Tshwane University of Technology’s Sunchaser 4 made history after becoming the first South African team to win the Sasol Solar Challenge.
The team also became the first local team in the challenge’s history to complete the newly designed full route unassisted. The final morning of the 2026 challenge began in Clanwilliam, with the Cederberg mountains providing a spectacular backdrop.
But the beauty came with a price. The mountainous terrain made battery charging difficult, while the steep climb towards the control stop in Ceres tested the teams and their solar-powered machines.
Yet, as the finish line drew closer, something unexpected happened. Teams that had spent weeks protecting their hard-earned technology secrets began opening up.
Battery strategies, aerodynamic tricks and other engineering ideas were shared between competitors. Rivals became friends.
And the spirit of teamwork grew stronger as the teams travelled towards the finish. But one team stood out.
TUT’s Sunchaser 4 was the only car to reach the Ceres control stop without a trailer. The team carried that momentum all the way to Franschhoek.
By the time the dust settled, TUT had topped both the daily and overall leaderboards. The team covered a massive 2 369.2km.
Switzerland’s Solar Energy Racers finished second after covering 1 518.3km, while India’s AgniRath took third with 1 191.6km.
For TUT, however, the victory was about more than a trophy. It was a breakthrough moment for South African engineering, renewable-energy technology and the continent’s young innovators.
The challenge also ended with a powerful lesson. The teams had started as competitors, fiercely guarding their ideas and technology, but ended as friends.
