How Toyota's Hydrogen Combustion Engine Could Make EVs Obsolete
Let's talk Toyota, hydrogen fuel cells, hybrid and plug-in hybrid vehicles, the current electric vehicle craze, and the future of ICE.
Toyota's Newest Hydrogen Engine
Toyota
Toyota has once again pushed the boundaries of automotive innovation with its newest hydrogen engine. Among the standout features of this new technology is a 1.5-liter engine available in both naturally aspirated and turbocharged versions, along with a 2.0-liter turbocharged unit. These engines are designed to be 10 to 20 percent smaller than their predecessors, yet they deliver the same or even better fuel efficiency and performance. What makes these engines truly revolutionary is their ability to run on a variety of carbon-neutral fuels, such as synthetic e-fuels, biodiesel, hydrogen, and gasoline.
This versatility, combined with their compact size and low emissions, makes them ideal for integration with electrified hybrid systems. This marks a significant step forward in the automotive industry’s quest for greener solutions. As Toyota continues to refine this technology, we can expect more detailed specifications and further advancements in the coming years, particularly as the Euro 7 emissions standards come into effect in 2027.
Hydrogen Engine Efficiency
One of the most remarkable aspects of Toyota’s new hydrogen engines is their enhanced thermal efficiency. Thermal efficiency measures how effectively an engine converts fuel into usable energy rather than losing it as heat. Toyota’s extensive research and development, particularly through its experience in hydrogen combustion on the race circuit, have led to significant improvements in this area. The leanest engines today achieve thermal efficiency rates above 40 percent, but those designed for hybrid setups can reach up to 50 percent.

While exact figures for Toyota's new engines are not yet available, the company has indicated that the 1.5-liter naturally aspirated engine will surpass the efficiency of its current gasoline-powered counterpart, and the 2.0-liter turbo will outperform the existing 2.4-liter turbo. These advancements are not just about reducing emissions but also about improving overall engine performance. This is a crucial development, especially as the automotive industry faces increasingly stringent emissions regulations and a growing demand for cleaner, more efficient vehicles.
Smaller But Mightier
Toyota’s new engines are not only more efficient but also more compact. Engineers achieved this by implementing a shorter piston stroke, a significant departure from traditional engine design which favors longer strokes to maximize air and fuel intake. The engine's revolutions per minute were also reduced, thereby improving efficiency and reducing the overall size of the engine.
The downsizing allows for more streamlined vehicle designs, with the potential for lower hoods and more aerodynamic body styles. Despite their smaller size, these powertrains do not compromise on power. By leveraging hybrid technology, where electric motors can compensate for reduced torque, Toyota ensures that the new engines deliver a robust performance. As these engines make their way into the market, they are set to become a cornerstone of Toyota's strategy to lead the industry toward a greener and more efficient future.
