Rennteam X3

History of the Team

The Legacy of Rennteam Uni Stuttgart:

Founded in 2005, Rennteam Uni Stuttgart has spent the last two decades at the forefront of automotive engineering excellence. Located in the heart of Germany’s automotive hub, our team consists of dedicated students pushing the limits of EV technology. Over the past 20 years, our continuous pursuit of innovation has earned us a Top 6 World Ranking in the EV category and the title of Number 1 team in Germany.

The Combustion

The history of the Formula Student team at the University of Stuttgart began in 2005 with the founding of Rennteam by Michael Kissling, Konrad Paule, and Sebastian Seewaldt. The second season marked a significant milestone for the team, when they clinched their first overall victory in the combustion class at the Hockenheimring with the F0711-2. This success not only affirmed the team’s determination and technical expertise but also laid the foundation for an impressive series of achievements in the years to come.

The Electric

In 2009, the decision was made to establish a second team, GreenTeam. Since then, Rennteam focused on designing a combustion engine vehicle while GreenTeam focused on manufacturing an all-electric vehicle.

Both teams were able to leverage the experiences of previous seasons, and GreenTeam secured an overall victory for Stuttgart in its very first season.

The Record Hunters

In 2012 (E0711-2), 2015 (E0711-5), and 2022 (E0711-11 EVO), they even managed with the help of their “Förderverein” to break the world record for acceleration from 0-100 km/h with a time of 1.461 seconds. The “Förderverein” of the GreenTeam looks after its old vehicles and supports the team in developing new vehicles. More about the “Förderverein” can be found here.

The Reunification

With the decision to abolish the combustion class starting from the 2023/2024 season at the Formula Student Germany, it was decided to reunite the two previously seperate teams. Therefore, from this season onward, there will only be one Formula Student Team at the University of Stuttgart, Rennteam Uni Stuttgart.

The team’s focus will now be entirely on the design and manufacturing of an electrical race car, which will also compete in the Driverless category. By coming together, the teams can draw upon their extensive experience in designing and building over 30 race cars with electric motors and combustion engines, and can combine the strengths of both teams.

Our Team

The team consists of students from various fields of study and places great emphasis on personal responsibility, professionalism, discipline, and quality. Work is carried out in different “subteams,” each led by a subteam leader, and the entire racing team is overseen by the chairpersons. Rennteam Uni Stuttgart e.V. is a registered association.

Location

The development and manufacturing of the race cars primarily take place in our own building on the campus in Vaihingen. This facility provides space for an office, a kitchen, and several fully equipped workshop rooms.

Our 2025 car: the X2

New Aerodynamics, improved reliability, 1st Place winner

The 2024/25 season race car, Rennteam X0711-2, is one of our most successful electric cars, boasting nine individual victories and two overall podium finishes. A newly developed aerodynamic concept has significantly optimized driving stability and downforce.

X0711-2 is powered by four extremely lightweight, in-house developed electric motors with a peak output of up to 50 kW and a maximum speed of 21,000 rpm. Our car even drives autonomously. Thanks to optimized LiDAR technology, we achieved the first driverless victory in our team’s history this year.

Our 2026 car: the X3

Engineering the X3 Our latest project, the Rennteam X3, represents the pinnacle of our 20-year history, faster and lighter than ever, we plan to win FSG(Formula Student Germany), the most prestigioius competition in this field.

Our request:

To maintain our world-class standing, we are focused on radical weight reduction and extreme packaging efficiency. In a high-vibration, space-constrained racing environment, traditional wiring and standard PCBs are no longer enough.

I am a member of the Electrics Sub Team and personally put a lot of effort into the electrical system. However, we have been struggling to find a manufacturer who can build the flex pcbs that we need to manufacture our HV Accumulator.

Why We Need PCBWay:

To bring the X3 to life, we are implementing advanced Flex PCB designs for our HV Accumulator. This technology is vital for our data acquisition and battery management systems, allowing us to save weight and improve reliability on the track.

We are looking for a partner like PCBWay to help us bridge the gap between our high-performance designs and reality. By supporting the X3, PCBWay isn't just manufacturing a board; you are helping the top team in Germany defend its title and celebrate 20 years of racing excellence.
