Additional components on cars such as spoilers are increasingly sought after as a showcase of style. Components that look like a rear wing certainly make the car look sportier. But did you know that the function of a car spoiler is not just for style or modification to look good? Curious, right? Let's take a look below!

What is the Function of a Spoiler on a Car? Check it Out!

So, what is a car spoiler? A car spoiler is a car component that affects aerodynamics and has the function of increasing downforce or downward pressure on the car. The three main functions of a car spoiler are as follows:

1. Increases Downforce

What is the function of a spoiler on a car? Broadly speaking, the function of this spoiler or wing element is to regulate the aerodynamics of the vehicle. If you are not familiar with automotive, it can be said that this wing will manage the airflow that blows past the car. Generally, the wind hitting the car while driving at high speed will create lift.

That is why many vehicles experience difficulties in acceleration or even de-acceleration. This is where the spoiler comes into play. The wind that lifts the rear part of the car will be forced down by the presence of the spoiler. This pressure is also known as downforce which is useful for reducing lift.

In general, the function of this element will be felt in sedan or hatchback type cars. Vehicles like cars have aerodynamics that are greatly influenced by speed. At high speeds, the function of the spoiler is to maintain the aerodynamics of the vehicle so that the wheels and the vehicle stay on the road.

2. Improves Car Handling

The problem of losing control when the vehicle is moving fast often occurs not only because of the driver but also from the car itself. One of the root causes is aerodynamics. When the car's downforce is low, the lift force will make the car float, hard to control, and less stable.

If this is left unchecked, the car could flip or even slip. This is certainly very dangerous, especially if you are driving on the highway at high speeds. This is where the rear spoiler of the car will show its important role. The spoiler will enhance the aerodynamic effect and downforce of the vehicle.

The addition of this element is actually quite common for hatchback or sedan type cars. This is done to make handling more stable and safe. Even NASCAR or F1 racing cars use the function of spoilers to keep them stable and glued to the road.

3. Supports a Sporty Appearance

This additional element has a wide variety of appearances and designs. Not only that, but its placement also varies from each type of car model. So, it's no wonder that many automotive enthusiasts modify their vehicles. This is also supported by the ease of purchasing such elements.

Many car manufacturers offer spoilers, but you can also order and install them yourself. Vehicle modification is no longer a strange thing among automotive lovers. However, the placement and design can actually affect the vehicle's performance. That is why you should not just install it anywhere.

In general, the aerodynamics of a vehicle must be balanced. If you only focus on installing a spoiler at the back, then downforce will only be concentrated at the rear of the car. You need to balance the function of the spoiler by installing it on the sides and also the front bumper.

At least that is what you must know about the wing component on cars. Although often used only to support appearance, this additional element also greatly affects the aerodynamics of the vehicle. That is why the spoiler will provide effects on vehicle handling and downforce.
