3. Internal resistance: the resistance caused by ventilation airflow in the automobile, airflow for cooling an engine and the like accounts for about 12% of the wind resistance of the whole automobile.

4. Lift force and resistance force: the resistance caused by the lift force generated by high-speed running is mainly represented by the negative pressure from the rear windshield glass to the tail box cover, and accounts for about 5 percent of the wind resistance of the whole vehicle.

5. Frictional resistance: the friction force of air flowing relative to the car body is about 0.5% of the wind resistance of the whole car and can be ignored.
