Can the SUV rear wing play a role in reducing wind resistance 10

Yes. The appearance of a car rear wing can reduce air resistance.

The drag of the car is cut, which reduces the wind resistance to a certain extent, and thus reduces the fuel consumption of the car.

Spoiler. The main function is to reduce the lift force at the rear of the body, if the lift force at the rear of the body is greater than the front of the car. This can easily lead to oversteer, reduced grip and poor overall stability at high speeds.

The addition of a rear wing results in greater traction on the ground and improves aerodynamics.

performance, so that the air has a more stable effect on the car.

The installation of the tail wing on the SUV to reduce the wind resistance can slightly start the effect, however, the main role of the installation of the tail wing is to reduce the body when the wind pressure comes, in detail, because the SUV is in high-speed movement, when the tail wing is not installed and there is no tail warp behind, the oncoming wind will pass through the bottom and the roof, and the air pressure under the car is greater, which will cause the SUV to have a floating feeling when traveling at high speed, which is very unsafe, but the rear wing is installed, When the wind passes over the roof of the car to the roof and finally through the action of the rear wing, the wind will go up or down again, causing the air pressure of the wind to press the car body downward, making the vehicle more stable.

Car modification culture is in motorsports, car modification is to make the car more beautiful, but car modification actually has special functions. The main function of the rear wing of the car is to effectively reduce the air resistance and save fuel when the car is driving at high speed.

The drag of the car in the process of driving can be divided into three aspects: longitudinal, lateral and vertical rise. According to tests, when a car travels at 80 km/h, 60% of fuel consumption is used to overcome longitudinal wind resistance. In order to effectively reduce and overcome the influence of air resistance when the car is driving at high speed, people design and use the rear wing of the car, and its function is to make the air produce the fourth force on the car, that is, the adhesion to the ground, which can offset a part of the lift, control the car to float, reduce the influence of wind resistance, so that the car can drive close to the road, so as to improve the stability of driving.

The shape and size of the rear wing of the car is determined by the designer's accurate calculation, and it should not be too large or too small, otherwise it will increase the driving resistance of the car or not play its due role.

For example, if a car with a displacement volume of liters is installed, the air resistance coefficient is reduced by 20%, and the fuel consumption may not be significantly reduced when driving on ordinary roads. If you drive at 120 km/h on the highway, you can save 14% of fuel.

Many people think that this novel and beautiful car rear wing is a decorative part installed by the manufacturer for the car in order to look good, in fact, its main role is to effectively reduce the air resistance of the car at high speed and save fuel.
