Presently, CFD (Computational Fluid Dynamics) has taken a major role in the development of a new race car. Toyota has indeed understood this for some time since the Japanese manufacturer was already utilizing this tool during the era of the famous GT-One at the end of the 1990s.
CFD is used to study air flow on the car body: the more resistance the air encounters, the slower the car goes and the greater amount of energy must be produced to counter the the resistance and allow the car to move forward.
