Another type of spoiler is inspired by the wing of the aircraft, which is to install a parallel plate at an angle to the horizontal direction on the rear end of the car. The cross section of this parallel plate is the same as the cross section of the wing, but is installed in reverse, with the smooth surface on top and the paraboloid on the bottom. In this way, the car will produce the same force as the lift during driving, but the downward force is used to counteract the lift on the body, thus ensuring the safety of the vehicle. This type of spoiler is generally installed on a sports car with a relatively high speed. Many cars are equipped with baffles and spoilers to improve the performance of the car.
