Toyota New H2 Engine

Explore the 2025 Toyota Mirai which combines hydrogen with oxygen from the outside air to generate power, without creating tailpipe emissions. The Toyota Corolla Cross H2 Concept uses a new prototype hydrogen Internal Combustion Engine (abbreviated "ICE") car called the Corolla Cross H2 Concept. The company has unveiled the Corolla Cross H2 Concept, equipped with an internal-combustion engine designed to burn hydrogen instead of gasoline or diesel.

It's not just any combustion engine, either. Toyota is moving forward with hydrogen combustion technology, unveiling a new prototype designed for future competition in the 24 Hours of Le Mans. At a press conference of the Automobile Club de l'Ouest (ACO) at Circuit de la Sarthe in western France on June 9, Toyota Motor Corporation Chairman Akio Toyoda revealed for the first time the hydrogen engine vehicle prototype "GR H2 Racing Concept".

Toyota's latest breakthrough in sustainable mobility - the world's first water engine. Departing from conventional hydrogen-powered vehicles, this groundbreaking innovation operates at an unprecedented temperature of 2500°C, thanks to its ingenious water-cooled design. But that's not all - equipped with a special dual injection system, this engine delivers unparalleled efficiency and performance.

This innovation builds on Toyota's deep expertise in hydrogen fuel cell technology, honed over years of research and product development. With this new internal combustion design, Toyota may bridge the gap between traditional engines and fully electric powertrains, offering yet another route to sustainable transportation. In 2023, the hydrogen-engine Corolla completed a demonstration lap of the Circuit de la Sarthe, while a hydrogen engine concept car, the GR H2 Racing Concept, was presented to preview a potential future hydrogen category at Le Mans.

Toyota's engineers equipped the 1.6l 3. Toyota has been working on hydrogen technology for a long time now, and here's everything you need to know about its hydrogen combustion engine.
