Silly Question

[Shiny]

Can someone please answer why the window, of convertables & frameless doors, open and close slightly, when opening and closing the door. I have my theories:

• better window seal
• reduce chance of banging against the soft top when closing

but couldnt find the proper reason.

It is for better sealing.

On the coupe you need it to actually go down slightly to allow the door to open easily without catching the window.

It is actually a good design!

is it not so the window does not break when you close the door?

Good design but annoying at times esp if some1 is jumping in and out at regular intervals.

I think more for better sealing...

There are other cars that do it too and not just frameless structures. This is due to the pressure inside a sealed cockpit which prevents easy closure, preventing one from having to slam the door shut.

The reason in they are frameless. So the window has nothing to go into. The action when you close the door is the window pushes up against teh seal and makes a tight seal. Without that you are relying on the window laying flat against the seal with the door pushing it closed.

The 6 doesn't drop the window slightly but I manually drop and close the window. It drops the wind noise at highway speeds.

+1......its to prevent damage or even the glass breaking as far as I know

Actually when they designed the Z's soft-tops one engineer felt a bit bored and he thought to himself; "wouldn't it be cool if the window just drops slightly when the roof open or closed." So they did it.

So for the rest of eternity people will want to know whether it is for a better seal or is it that the closing roof frame doesn't snag on the closed window.

So every time someone asks the question this guy just smiles quietly to himself.:rollsmile:
