Take a good look at the rear wheel opening. The front wheel opening is directly from the Sky. The rear wheel opening has been smoothed to a sharp lip. I vastly prefer the rear wheel opening shown in the picture, but I assume it is just a photoshop job. It is not just shadowing, as far as I can tell. Whatever it is, I am guessing both front and rear openings will be as per Sky, and not as shown in the picture. I sure wish the Solstice and Sky had those wheel openings.
The also took some of the gap out of the front wheel opening. The joys of Photoshop.
