Should automakers prioritize hydrogen-fueled combustion engines over electric battery technology for future vehicles?

Toyota and MissionH24 are developing a 3.5-liter V6 hydrogen combustion engine for the H24EVO project, announced on September 26, 2026. This initiative aims to produce 871 horsepower for high-performance endurance racing without traditional fuel cell hardware.

Why it matters

The project seeks to eliminate fossil fuel reliance while maintaining the familiar architecture and performance characteristics of internal combustion engines. By avoiding heavy fuel cell systems, engineers aim to achieve a competitive vehicle weight of 1,250 kilograms for endurance racing.

The H24EVO utilizes a 3.5-liter V6 hydrogen combustion engine paired with a hybrid electric drive. The design targets a maximum speed between 199 and 205 mph to compete in international racing circuits.

The players

Toyota

A global automotive manufacturer known for pioneering hybrid electric vehicles and pursuing diverse alternative-fuel powertrain solutions.

MissionH24

A collaborative racing initiative focused on developing high-performance hydrogen-powered vehicles for endurance events.

FORVIA

A major automotive technology supplier providing the cryogenic tanks required for hydrogen storage in the project.

The details

The system replaces traditional gasoline with hydrogen through an internal combustion process that interfaces with a standard mechanical transmission. By integrating a hybrid system, the powertrain compensates for the unique combustion properties of hydrogen to deliver high power output. This setup avoids the weight and complexity of hydrogen fuel cell hardware, which typically requires large stacks and specialized cooling systems.

Timeline

  1. September 26, 2026: H24EVO project announcement.

  2. Early 2028: Planned official reveal of the vehicle.
