Team Description

At the end of the 19th century the automobile engineers August Horch and Friedrich Opel studied at the Technikum Mittweida.
More than 100 years later, the Technikum Mittweida Motorsport was founded to revive the history of motorsport at Mittweida.
Between 2006 and 2016 the students of the TMM developed and built six combustion vehicles under the FSAE regulations.

In 2017 Technikum Mittweida Motorsport Electric was created as a new brand to take the step into the future and participate in the Formula Student Electric.

Car #32 Golden Serpent

Info

TMM Technikum Mittweida Motorsport proudly celebrates its 20th anniversary with the presentation of the 10th Formula Student race car, the Golden Serpent. Named to honor two decades of passion, innovation, and teamwork, the Golden Serpent combines the colors of every TMM car built since 2006 while remaining true to the iconic snake-inspired design. More than a race car, it represents the dedication of generations of team members and the legacy they have built together.

In memory of the well-known automotive pioneer August Horch, who himself studied at the University of Applied Sciences Mittweida from 1888-1891, students of mechanical engineering came together in 2006. As “Technikum Mittweida Motorsport” they began to develop their first racing car for Formula Student. Since 2018 the team has been developing electric vehicles and will compete this season with their Black Mamba.
