In this paper, we deal with a monocoque body, carbon wheel and engine mapping for student formula vehicle. In the case of monocoque body, it was designed and manufactured based on torsional stiffness. By the torsional stiffness test, it is possible to make the monocoque body lighter than the steel tube frame structure and higher in torsional stiffness. Also in order to reduce the rotational inertia of the drive system, the existing aluminum wheels were replaced with the carbon wheels directly designed and made. We have developed a design with a higher lateral stiffness and a lighter weight than aluminum wheels and validated by lateral stiffness test using natural frequency. We are proceeding with mapping using 250cc engine and aftermarket ECU, and we optimized mapping using optimization program. As a result, we were able to shorten the time and create a more complete map.
