OYAMA, Shizuoka Prefecture--Toyota Motor Co.’s car powered solely by a hydrogen engine became the world’s first to complete a 24-hour endurance race, the automaker said.

The Corolla H2 Concept vehicle, remodeled from a Corolla Sport, entered the Super Taikyu Series endurance race on May 21-23 at the Fuji Speedway track here.

Using the racing circuit as a testing ground, the auto giant plans to heighten technological developments for decarbonization.

Hydrogen engines have a similar mechanism to those of gasoline engines, but burning hydrogen creates almost no carbon dioxide.

Toyota’s vehicle was installed with four fuel tanks that can contain 7.3 kilograms of hydrogen in the backseat.

The automaker converted an engine for the commercially available GR Yaris sports car and equipped it with a hydrogen injection system.

“We will increase options for decarbonization technologies,” said Toyota President Akio Toyoda, who also served as a driver in the endurance race. “And we have just taken the first step.”
