<P> A spoiler is an automotive aerodynamic device whose intended design function is to ' spoil ' unfavorable air movement across a body of a vehicle in motion , usually described as turbulence or drag . Spoilers on the front of a vehicle are often called air dams . Spoilers are often fitted to race and high - performance sports cars , although they have become common on passenger vehicles as well . Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse . </P>
