Discover Technology and Teamwork as One

A HANDS ON STUDENT PROJECT

Under the umbrella of MAKE Projects in the EPFL, the EPFL Racing Team is among the biggest scale projects made on campus. For the members of the team, Formula Student is an excellent way to put into practice everything learned in theoretical courses during the many semesters of their university careers. These students are either designing systems from scratch or improving systems tested on previous cars. From software to hardware, each part is made to perform best on track. These single seaters being composed of numerous complex interconnected systems, this project is highly interdisciplinary and brings students from many engineering specialties together. By the end of their experience as part of the EPFL Racing Team, every member gains key practical and theoretical skills through building the engineering marvels that these race cars are! 

ARTEMIS

May 25 we unveiled the newest addition to the EPFL RT family: Artemis. As the first hybrid-monocoque of the team, this car is a huge step toward new horizons. With torque vectoring and regenerative braking, Artemis promises to be more solid, safer and more efficient than our previous cars.

The team will be present at FS Switzerland in Zurich, FS EAST at Hungaroring, FS Germany in Hockenheim and FS Spain near Barcelona. Follow us to be updated on our adventures!

Mercury

The 2019 season’s battle-hardened team went to work on building the team’s second car: Mercury, which was completed in 2021. The new insider knowledge permitted us to improve the technology in the car, notably turning to composite fibre for the body and aero kit, as well as developing the electronics. Due to the COVID-19 pandemic, the 2020 FS racing season was cancelled, and the team had an extra year to perfect the design and manufacture. Although there were times quarantine prevented active work on the car, eventually the team again came together to build, in our new lab space on the EPFL Campus. Mercury went to FS Czech Republic, FS East and to FS Germany. Overall, the team celebrated a rule-compliant car which successfully completed the team’s first Endurance race on the Hungaroring in FS East! Since the competitions, Mercury has been used for testing: mainly checking the aero kit and verifying its maximum capacities. Now, it is being reutilized by the Driverless division to become the EPFL Racing Team’s first autonomous car.

Orion

The team first competed in 2019 with our car: Orion. At this point, the rookie team was formed of around fifty students. This first car was a major challenge, it had to be reliable : reducing the risk of electrical or mechanical failure. If this was achieved, the experiment of building a car for the first time would open the doors for future vehicles and competitions! The team completed a functioning and sturdy car with a complete aero kit, although the car was lacking in electronics, with in-house AMS and safety circuits that were not on point. We went to FS Spain in Barcelona and FS Germany in Hockenheim, although without much success. The most important thing was that the team had learned the true undertaking that making a Formula Student Car is. Additionally, we learned a vast understanding of the teamwork such projects require, as well as how to collaborate to tightly integrate all components of the car and the business.
