Bridgestone 2027

With 2025 in the rearview, we look to try and compete in the 2027 Bridgestone World Solar Challenge

The Bridgestone World Solar Challenge is the most prestigious solar car challenge, held every two years. The race runs 3000 km (around 1850 miles) from Darwin to Adelaide through the Australian Outback. The race usually takes between 4 and 6 days and is typically done by collegiate teams. While the schedule for the 2027 Challenge is not released yet, typically it is held sometime between July and October.

We are currently constructing a new car for this race, and hope to make it to Australia in 2027! This will be a huge step forward for our team, and by far the hardest thing we have ever attempted.

As we build we will be regularly posting updates on our blog (tab on this website) and our Instagram.

Stay tuned on our progress!

In summer 2025 we took our fifth title with our newest car, Ember. This car redefined what perseverance meant for our team, designing and building this composite car in just four months. Despite the constraints and challenges, this rocket ship of a c
In 2024 we finally got to bring Sockeye to competition in Texas. Sockeye at this point was the most sophisticated car we’d built: our first carbon fiber car, our most advanced solar array, and our best electronics. Sockeye, though, was built to
2022 was the year things finally came together perfectly. The improvements we had made over the build season allowed Jimmy to run even faster, but most importantly, we had built a good support system within the team. The race for us this year was an
2021 was the year our team learned resilience. Coming off of a win in 2019, we were excited for the new year. Despite the pandemic, shipping issues, and so many problems on every single system on the car, we still managed to put together a solid car
Our first race! With so much to learn, this year was a full sprint for us. 2019 was a year all about the basics of solar racing, from chassis construction and aerodynamics, to an incredibly useful strategy system. 2019 would set the groundwork for ou
As we prepare for something new, we’ve been looking through our old notes and races. This week we will be sharing about each of our five cars and what we learned, one per day this week. This Saturday, we will be releasing our newest plans, an
Last Thursday we got to showcase at the @museumofflight down by Boeing Field during their First Free Thursday event (free admission to the museum on the first Thursday of the month!). Got to meet so many amazing people and had a really great time. Th

Frequently Asked Questions

  • The Bridgestone World Solar Challenge is very different from The Solar Car Challenge in many ways. For us the biggest differences include much stricter rules around quite literally everything on the car, most notably safety and an extreme focus on efficiency. In addition, the teams that usually compete here are University level or higher teams. Finally, the logistics and scale of operations is vastly larger than what is found in events based on our own continent.

  • After five races in The Solar Car Challenge, we’ve pushed our own technology beyond what we thought was possible. After the 2025 race, when deciding what to do going forward, we thought that attempting a new challenge would be most beneficial for our teams learning and growth, and we also thought that a brand new adventure has some amazing possibilities.

  • This car has to be the best we’ve ever built, no questions asked. We plan to build another fully composite car, and have been working behind the scenes for months to better simulate and test aerodynamics and structural safety. Additionally, we’ve been working toward quite a few things with our electronics and strategy teams, although that will have to remain a secret for now…

  • Ember remains in service with the team as a show and test vehicle. While the mechanical structure will remain unchanged for this role we will continue to replace the electrical systems in order to test components for our new car.

  • We are always looking for many things, not limited to people people excited to support us, sponsors looking to partner, or dedicated new team members. if you fit any of these, or simply want to get involved or learn more, please contact us via our email or this website..
