Electric
When Formula Student Electric was launched in 2010, we entered the race with our first electric bolide in the same year.
Since 2014, we have been exclusively building racing vehicles with electric drives.

eace06
As the second all-wheel-drive vehicle, the eace06 was a further development on the concept of the eace05. However, no stone was left unturned in its development, so it features new chassis geometry, a new cooling system and a new aerodynamic concept.
Technical innovations
- Kinematics
Thanks to a completely revised axle geometry, the eace06 glides much more elegantly over the asphalt than its predecessors - Cooling system
The eace06's revolutionary cooling concept is, to our knowledge, unique in Formula Student. The water cooling of the battery and the power electronics is significantly more efficient than the air cooling implemented in the eace05. - Aerodynamics
An underbody concept and further developed front and rear wing geometries have given the eace06 downforce values that are quite impressive.
