Cd without area is not that useful - they can make the # look good by using a large area, or conservative by using a small area.
Fortunately they published that a while back in a press kit : CD = 0.28 and Aref is 2.20 sq. meters.
EDIT : whoops - that area is for the A4 - probably use the same for the S4, but I can't be sure...
