Two-stage panoramic sunroof, to be precise, is a panoramic sunroof. It is a type of panoramic sunroof. The only difference is that the front part of the two-stage panoramic sunroof can be opened like an ordinary sunroof, but the rear part cannot be opened. You can feel the sunshine and scenery outside the car through it.
The panoramic sunroof of high-end luxury cars will also use self-sensing technology, which can automatically adjust the depth of the glass color according to external light. The panoramic sunroof of a car was once regarded as a configuration of mid-to-high-end cars, and it was an important criterion for many car owners to measure whether the car was luxurious. However, as competition among car companies becomes increasingly fierce, panoramic sunroofs are no longer exclusive to luxury cars. Many economical cars are also equipped with panoramic sunroofs.

Advantages of panoramic sunroof:
1. Better lighting: The entire glass skylight above the head is indeed very bright. Especially in rainy weather, at dusk, when the light is not very good, the brightness inside the car is definitely higher than that of a car without a panoramic sunroof. Secondly, cars with panoramic sunroofs also have better visibility.
2. The functionality is also good. When the vehicle is driving fast, the wind noise will be very loud when the windows are opened, but if the side windows are closed and the sunroof is opened, the noise will be reduced a lot while ventilation is provided.
3. The panoramic sunroof also has a ventilation function. When the sunroof is opened when the car is driving, a negative pressure zone will be formed outside the car. The purpose of ventilation can be achieved by utilizing the difference in air pressure between the inside and outside of the car. ?
