There's no rule that says a "coupe" has no window frame and a "sedan" does. I have a Subaru WRX STI which is officially a sedan, yet all four windows are frameless. They also don't roll down when opening or closing. They just work, and in the 20+ years I've owned Subarus with frameless windows, I've never had an issue with leakage, noise, nor have I had difficulties opening or closing the doors.
- jiveturkey 4y agoYes, I'm speaking broadly when I say coupes have no window frame. There's not a universal definition of what makes a coupe and what makes a sedan. Some say 2d vs 4d but that's not true either. It was useful for my response to classify coupes in that way. Your STI (great car BTW) is only "officially" a sedan by Subaru's nomenclature and marketing position of the car, not by some global standard or definition. Different cars have different air-tightness of the cabin, different interior volume, different door pull designs, and different door weights. It's these factors combined that dictate whether such window shenanigans are useful or not. Not just the inherent limitations of sealing the glass against the roofline. The major point of my response was that Tesla's claim (per the post, I didn't verify) that this is needed or useful to somehow improve the longevity of the weatherstripping, is nonsense. However, there are other valid reasons for this behavior.
