windows open/close on opening/closing the door

[onusigep]

I got to test drive a G37 this week. One thing seemed odd.I own a 2003 G35, so please let me know if this happens on new models.

When you open the dor, the window goes down an inch, then when you close it, it goes back up.

What is this for? The salesman told me it was to retain pressure... he's not the most knowledgeable, so I figured I'd inquire here.

It just looked odd. I'm actually kinda worried about this feature here in MI as there have been days when my windows were frozen closed during ice storms and heavy snow storms. I don't want to open the door and have my window shatter or power window mechanicals break.

Can anyone fill me in?

Thanks.

Hmmm... yeah this is an area where I'm not very knowledgable with. The pressure thing seems a bit strange... I've never heard of anything like that before. On my brother's G35 coupe I just always thought that it was just a procedure of letting the person get out or not. The window seems to drop from a "slot" at the top when you want to get out and then goes back in it when it's closed. I think it's pretty cool actually... it's just one of the details that really makes me appreciate what Infiniti has done with the G generations.

Hey, here's an ignorant question, but aren't the doors on the G37 without frames? What I mean is, isn't it just straight glass above the door without anything around it?

If so, I think the sales guy's explanation makes sense. It probably helps reduce air pressure against the side windows upon door closure to some degree that Infiniti engineers think it's worthwhile.

If I had to guess, I don't think this'll affect the long-term reliability of your power window mechanism. The amount the window opens is nearly negligible, and there's some give on those sorts of motors, especially for such a short burst of activity.

Hey, Onusigep, on a separate note, how did you find the car's head room? How tall are you? I'm 6'2" and have a small amount of concern since the G35 coupe was pretty tight. My car will have the sunroof FWIW.

The new Mustang does this as well (at least the GT). This is actually a great feature for cars with frameless windows. It enables the glass to slide into a slot in the roof of the car rather than just make contact with a rubber seal. This prevents easy car break-ins such as by forcing the window down with something like a coathanger. The reason I'm familiar with this is that my current car, a 98 Plymouth Neon is built this way. I've had my car broken into twice uding this method and I even broke into my own car in less than 3 minutes when I locked the keys inside at a gas station. I was shocked at how ridiculously easy it was. At the time I swore never to get a car with windows that had no doorframe around the top. This feature solves that problem nicely!

This window feature was also on my cousin's SL550 convertible...

I'm pretty sure it's because it has no frame, therefore, when the door closes, the window goes up into a slot to keep air and noise out of the cabin

and thus, when u open the door, the window comes down

So what happens if your battery is dead? Can you not get in the car? Have to crawl through the trunk? :-)

I'm 5'10. I didn't even notice the head room. It was plenty spacious to me. I didn't feel any more restricted than I do in my G35 sedan, but I'm not that tall.

For the tall people the sports package includes a seat extender which I'd imagine will make them more comfortable for you tall folks.

I went to see the G37 on Friday and noticed this too. There's no door frame for the window so, like others say, it's going into a groove in the roof frame. Nice feature because I had t-roofs on a previous car and the window rested on a rubber seal. Once the rubber aged, it leaked terribly.
