The URE15 was the second car URE built using the modular driverless and electric concept. It featured, among other improvements, a brand-new multilink suspension and major improvements to the driverless software and hardware. Due to the COVID-19 pandemic, all formula student events for the 2019-2020 season were canceled, and for this reason, the URE15 was developed over two years.
During the second year of development, the focus was put on finishing the car as soon as possible. This, in combination with numerous hours of static and on-track testing, ensured that the car was at its maximum performance during the competition. Ultimately, the URE15 turned out to be the best performing car ever developed by URE with 2nd place at FSN Electric and 1st place at FSS Driverless.
