Does the BMW X4 have frameless doors?

[StLuna]

BMW X4 does not have frameless doors. BMW models with frameless doors include the BMW 2 Series, BMW 4 Series, BMW Z4, BMW 3 Series GT, BMW 5 Series GT, and BMW i3. Advantages of frameless doors: They look stylish and sporty, with good sound insulation. The frameless door system automatically lowers the window by 0.5 cm when opening the door, and raises it to seal against the weatherstrip after closing. Since the weatherstrip is installed on the car body, the sealing performance is excellent. Disadvantages of frameless doors: Compared to conventional framed doors, frameless doors have higher manufacturing technical requirements, such as for sound insulation and waterproofing, resulting in higher production costs. The complex technology also increases failure rates and maintenance costs. For example, with frameless doors, only the door panel bears the load, which over time can cause loosening of window or door panel components, leading to air and water leaks. Therefore, their durability is not as good as that of framed doors.
