The team consists of 25 members which are organised in groups: chassis, ergonomics, suspension, drive & transmission, brakes, impact zone, pedal box, fuel tank, gear shift, electronics, engine intake and exhaust, bodyshell, technical documentation, supply, production, cost report, administration, marketing. The team base is to design from the heart, considering engineering logic and scientific arguments. Our goal is a prototype racing vehicle fully defined with FS rules, but significantly unique, beautiful and with each component fully defined. We are proud to present our dreams and ideas through components made from various materials and various production processes. Our education combined with great effort resulted in an interesting product that is an elegant compromise between mass, safety and cost.
