FSE.07

The seventh generation of the Formula Student monopost was designed with a focus on reliability and improved driving characteristics. The changes from the sixth generation were based on the results of tests conducted on the previous monopost. Using the data obtained from testing, the team was able to enhance the car’s performance on the track.

Improved engines, a new battery, and control elements, along with a redesigned composite full monocoque, secured double victories that year. The season brought the team closer to a perfect understanding of their concepts.
