EDGE10
// The first heart from in-house development
With the EDGE10 we can look back on a decade of student racing. Further developments in aerodynamics, such as the active front wing connection or the newly developed rear wing, have achieved the best downforce values since the beginning.
However, the main focus this season has been on electrical engineering. The entire low voltage system is now more reliable and easier to maintain. The battery has become safer and now delivers 530V. This is made possible by our self-developed inverter, which was used for the first time this year.
