Team Profile:-
EC-01 is the first Formula Student car of ESTACA, our French Engineering school specialized in transportation. ESTACA Formula Team couldn’t have realized this newcoming car without the great help of Aixam Mega, Facom, and 3 technical high school : AFORP, GARAC and Lycée Le Corbusier; with which we shared the manufacture of EC-01.
The project began in September 2011 with the aim to design and manufacture the most reliable car with an expected weight of 200kg.
Our simulations allow to show how much handling our car needs to obtain good results at autocross and also how much power we need. So we have selected a 450 cc single cylinder which offers weight reduction and ease of use. This provides a gain of 30 kg, a consumption reduction (30%) and simplicity compared to 600cc 4 cylinders. Our car is small, with 10 inch rims, which brings lightness, while reducing rotating masses. The double wishbone suspension is fully adjustable with 4 channels adjustable shock absorbers, to provide maximum performance through the settings. The chassis is a tubular space frame, chosen for its simplicity and low cost compared to monocoque. Overall, we did not attempted lightness using costly complex technology but simple solutions.
