In 2011, our team, the BME FRT is building its 4th petrol car, the FRC04. Learning from our experience we decided not to change the basic concept of the latest car (Tubular spaceframe, 4 cyl engine) but to develop and build it more precisely and what is also important, to finish it early in order to test as much as possible. Compared to the FRC03, the car is more than 20% lighter, due to paying more attention to choosing the right materials and CAD optimising. By using Multi–Body Simulation programmes, we have designed a completely new suspension and by learning advanced FEM techniques we have managed to design a frame 4 times stiffer. The team also expects a lot from our new ABS brake system which can become a great advantage to catch up with the top teams.
This season, we have also started our knowledge transfer process to the new team members and have recruited a Junior Team who are preparing for 2012. We have also begun to advertise technical education in Hungary. By displaying our car we have shown the possibilities in higher technical education for many highschool students, making them more enthusiastic for technology.
