No the visible carbon fiber panel is not transparent, it does not allow light through. The same is true for the standard carbon fiber panel. The difference between the two is that the 'visible' carbon fiber has been built to show off the carbon fiber which is laid so it looks very good and orderly. The standard carbon fiber panel weighs the same as the 'visible' but is painted the same color as the external body color of the C7. The third panel option is the transparent panel, as the name implies it allows you to both see in from the outside and see out through the inside creating a very nice open cabin effect. The confusion to some comes from the fact that both the 'visible' carbon fiber (which does not allow any light transmission) and the transparent panel look almost identical (both look almost black) from about 3 or 4 foot or more away except for the 'visible' carbon fiber panel has the side spears painted body color while the transparent panel is totally black in appearance from 3 or 4 foot away.
