Extreme H has completed the production run of its race car, the Pioneer 25, which replaces the Odyssey 21 that has been utlilized by the series’ predecessor Extreme E for the last four years.

Ten of the hydrogen fuel cell cars have been built by manufacturer Spark Racing Technologies just outside Paris, France, following an intensive testing program in the southwest of the country and Scotland, in which the equivalent of three full seasons-worth of racing mileage has been completed so far. Among the test drivers to have worked on the car’s development have been Le Mans winner and pikes Peak record holder Romain Dum as, and Extreme E regulars Hedda Hosaas, Timmy and Kevin Hansen, and Catie Munnings.
