Info
Mkx. VI marks a major milestone in our team’s history: debuting a car with a fully integrated aerodynamic package. Our design focuses on structural weight reduction, enhanced maintainability, and a functional lightweight aero concept. Since 2018, we have been competing internationally with vehicles entirely designed and build in-house. This achievement is made possible by our dedicated students from a wide range of disciplines - turning the impossible into reality.
Engineering Design Priorities:

Info
The Mkx.IV, the newest addition to the Formula Student Team Chemnitz family! With the fourth vehicle in our history we want to show how a relatively simple drive concept can perform optimally on the tracks of the Formula Student. This year´s extensive focus has been on scoring dynamic points and the implementation of our first autonomous system. With Mkx.IV we, about 60 students of the TU Chemnitz, show how optimal installation space can be used. Check out our package.

Info
The T.U.C. Racing e.V. was founded in 2015 at the TU Chemnitz. With our more than 50 members, we have developed the third vehicle in the team history in the last two years. In the vehicle concept and manufacturing of Mkx.III our focus was especially on reliability and a high manufacturing quality.Thanks to our mascot on the nose of the vehicle, we are bringing a little bit of Karl-Marx-Stadt to all of Europe. We are looking forward to finally seeing you again at FSG 2022.

Info
T.U.C. Racing from the TU Chemnitz was founded in 2015. Since then we are electrified and unstoppable! After our premiere last year, over 50 team members spent hard and endless hours in the workshop to bring our second car - Mkx.II - to the race tracks of Europe. The experiences of 2018 gave us a lot of motivation and now we are heading to the finish line with the throttle full open! Feel free to meet our awesome and incredibly devoted engineers in the pit! #madeinsaxony
