What is the plastic below the fog lights of the BMW X1 called?

[AubreyDella]

The plastic below the fog lights of the BMW X1 is called an automobile deflector, primarily designed to reduce the lift generated during high-speed driving, thereby preventing the rear wheels from lifting. If a car lacks a deflector, the difference in airflow pressure between the upper and lower surfaces at high speeds naturally creates an upward lifting force. This not only wastes the car's power but also directly affects driving safety. The BMW X1 boasts a powerful and dynamic exterior design, balancing stability and elegance to showcase a unique style and taste. The interior details are meticulously crafted, with the electronic gear shift lever and sport seats finely depicting a sporty demeanor.
