Team Profile

EPSA is a team of highly motivated students from Ecole Centrale de Lyon, an engineering school in France. EPSA began designing its first prototype for the Formula Student competition in 2013 as a two-year project. A team of 11 students worked on the car, Dynamix, with which we are participating in FSUK at Silverstone for our first time.

The car was designed during the first year of the project, and was built and tested during the second year. The team’s aim is to build a new car each year, which means that while one car is being built a new one is being designed for the following year.

For our first car, our goal was to build a car that is strong, safe and sturdy, capable of finishing all the Formula Student dynamic events. While care was taken to limit the weight of the car, the priority was to ensure a solid mechanical structure and limit risks of mechanical failures, which is why most of the parts of the car are made from steel or strong aluminium.

We would like to thank all our sponsors and partners for their enormous help and support throughout this project.

 

Additional Information

  • The clutch disks on the car Dynamix have been changed twice… because the acceleration drivers love to practice their event !
  • Dynamix is EPSA’s first ever Formula Student prototype.
  • The interior of Dynamix’s cockpit is quite spacious for a Formula Student car, even for tall or large people.
  • The ending “ix” of Dynamix is inspired by the French comic book series “Asterix”, to mark the fact that the team is proud to be French !
  • Most of the team’s drivers have at some point broken a part of the car while driving during testing.
