forget that these cars are fun to drive. The driving experience is almost identical to a traditional vehicle, which includes key things that petrol heads love about IC engines they make a noise. 

Have you heard of the 163-cylinder? 

It’s a beautiful little symphony. And its hydrogen-powered cousin makes an as good noise and in our opinion, even better than the petrol-powered version.


Fabulous. Imagine what a 50 V Eight would sound like. As their upcoming hydrogen combustion engine is said to produce around 450, it will rev up to 6800 rpm. 

It’s also going to be a fantastic engine overall. I mean, the legendary Two JZ was code developed by Yamaha, and so was the fabulous V Ten found in the Lexus LFA.

We go ahead and write off EVs and traditional vehicles completely, there are a few things that need to be noted and a couple of problems concerning hydrogen as a propellant. 

  • Toyota isn’t the first car to make a hydrogen-powered IC engine. 
  • These vehicles are made in the past and the most successful ones prior. 
  • Toyota was BMW back in 2002 with the BMW 750 HL. And later in 2005, they introduced the Hydrogen Seven. 
  • Both cars are flooded with numerous problems that are still found in hydrogen internal combustion engine vehicles.
  • That hydrogen is flammable and even explosive in some cases, which would make it a huge safety hazard.

It’s hard to process and even harder to store. And even though CO2 emissions don’t exist, the high combustion temperatures emit huge amounts of nitrous oxide, which is also a pollutant. 

That can be reduced by doubling the amount of air needed for complete combustion, which then makes the car significantly weaker than its petrol-powered counterpart.

That means that the hydrogen combustion engine need to be huge to make sufficient amounts of horsepower, which would effectively mean a thirstier engine. 

The highly complicated way of processing and storing hydrogen makes it more expensive than petrol and diesel. 

The current tech also makes these cars way less economical. Finally, the production process is at least one and a half times more expensive than making a traditional IC engine, because the hydrogen engine needs to be much more durable.


Currently, the best use of hydrogen internal combustion engines is using it in a hybrid, as it noticeably reduces nitrous oxide emissions and increases the fuel economy at least until the technology gets more advanced. 

So, as much as we’d like to see cars such as Toyota Yarisgrh Two flood the market as soon as possible, it’s not going to happen anytime soon due to technology restrictions. 

However, we do believe that further development of this idea could turn very profitable for Toyota in the long run. 

We do believe that hydrogen-powered internal hydrogen combustion engine will become a viable option in the future.
