An undertray, also known as a belly pan or underbody shield, is an aerodynamic component used in automotive design to smooth the airflow underneath a vehicle. By covering the complex and irregular components of the lower chassis; such as the engine, suspension, and exhaust system, an undertray reduces drag.

Diffuser (automotive)

A diffuser on an automobile is a shaped section of the car’s rear which improves its aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. It works by providing a space for the underbody airflow to decelerate and expand so that it does not cause excessive flow separation and drag, by providing a degree of "wake infill" or more accurately, pressure recovery.

Ground effect (cars)

In car design, ground effect is a series of effects that have been exploited in automotive aerodynamics to create downforce, particularly in racing cars, through underbody tunnels and floor design. This has been the successor to the earlier dominant aerodynamic focus on streamlining.
