Returning to Fight
for the Title

From September 19 to 20, 2026, we return to Circuit Zolder for the world's only 24-hour solar car race. Following our 2022 championship and our podium finishes in 2024, we are ready to push sustainable mobility to its limits once again.

Our Solar Cars on Track

To maximize our strategic potential and fight for the top spots in the Challenger Class, we are entering the 24-hour race with two of our custom-built solar cars. Racing both vehicles simultaneously allows us to pit two generations of our engineering against each other and double our chances on the track.
