NO. Spoiler and wing are two different aerodynamic features of a vehicle. Spoilers are generally closer to the body of a vehicle and it helps diffuse air. Wings, on the other hand, are mounted much higher up and create downforce that provides more aerodynamic effects. Wings almost work like an upside down air plane wing.
In the simplest form fast moving air creates pull if the other side of an object is exposed to slower moving air. If you want to test the theory, you can take 2 sheets of paper then hold them between your thumbs and little fingers, in such a way that there is a gap between the sheets of about an inch. Blow between the 2 sheets and you will notice that they pull together, which is not what you expect to happen. The fast moving air generates low pressure region in between the paper will cause them to pull together.
So as to create lift or down force, you will need air that will move faster on one side of the aerofoil than on the other creating a pull towards the fast moving air stream. We can use a simple 2 deck deflection in creating the down force required.
Deflection will have a bearing on the amount of downforce created and the larger the angle, the more downforce there will be. However, you will pay the price with an increased drag. Most wings contain a two-angled surface having a two stage deflection that force air over the wing, taking a shorter route than the air going under the spoiler.
Looking at the typical shape of a car, you will notice that air will travel further and faster over the top of the car, than it dows underneath. This will create lift then. If you open the sunroof at speed, problem with aerodynamics will be induced.
Imagine you car as a see-saw. When you press down on the rear, the front will be lifted slightly. As you fit the spoiler to the rear, the front of the car will be lifted even higher at high speeds. This will be undesirable in a front wheel drive car. And in a rear wheel drive vehicle, you will need the front wheels to steer even if traction is enhanced a degree of lift at the front is adverse.
To counter the front lift, splitters can be used. Also, front and rear skirts can be fitted to create downforce at the front of the car so that the amount of air rushing under the car is controlled. As you start redirecting the air rushing over the car, an amount of drag will be generated to rob your speed and fuel economy. There will therefore be a line between an efficient spoiler and wing design and inefficient ones.
The best wings are usually adjustable so that the driver can set his preferences to track conditions. You can find such advanced features on most sports cars today such as the Ferrari models.
Indeed, spoilers and wings are great for enhancing the aerodynamics of your car. If you want to enjoy a really smooth and seamless downforce and air redirection, then you need to have your spoilers and wings properly installed on your car. This may seem simple but if you try to figure it out, it is such a complicated task. Better yet, if you are not confident of your own skills, look for a qualified technician who can have your spoiler and wings installed successfully.
Even so, make sure that you will choose the right spoiler and wing for your ride. A lot of non-standard spoilers and wings are available in the market, so beware. If you happen to get such non-standard parts, your vehicle’s aerodynamics will be affected significantly. Remember that these aerodynamic parts must not reduce fuel economy. Be wise in selecting your new spoilers and wings then.
