There have been several threads in these forums where people have attempted to compare the production and release candidate cars to the original reveal alpha cars and computer renderings. One of the things people have to be careful of is using pictures taken from different perspectives. Here's an example I've used before. Compare these two pictures. They look different, right? Two different cars? Nope. These are two pictures taken of the same car, on the same day. The top picture was taken from fairly close. The front & rear of the car appear to be shorter. The wheels look a bit oblong. That's not from a "bad" lens. That's due to the close perspective. The bottom picture was taken from far away, using a telephoto lens. The car looks more two-dimensional. The front & rear overhangs appear to be longer. But it's all due to the perspective.
