Team Description

Mainfranken Racing at Technical University of Applied Science Würzburg-Schweinfurt is a non-profit association‚ that was founded in September 2006.
Born out of the idea of some motor sports enthusiastic students.

After participating at Formula Student Germany in 2007 we finished with 14th place overall and 2nd runner up in the newcomer competition in Hockenheim.
These results pushed our ambition to build an even better car over the past fourteen years.
With the knowledge of fourteen seasons in Formula Student we look forward to present our MF15 at the Formula Student Events in 2023.
After the switch to EV 2018/2019 we are now presenting our first EV car with integrated Driverless components.

The Team started with 20 active members into the new Season 2022/2023. Together we want to grow not even our experience & knowledge but our team.
Furthermore we want to provide a basis for future seasons at our university.

Mainfranken Racing e.V. was founded in 2006 by motorsport enthusiasts from the UAS Schweinfurt. The team consists of around 20 motivated students building the team's 17th race car. The drive concept includes a rear-wheel drive. Additionally, the focus is on applying the knowledge gained from last year's CRFP monocoque production and development. Furthermore, an important focus for this year's MF17 is to improve our driverless System.
