If you take 7th picture from
http://www.f30post.com/forums/showthread.php?t=651508 and flip it then you can see that it is wider. For some strange reason I have feeling, that some renders are just artist's fantasy as they are off even if posted after real spy shots which reveal quite a lot. This one is actually not disturbing as much as many others. Just for fun and comparison I added horizontally flipped picture from above mentioned thread (that is why exhaust is on wrong side and text is backwards).
