EPSA is a 40-student strong French FS team of the Ecole Centrale de Lyon. We have participated in the FS competition since 2014 in the CV category and are currently in our electrical transition. Our goal this year is to present our last CV prototype, Invictus. It was designed to be reliable, powerful and it gathers all the progress we made the previous years. Our project is special because we work with worker schools to produce the car and every member is never in the team more than 2 years!
Engineering Design Priorities:
Reliable
Ergonomic
Adjustable
Powerful
Long-lasting
Innovative
