wat is the need of spoiler in cars??

Question

why are spoilers kept in cars , wat i sthe function of them?

Answer 1

they keep the car from flying off the ground
It acts like the wing of a plane except instead of generating lift in generates the opposite so the car stays on the ground. They are only functional when u are going 140+++.

Answer 2

A spoiler directs air down on the car and pushes the car down on its wheels to get better traction. On cars that are driven everyday on the highway, the spoiler is basically for looks because the car is heavy and the spoiler is small and therefore the push isn't very effective. But on race cars where the spoiler is large and the car is light, they make a huge difference. Also the faster the car goes, the more air goes across the spoiler and the harder the spoiler pushes down the car . the harder the push, the better the tires will grip the road. In the old days people thought burning the tires was cool, but it doesn't take a rocket scientist to know that if your tires are slipping your car is loosing forward motion and anything you can do to stop the slipping is an advantage.

When a car is traveling at high speed, the air rushing underneath it can create lift - something you do not want on a car. A spoiler creates downforce on the vehicle to cancel, or "spoil" this lift out. The increased downforce provides additional traction to the wheels in which it is placed over and can improve handling

Spoilers on passenger cars are typically placed at the rear of the vehicle. Although it is popular amongst some to add a large aftermarket spoiler to their car, it's functionality is questionable. Firstly, most of the popular "tuner" cars are front wheel drive, so while adding additional downforce to the back end may help to balance out the skewed front/rear weight ratio and reduce oversteer (not usually a problem with FWD anyways) in a FWD car it certainly does not add any traction to the drive wheels. Secondly, spoilers will usually add some additional drag to the car, excessively large spoilers may add so much drag that top speed and high speed handling are negatively affected.

In racing and performance cars, spoilers are designed and added by engineers who test the effects of the spoiler through calculations, wind tunnel tests and computer simulations to determine what performs best. Just going out and putting a huge spoiler on your car may look cool (or ridiculous depending on your taste) but it wont necessarily give any sort of performance or handling benefits.

To sum it up, a good percentage of spoilers you see on passenger cars are simply a styling element - ie: they're just for looks.

Answer 4

A functional spoiler adds downforce as speed increases, causing greater traction without with no increase in momentum, so cars can corner safely at higher speeds.

Toy spoilers on passenger cars just look good, decrease gas milage in some cases, and fool the driver into thinking he is cooler.

For real.

Answer 5

They don't do much at low speeds, except look cool. However, if it is a real spoiler, and is amde for it, at higher speeds, aroudn 60-80 mph, it begins to take effect. The effect is that it holds the car to the road better by creating a down force, like an upsidedown airplane wing. It creats lift downwards, or is at least supposed to. Hope this helps.

Answer 6

Spoilers were first put on race cars in the 1960's to keep the cars from becoming airborne. Today, spoilers are put on passenger cars for looks; they serve no practical function whatsoever, because passenger cars do not go fast enough to need them.

Answer 7

From what I hear, it's to stablize the vehicle at high speeds. However, for most cars these days with spoilers, the only function is trying to make the car look cool.

Answer 8

On cars that fast enough to lose traction going at high speeds the spoiler creates a downward force to keep the tires more securly on the road.

Answer 9

They keep pressure on the rear tires in cars that are rear wheel drive, and actually fast enough to have to worry about breaking loose at high speed. But on most ricers and passenger cars they are for looks.

Answer 10

THE PURPOSE OF A SPOILER IS TO CREATE DOWNFORCE, IT IS LIKE THE AIR IS PUSHING DOWN ON THE CAR, HIGH END CARS SUCH AS FERRARI HAVE FRONT AND UNDERNEATH SPOILERS TO FURTHER INCREASE DOWN FORCE, SOME SPOILERS ON THESE IMPORT CARS SUCH AS CIVICS SERVE NO PURPOSE BUT FOR LOOKS, AND SOME ACTUALLY CREATE LIFT, WHICH CAN MAKE HANDLING WORSE AT HIGH SPEEDS, SPOILERS ARE IMPORTANT AT HIGH SPEEDS ESPECIALLY FOR REAR WHEEL DRIVE CARS TO KEEP DOWNFORCE ON THEM FOR TRACTION AND CONTROL
