Spoiler (automotive)

A spoiler is a device that goes on the back of a car or truck. It helps the car drive better and faster. A spoiler has a flat bottom and usually a curved top. It is designed to disrupt the air that is flowing over the back of the car, making the car more efficient. By disrupting the air, the spoiler is able to reduce drag. This means the car will require less fuel and be more aerodynamic, which helps it move faster.
