I'm skeptical that these are real. Just the placement of the badges on the rear are so bad that I have a hard time believing any respectable car company would even consider it. The black extension thing to the rear window is such a bad idea I've never even seen tuner guys do it. The rear end looks so very Korean anyway. When something looks Korean that generally means it's horrible. There's absolutely no congruency between the front and rear ends, and that's important, because when elements flow throughout a car's design then it looks like a pro did it, instead of a 10 year old. If they had designed the rear as well as the front, and as well as the XF, they'd have scored a 10.
If these pictures are real then I feel very sorry for Jaguar, because they have just failed miserably.
