What are Car Spoilers used for on the back of come cars?

Question

I brought the car I have now, and it has a Spoiler on it. Has just wandering what their purpose is!

Answer 1

In fast cars, they provide down force for high speeds so the air pushes the car to the ground so it does not fly away at high speeds.

Fast cars like Porsche's and Ferrari's.

In normal cars, it is just for a sporty look.

Answer 2

Apart from giving a sporty look, the real purpose is when you drive at high speed, the spoiler keeps the air down so that the car will not jump and the drive will be smooth.

Answer 3

unless its a race car there is no purpose its just for looks. race cars have them to give the car more down force on the rear tires thus giving them more traction at higher speeds.
