what is the purpose of a car spoiler?

Whether you are a racing enthusiast or an automobile enthusiast, you have likely seen a car with a spoiler. But what is the purpose of a car spoiler?

A spoiler, also known as a wing or an air dam, is an aerodynamic device typically attached to the rear end of a car. It is designed to reduce drag and increase downforce on the car—both of which can improve the car's overall performance and handling.

Typically speaking, spoilers are either made from metal or plastic and come in several different styles. Generally speaking, they are divided into two categories: fixed and adjustable. Fixed spoilers come in one design while adjustable spoilers allow users to tune them based on their preference and performance needs.

The purpose of a spoiler is to reduce drag that occurs when air goes over the top of the vehicle and increase downforce that pushes the car closer to the ground for stability at higher speeds. Reducing drag helps lower fuel consumption as well as improve fuel economy, while increasing downforce increases traction which reduces understeer (when a car turns more than desired) and improves overall handling performance. Depending on the size and shape of your spoiler, you may be able to increase overall acceleration speed by adding more force to it when driving through sharp turns or going uphill.

Spoilers can be found on all sorts of cars from everyday commuters to supercars and race cars alike. They provide aerodynamic benefits that can help with improved performance and handling either on or off-road by providing stability at high speeds while reducing drag in certain areas of the vehicle's design. For race cars, this can directly translate into faster lap times due to improved airflow around the bodywork reducing turbulence that could slow it down in corners or during straightaways on longer tracks.
