It will blow out. At 65mph, the outward pressure is about 10 pounds per square foot. My bimmer hasn't been redelivered yet, so I don't know the sunroof dimensions. But say it's 3' by 2', that gives 60 pounds of force on it. Not much, so either the glass is defective, or maybe it was mounted incorrectly such that it was under a lot of stress.
For a sunroof to blow out due to cabin pressure....., that must of have been one hell of a fart.
