What is the function of a car front lip?

[DelCassidy]

The functions of a car front lip include: 1. It can perform overall vehicle streamlining; 2. Reduce airflow passing under the vehicle; 3. Improve vehicle stability; 4. Enhance the aesthetic appeal of the car. The overall vehicle streamlining ensures that air flows evenly from the front to the rear of the car, reducing frontal turbulence, which can lower the cd value and increase front-end downforce, with more noticeable effects at high speeds. Reducing the airflow under the vehicle can decrease the lift caused by the airflow beneath the car. Generally, the higher the vehicle body, the more unstable it becomes at high speeds. Modifying the car front lip alters the car's appearance and requires registration with the vehicle management office; otherwise, the car may face difficulties passing the annual inspection.
