15: Western Sydney Solar Team

The Western Sydney Solar Team has competed in five official events, starting with the 2013 Bridgestone World Solar Challenge, followed by 2015, 2017, 2019, and 2021. Although the 2021 event was cancelled due to COVID-19, we returned in 2023, finishing 9th in the world.

Unlimited 6.0 is an evolution of our previous car, refining nearly every aspect to create our most aerodynamically and electrically efficient vehicle yet. Built on a three-wheeled monohull design, our philosophy prioritises aerodynamic performance, energy efficiency, and, most importantly, reliability. Every decision, from the lightweight structure to the optimised solar array, focuses on maximising performance while ensuring the car can withstand the demands of the challenge. Our team continuously pushes the boundaries of materials, aerodynamics, and energy management, aiming for our best-ever result on the world stage.

Unlimited 6.0 is the most aerodynamically efficient sealed solar car we’ve ever built. By refining the fitment of the array and fairings and optimising the design of wheel covers, we’ve taken aerodynamic performance to an entirely new level. One of the most unique innovations is our completely wireless steering wheel, enhancing efficiency while reducing weight. We’ve also optimised both battery and solar cell packing efficiency to maximise energy output. Furthermore, our ultra-lightweight paint improves aerodynamics without compromising finish quality. Taking full advantage of new ride-height regulations, we’ve integrated aero devices in front of each wheel to precisely sculpt airflow.

The Bridgestone World Solar Challenge is an opportunity to showcase our innovation and demonstrate what a 100% student-led project from Western Sydney can achieve. It pushes us to the limits of engineering, efficiency, and teamwork, proving that we can compete on the world stage. This event is more than just a design challenge, it's a platform for collaboration, problem-solving, and pushing the boundaries of what’s possible in solar vehicle technology. The challenge unites our team, fostering skills and experiences that will shape the next generation of engineers and innovators.

As an Australian team, we like to think we have a home advantage—but racing 3,000 km through the Outback challenges everyone! We’re excited to push solar technology, compete with the world’s best, and represent Australia. The Bridgestone World Solar Challenge is the ultimate test, and we can’t wait.
