Spoiler (car)
A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across the body of a vehicle in motion, usually manifested as lift, turbulence, or drag. Spoilers on the front of a vehicle are often called air dams.
Spoilers are frequently fitted to race and high-performance sports cars, although they have also become common on passenger vehicles. Spoilers are added to cars primarily for styling and either have little aerodynamic benefit or worsen the aerodynamics.
The term "spoiler" is often mistakenly used interchangeably with "wing". An automotive wing is designed to generate downforce as air passes around it, not simply disrupt existing airflow patterns. Rather than decreasing drag, automotive wings actually increase drag.
Aerodynamics plays a critical role in a car's behavior at higher speeds. Vehicles must be stable and balanced first at lower speeds through their mechanical grip on the road via the chassis, suspension, and tires. Aerodynamic aids can then be used to provide the necessary balance and stability characteristics at higher speeds. Spoilers and wings on a vehicle have little effect at low speeds as improper designs may create undesirable responses and lower stability or efficiency for the car at high speeds.
Since "spoiler" is a term describing an application, the operation of a spoiler varies depending on the particular effect it is trying to spoil. Standard spoiler functions include disrupting airflow passing over and around a moving vehicle. A standard spoiler diffuses air by increasing turbulence flowing over the shape, "spoiling" the laminar flow and providing a cushion for the laminar boundary layer.[citation needed] However, other types of airflow may require the spoiler to operate differently and take on vastly different physical characteristics.
While a mass travels at increasing speeds, the environment's air affects its movement. Spoilers in racing are combined with other features on the body or chassis of race cars to change the handling characteristics affected by the environment's air. Race tracks demand specific aerodynamic configurations due to the varying speeds and track layouts. Configurations and devices may also be tailored to suit the talents of a particular driver, with the overall goal of reaching faster times.
A car's performance is susceptible to the aerodynamic forces acting upon it because both drag and downforce increase proportionally to the square of velocity. This relationship has implications for vehicle setup. At speeds below about 120 mph (193 km/h), aerodynamics plays a role, though the emphasis shifts.
The goal of many spoilers used in passenger vehicles is to reduce drag and increase fuel efficiency. Passenger vehicles can be equipped with front and rear spoilers. Front spoilers, found beneath the bumper, are mainly used to decrease the air underneath the vehicle to reduce the drag coefficient and lift.
