Spark Racing Technology announced Thursday that it has completed production of the ten Pioneer 25 cars that will contest the inaugural Extreme H season this year.

“This project has pushed the boundaries of hydrogen technology in motorsport, combining advanced engineering with sustainable innovation,” said Spark chairman Nicolas Wertans. “We believe these vehicles will set a new standard for hydrogen-powered competition and inspire the future of clean energy solutions.”

The AWD, dual-motor Pioneer 25 is the successor to Extreme E’s Odyssey 21, also built by Spark. It is longer and heavier than the Odyssey, has its driver seat in the center rather than on the side, and uses a 75 kW hydrogen fuel cell instead of a battery. Like what Chip Ganassi’s GMC Hummer EV partnership did for the Odyssey, the bodywork can be modified to resemble production cars.

The fuel cell was developed by Symbio and connects to a 325-kW battery from Fortescue ZERO. With the hydrogen system, the Pioneer 25 can reach 100 km/h in 4.5 seconds at maximum output of 400 kW (550 horsepower). The use of hydrogen means the only emissions from the car are water vapor.

Unveiled last June, the Pioneer 25 underwent its first test in December 2023 before test driver Hedda Hosås drove it around the Hydro X Prix course last summer.

“The production of our ten car race fleet marks a major milestone as we move closer to the launch of the FIA Extreme H World Cup,” added series CEO Alejandro Agag. “These cars are not just groundbreaking in terms of technology; they represent the future of sustainable motorsport, and we are ready to go.”

The series received the World Cup designation from the FIA in December.
