What are the uses of a car sunroof, and why is there only a panoramic sunroof?

First, the design and function of the sunroof are for lighting purposes. To provide better illumination inside the car, the sunroof can supplement the interior lighting. Drivers who enjoy the sun will appreciate the sunroof, but many dislike the bright driving visibility it creates, making the sunroof somewhat of a double-edged sword during driving.

Additionally, the ventilation and air exchange functions of the sunroof surpass those of four windows. When the sunroof is opened, it meets the needs for ventilation and air exchange. However, in cold or windy weather, it can also become too rapid. The wind from outside feels directly on the face, extremely cold, or even chilly. Only when the temperature is relatively high does the entire ventilation process of the sunroof provide greater comfort for passengers inside the car. As summer approaches, opening the sunroof can help adjust the air temperature. When air conditioning is unnecessary, it can lower the interior temperature. During driving, the car can become stuffy, making the ride uncomfortable.

In winter, the temperature difference between inside and outside the car is significant, causing windows to fog up and impair visibility. In such cases, opening the sunroof won't make it too cold and can quickly remove the fog.

Driving on a noisy road, opening the sunroof helps reduce interior noise and prevents exhaust fumes from entering the car. At this point, the air quality inside the vehicle is clearly affected by the enclosed car.
