SUVs are one of the most popular types of vehicles on the road today. They are known for their spacious interiors, rugged capabilities, and stylish designs. One feature that many SUVs have in common is a rear spoiler. But why do SUVs have spoilers? What is the purpose of this feature?
Spoilers are commonly associated with sports cars and racing vehicles, but they are also found on many SUVs. Contrary to popular belief, spoilers on SUVs are not primarily designed to make the vehicle go faster. Instead, they serve a more practical purpose. Spoilers are designed to enhance the vehicle’s aerodynamic profile, resulting in less drag and better fuel efficiency. Without this feature, the SUV’s shape would cause more wind resistance and cause the vehicle to lose out on gas mileage. In this article, we will explore the reasons why SUVs have spoilers and how they work to improve the vehicle’s performance.

The Function of Spoilers in Cars
Spoilers are a common feature in many vehicles, including SUVs. They are designed to change the airflow around the car, which helps to reduce drag and improve fuel efficiency. The primary function of spoilers is to create downforce, which helps to keep the car stable at high speeds and during cornering.
When a car is moving at high speeds, the air flows over the surface of the car in a specific way. This creates an area of low pressure behind the car, which can cause turbulence and drag. Spoilers are designed to disrupt this airflow, which helps to reduce the low-pressure area and decrease drag. This, in turn, improves the car’s fuel efficiency.
Spoilers also play an important role in keeping the car stable at high speeds. When a car is moving quickly, it can become unstable and difficult to control. Spoilers create downforce, which helps to keep the car glued to the road and prevent it from lifting off the ground. This is particularly important in racing and high-performance cars, where stability and control are essential.
There are different types of spoilers, including front spoilers, rear spoilers, and wing spoilers. Each type is designed to create downforce in a specific way and can be used to improve the performance of the car. Front spoilers, for example, are designed to reduce lift and improve the car’s balance, while wing spoilers are designed to create a large amount of downforce at high speeds.
Why Do SUVs Have Spoilers?
SUVs have spoilers for a few reasons. One of the main reasons is to enhance the vehicle’s aerodynamic profile, which results in less drag and better fuel mileage. Without a spoiler, the SUV’s shape would cause more wind resistance and decrease gas efficiency.
Spoilers also allow air to flow over the car with the least amount of drag. This means that the air doesn’t get caught up in the rear of the vehicle, causing less drag. When there is less drag, there is less force needed to keep the vehicle moving forward. This means the engine has to work less, which can result in better fuel efficiency.
Another reason for SUVs to have spoilers is to improve stability. Spoilers can help to provide more downforce, which can help to keep the vehicle stable at higher speeds. This is especially important for SUVs, which have a higher center of gravity than other vehicles.
It’s important to note that spoilers don’t actually make the vehicle go faster. Instead, they decrease the drag on the car, which means the engine has less resistance to overcome. The decreased resistance means the engine has less work to do in moving the car at faster speeds.
Benefits of Spoilers in SUVs
Spoilers are an important feature in SUVs, and they offer several benefits to the vehicle and its driver. Here are some of the benefits of spoilers in SUVs:
- Improved Aerodynamics: Spoilers are designed to change the airflow around the SUV, allowing it to flow more freely and reduce drag on the vehicle. This improved aerodynamics can result in better fuel efficiency, as it makes it easier for the car to move forward.
- Increased Stability: Spoilers can also improve the stability of SUVs at high speeds. By reducing the amount of wind resistance on the vehicle, spoilers can help keep the SUV grounded and prevent it from swaying or tipping over.
- Enhanced Traction: Spoilers can also improve the traction of SUVs, especially during cornering. By creating downforce on the rear wheels, spoilers can help increase the grip of the tires on the road, improving handling and reducing the risk of skidding or sliding.
- Improved Braking: Spoilers can also improve the braking performance of SUVs. By creating downforce on the rear wheels, spoilers can help increase the pressure on the brakes, resulting in shorter stopping distances and better overall braking performance.
Types of Spoilers for SUVs
SUVs come in different shapes and sizes, and so do their spoilers. Here are some common types of spoilers for SUVs:
- Lip Spoiler: This type of spoiler is a small strip that sits on the edge of the trunk or roof. It is designed to reduce drag by minimizing the turbulence created by the airflow over the vehicle.
- Pedestal Spoiler: This type of spoiler is larger than a lip spoiler and sits on a pedestal that is attached to the trunk or roof. It is designed to create downforce, which helps to improve the vehicle’s handling and stability at high speeds.
- Roof Spoiler: This type of spoiler is mounted on the roof of the vehicle and extends out from the back. It is designed to reduce drag by directing the airflow over the vehicle in a more streamlined manner.
- Wing Spoiler: This type of spoiler is similar to a pedestal spoiler, but it has a more pronounced shape that resembles a wing. It is designed to create more downforce than a pedestal spoiler, which makes it popular among SUV owners who want to improve their vehicle’s handling and performance.
Spoilers can be made from different materials, including plastic, fiberglass, and carbon fiber. Some SUV owners choose to add aftermarket spoilers to their vehicles for aesthetic reasons, while others install spoilers to improve their vehicle’s performance and fuel efficiency.
So, SUVs have spoilers to enhance their aerodynamic profile and reduce drag, resulting in better fuel efficiency. Spoilers decrease the resistance on the car, allowing the engine to work less in moving the vehicle at faster speeds. The decreased drag also means that the engine has to work less, giving you better gas mileage.
Spoilers also allow the air to not get caught up in the rear of the vehicle, causing less drag. This means that there is less force needed to keep the vehicle moving forward, resulting in better fuel efficiency. SUVs have a unique shape that causes more wind resistance, and the spoiler helps to counteract this effect.
While spoilers are primarily functional, they can also make the car look cool. However, it is important to note that spoilers are not a magic solution to make your SUV go faster. They are designed to improve the vehicle’s efficiency and performance, not to increase speed.
Overall, SUVs have spoilers to improve their performance and fuel efficiency. By reducing drag and allowing the engine to work less, SUVs with spoilers can achieve better gas mileage and have a smoother ride.
Do spoilers on SUVs make them go faster?
While spoilers can improve a vehicle’s aerodynamics, they do not actually make it go faster. What they do is decrease the drag on your car, which means the engine has less resistance to overcome. The decreased resistance means the engine has less work to do in moving the car at faster speeds. This can result in better fuel efficiency and a smoother ride.
Are spoilers on SUVs just for looks?
No, they are not just for looks. Spoilers on SUVs serve a functional purpose by improving the vehicle’s aerodynamics. Without a spoiler, the SUV shape would cause more wind resistance and cause you to lose out on gas efficiency. The spoiler allows the air to flow more smoothly over the back of the vehicle, reducing drag and improving fuel efficiency.
Can spoilers improve the handling of an SUV?
Yes, spoilers can improve the handling of an SUV by providing additional downforce. This downforce helps to keep the SUV more stable at higher speeds and during turns. However, it’s important to note that spoilers are not a replacement for proper driving techniques and should not be relied upon solely to improve handling.
Do all SUVs come with spoilers?
No, not all SUVs come with spoilers. Spoilers are often added as an optional feature or as part of a higher trim level. Some SUVs may also have a rear wing instead of a spoiler, which serves a similar purpose.
Can spoilers be added to an SUV after purchase?
Yes, spoilers can be added to an SUV after purchase. There are aftermarket spoilers available that can be installed by a professional or even by the owner themselves. However, it’s important to ensure that the spoiler is compatible with the specific make and model of the SUV, and that it is installed correctly to avoid any potential issues.
