I understand that it's much more than just the sunroof (also the frame, motor, and perhaps extra roof bracing) but does it really increase the weight that much? Thanks.
That was me. I knew that the weight of a standard-sized sunroof is around 40 pounds. However, until seeing spijun's spec above, I was just guessing that the panoramic one was at least 100 pounds. At nearly 230 pounds, I was way off! Thanks spijun! That is substantial!
Now, I'm guessing the weight of the metal that it replaces to be around 30 pounds, so let's talk about those 200 extra pounds...they are on the roof! For a simple demonstration, strap 200 pounds to the roof of any regular-sized vehicle and see if you notice it. I do have a couple of minor complaints about my (still new) SQ5, but the panoramic sunroof deletion isn't one of them. After driving both, I am thrilled that I waited the extra time to get one without. It's not so much the acceleration (although it is most likely the reason for my bone-stock, 0-60 time of 5.0 sec.), but the handling is noticeably, greatly improved. Aesthetically...I'm kind of a cave-dweller, so I really like the darker and cooler interior.
spijun: I'm starting a new thread that I would like your technical input on, regarding the noticeable negative camber at the rear wheels.
