Sunny Side Up Edition 6 | September 2025
A massive congratulations to all the teams who recently competed in the Bridgestone World Solar Challenge (BWSC) in Australia! From the blazing Outback heat to the endless straight roads, every team showed remarkable innovation, resilience, and determination.
This year’s BWSC saw record-breaking efficiency, new designs that pushed the limits of aerodynamics, and the next generation of student leaders stepping into the spotlight. With cars averaging over 90 km/h powered only by the sun, the event once again proved the future of mobility is bright.

Each edition of the Sasol Solar Challenge pushes the boundaries of what solar mobility can achieve. But it’s not just about solar cars — it’s about endurance, engineering, strategy, and heart. This is where innovation meets Africa’s vast terrain — where global teams challenge themselves against more than the road ahead.

Not all solar car events are created equal.
While some follow fixed routes and rigid formats, the Sasol Solar Challenge dares teams to think bigger. To compete here, you’ll need more than a well-built car. You’ll need strategy, endurance, adaptability, and discipline — all tested in real-time on public roads.
