Support Us

The Principia College Solar Car Team is moving forward in anticipation of racing this summer in the 2023 Formula Sun Grand Prix. So far, the race is still on, and we will do whatever it takes to be ready!

We are still working to build the new car, Ra XI, for the race. Keep up with our progress by following our Facebook page.

Funds contributed in the past have enabled us to make significant progress on the car’s construction (frame, array, batteries, molds etc.) and to prepare for the race despite all the challenges thrown at the team in the last year. The current situation challenges us to be even more innovative, collaborative, and resourceful than before.

Making a gift in support of the Solar Car team will help us to afford the tires we need for our pit stops, pay for our race entry, cover the travel, lodging, and food costs during the race, and much more.

We look forward to putting our skills to the test and making Principia and our family of supporters proud. One thing you’ve probably seen and heard a lot recently is true—we’re all in this together!
