Is a panoramic sunroof equipped with a sunshade or a sun visor?

A panoramic sunroof can be equipped with either a sunshade or a sun visor, depending on the usage scenario. Below are some drawbacks associated with panoramic sunroofs: Prone to turning into an oven: While panoramic sunroofs offer an excellent sense of openness, direct sunlight entering the cabin can significantly raise the temperature. Difficulty in noise control: The thin glass used in panoramic sunroofs provides less insulation against external noise compared to traditional roof linings. This results in noticeable wind noise during driving, and the sound of rain can be even more directly transmitted into the cabin. Susceptibility to leaks due to aging seals: Compared to standard sunroofs, panoramic sunroofs utilize larger sealing strips and adhesive bonding. Over time, improper maintenance, such as prolonged exposure to sunlight, can accelerate the aging of these components. Additionally, unlike conventional roofs that rely on drainage channels, panoramic sunroofs primarily divert water along the surface of the bonded areas, lacking dedicated drainage pathways. This design can eventually lead to water leakage issues.

This question reminds me of the time I researched while helping a friend pick a car. Most panoramic sunroofs come with sunshades, which are fabric materials that automatically roll up like curtains when you press a button. Some high-end cars use multi-layer sunshades, with an outer layer of thin gauze to block UV rays while still allowing you to see the stars, and an inner layer of thick fabric for complete light blockage. I've driven cars with sunshades, which are hard plastic panels that slide manually, but this design is mostly phased out in new cars priced above 200,000 yuan now. It's best to test it out when choosing a car, as some sunshade tracks can become sticky after three years, especially for cars often parked under trees where tree sap can cause more trouble.

As a veteran driver with ten years of experience, I've used both sunshades and sun visors. Nowadays, panoramic sunroofs uniformly come with electric sunshades, with the BMW 5 Series' honeycomb-style sunshade being the most practical—it doesn't even make your head hot at noon. I remember one summer driving a friend's old Tiguan; the sun visor was so hot you could fry an egg on it, and it still let light in even when closed tightly. The new electric vehicles from emerging brands are even more impressive. For example, the XPeng G9 allows voice control to adjust the sunshade's opening angle—opening it halfway is most comfortable when the sun is at an angle. If you smoke and open the sunroof, remember to close the shade first before opening the window, otherwise, the wind rushing in will make the shade flap loudly, which is really annoying.
