Ecoticias writes that the new type of fuel used by Toyota in this development is not new at all, as it is the hydrogen that the company already used in one of its models, the Mirai. However, instead of hydrogen powering an electric motor as it is the case for the existing car, it will be adapted to run on an internal combustion engine, releasing only water vapors, instead of CO2 and other emissions.

Still, why develop hydrogen internal combustion engines, when the company already has a hydrogen electric model? Well, it's because the performance in the Mirai isn't all that great, with the car's hydrogen electric motor outputting only 182 horsepower, while the new hydrogen internal combustion version is capable of up to 400 HP. And Toyota also might look at more variation in the market for this technology.

At the same time, the company's new hydrogen ICE engines have a thermal efficiency of up to 45%, which rival the most efficient diesels on the market. The Japanese company will use its knowledge from the development of hydrogen fuel cells to design suitable ICE hydrogen engines for passenger and commercial vehicles.
