A spoiler is essentially a flat-ish panel installed at the back of a car to provide downforce.
Spoilers are one of the most common car accessories not only for sports cars but also for sedans, roadsters, and other commonly used vehicles.
Different cars have different types of spoilers with some optimised for function and others fitted to enhance the design of cars.
The main function of spoilers, however, is to increase their grip on the road. Without spoilers, the only way to increase the grip would be to increase the weight load of the car or to change the compound the tire is made out of.
Here is how spoilers work to ensure drivers have a seamless experience on the roads.
Ensure Vehicles have better control at high speed.
A spoiler reduces turbulence which improves the stability of the vehicle at higher speeds as well as enables better handling during difficult situations on the road by allowing for easier directional changes.
This ensures that there is no air resistance pushing against the car causing slower movement or causing it to turn in the wrong direction.
Balances air flow underneath the vehicle
When cars are moving at high speeds over 100 kilometers per hour or more, the air pressure underneath the vehicle is much less than that above it.
Spoilers cause pressure to increase further forward causing the airflow underneath the vehicle to balance.
Spoilers maximise downforce
High-speed vehicles experience downforce which occurs when air resistance is angled downwards towards the road surface creating two opposing forces pushing against each other.
Spoilers contribute to maximising this effect by redirecting airflow so that appropriate pressure differences are created helping keep the car stable no matter how fast it goes.
They are installed for styling
Regardless of the reason for the spoiler, it changes the appearance of a car and can influence the buyers who choose vehicles that are more appealing.
