Track Day 18th March 2025
Today’s track day was held at Jamberoo Action Park, with the main goal being to figure out what’s been causing recent issues with our accumulator. Another key aim was to test how reliable the setup would be when the car was put through the stress of real driving conditions, giving us a clearer idea of how the system performs.
We arrived at the track around 8:00 a.m. and began running the car not long after. The early sessions were all about ensuring that everything was functioning as expected and there were no immediate faults. The driver was instructed to push the car with quick turns, hard braking, and fast acceleration to really shake things up. After every run, the accumulator was checked carefully for errors and inconsistencies.
By late morning, some smaller problems began to appear. The system responsible for connecting and disconnecting the accumulator started behaving inconsistently, which raised some concerns. While the issue didn’t cause a complete stop to the day, it did highlight that further investigation is required. Eventually, the car began running more reliably again, but the team members of High Voltage will need to open the accumulator and take a deeper look to make sure the issue is fully resolved.
We also received some useful feedback for our suspension system. Our experienced driver noticed a few things that weren’t quite right in the handling of the car. While the issues weren’t major enough to halt the day’s testing, they were significant enough to note. The plan now is to look into these suspension concerns at a separate track day that will be fully dedicated to suspension testing.
Towards the end of the track day, we observed a minor issue with our Low Voltage battery and after replacing the battery, the car ran as normal. While not a critical fault, it’s something that will be logged and will be looked into by our Low Voltage team members back at the workshop.
Although we encountered a few challenges, the day was overall both productive and safe. The testing allowed us to uncover several important points for improvement, and we gathered a large amount of valuable data for both our HV and LV systems to work on. These insights will play a crucial role as we move forward in preparing and refining our 2025 vehicle.
