The rear underbody component manages airflow as it exits the vehicle’s undercarriage. It is designed to accelerate the velocity of air moving underneath the car and encourage its expansion as it exits. This controlled expansion reduces pressure beneath the vehicle, contributing to overall aerodynamic efficiency.
Implementing this design offers several advantages, primarily increased downforce, which enhances stability and grip, particularly at higher speeds. This contrasts with earlier vehicle designs, which often neglected underbody airflow management, resulting in turbulent air and lift. The development and refinement of this element have become integral to optimizing vehicle performance in both motorsports and high-performance road cars.
