Team Description
In spring 2004 a small group of engineering students at University of Bayreuth's then youngest faculty founded Elefant Racing. The name is derived from the Faculty of Applied Sciences' abreviation FAN which shares its letter string with the clever and powerful animal. The team took part in European competitions since 2006. In September 2010 we decided to run the season with a full electric vehicle within the rules of the FSE.

Established 2004, Elefant Racing e.V. ventured to electric racing in 2011. We marked 2019 with two substantial achievements - pioneering autonomous driving capabilities and rolling out the first generation of our self-developed electric motors. By 2024, we install our fourth-generation electric motors, which were improved for weight reduction. The main aim of our club is to offer engineers a practical outlet for the theoretical aspects of their studies, thereby enhancing their learning journey.

Founded in 2004, our team Elefant Racing from the University of Bayreuth is one of the oldest Formula Student Teams in Germany. In 2011 we changed from CV to EV; since 2019 we are using 4WD and since 2020 our team also competes in driverless competitions. We are proud to present our brand new car - theFR22 Thor. The FR22 features a fully integrated DV system, a highly improved torque vectoring and traction control systems. We are looking forward to exciting days at FSG 2022.

This year might just seem like one more of a decade of participating at the FSG. But right after our change to electric, it is one of the most exciting ones. This year we’re going big – we’re happy to present the FR19 Loki, our first four-wheel-driven racecar. Therefore, many concepts had to be improved and we found new ways to take it to a whole new level. With the great support of our sponsors and the University of Bayreuth, we’re glad to exceed all hopes and coming back stronger…

In spring 2004 a small group of students, at the University of Bayreuth, founded “Elefant Racing e.V.”. The name is derived from the Faculty of Applied Sciences, abbreviation FAN, which shares its letter string with the clever and powerful animal. Starting into season 2010/11 we decided to break with our tradition of building combustion cars and developed our first electrically powered vehicle. With the “FR13 Cyrano”, our third high performance electric race car, the main attention was directed at weight reduction of the electrical power train. Furthermore, our car features an innovative driver interface based on a smart phone. It supplies the driver with real-time information about the car via display and computer-generated audio feedback. Additionally we designed a cable-based steering system, to achieve a more direct feedback, by eliminating the steeringplay.

Starting into season 2010/11 we decided to brake with our tradition of building monocoque combustion cars.

Based on the special characteristics of electric engines – especially a thrilling high torque through the whole rpm range - the FR12 offers an absolute new racing experience compared to conventional combustion engines. Up to 30 minutes enthralling racing experience are provided by 950 LiFePO4 accumulator cells with a capacity of 7.6 kWh.
