2024
Info
Founded in 2018, Sirius is EPFL Racing Team's 5th Formula Student Car. To develop the most competitive car possible, Sirius builds on Ariane's platform with full monocoque, AWD and driverless capabilities but aims to optimise the concept. Performance is improved through weight reduction, new suspension kinematics and dynamics based on whole car vehicle simulation. Reliability is improved through the creation of new shutdown measuring points, more robust cable management and increased testing.
Engineering Design Priorities:
Weight Reduction

2023
Info
We present Ariane, EPFL Racing Team's fourth ever vehicle! After a successful 2022 season, we have decided to introduce a number of technological improvements such as a move from a 2-wheel drive system to a 4-wheel drive in-wheel propulsion with traction control and torque vectoring, increasing battery voltage from 430 to 600V, going from a semi- to a full carbon monocoque, a new heave-roll suspension architecture, improved aerodynamics and the introduction of our first driverless systems.
Engineering Design Priorities:
4-wheel drive
Complete CFRP monocoque
Driverless

2022
Info
The EPFL Racing Team is back with our third car, Artemis, for the 2022 FS season! After the 2020 season was cancelled due to covid, last summer taught us to listen, to rethink and to remake! We will compete with our first hybrid monocoque chassis this year: Artemis, which is geared to optimise the designs of the team’s previous cars. All divisions working on Artemis took the feedback from 2021 in stride, and we will be back stronger than ever!

Info
Thanks to our new and motivated team, we had the opportunity to really focus on research and development this year, to make a big step forward and try to catch up with the teams that have been in the business years before us. We also greatly progressed on the manufacturing side; developing our first parts in carbon fiber. We were able to test, try out, experiment and learn all year long, and this resulted in our newest and best race car: Mercury.

Info
The Lausanne Racing Team is a rookie Formula student team. From EPFL Lausanne, It gathers 50 people around this electric race car project. For its first apparition on track, the team is presenting Orion, whose focuses on reliability in order to build a solid basis for the years to come. It is also a more environmental friendly EV thanks to the use of flax fiber for most of the composites. Come and hang out with our team in the pits to discover more on the project.
