A rear valance is a panel located on the underside of the rear bumper of a car. It is used to help improve the aerodynamic performance of a vehicle by reducing drag.

Rear Valance: Definition

A rear valance is a panel found on the underside of the rear bumper of a vehicle. It is designed to enhance the aerodynamic performance of the vehicle by redirecting airflow around and away from it. The valance also provides protection for any parts located underneath the rear bumper.

The rear valance typically has three main components: an upper edge, a lower edge, and a center section. The upper edge is designed to channel air over the top of the bumper, while the lower edge helps direct air away from the bottom. The center section helps reduce drag by breaking up the airflow and allowing it to pass smoothly around the car’s body.

Rear valances come in various shapes and sizes depending on make and model. They are usually made out of plastic or fiberglass, although some vehicles may have metal or composite materials used instead. Some vehicles may also have additional parts such as grilles or diffusers attached to their rear valances.

The installation of a rear valance can help improve fuel economy and performance by reducing drag and improving aerodynamics. It can also add an aesthetic touch to a vehicle, giving it an aggressive or sporty look.

What Does a Rear Valance Do?

A rear valance is an aerodynamic panel that is located at the bottom of the rear bumper on many cars. It is designed to improve the car’s aerodynamic performance by creating a smoother flow of air around the vehicle. The valance also helps to reduce drag, which in turn increases fuel efficiency. Additionally, it helps to protect the rear bumper and bodywork from road debris and other flying objects.

The shape of a rear valance can vary depending on the make and model of car, but they generally consist of a flat, curved piece of plastic or metal that attaches to the underside of the rear bumper. Some cars have a more pronounced ‘air dam’ design which is meant to channel air around the car more efficiently and provide additional downforce at higher speeds.

The main purpose of a rear valance is to reduce drag and improve aerodynamics. This can help make your car more fuel efficient and provide improved handling performance, especially at higher speeds. Additionally, it can help protect your car from road debris, stones, dirt and other flying objects which could damage your paintwork or bodywork if left unchecked.

Furthermore, some cars feature custom-made rear valances that are designed with specific styling in mind. These can be made from different materials such as carbon fiber or fiberglass and often feature unique designs that give your car an eye-catching look as well as improved aerodynamics.
