A yellow Saleen S7 was spotted on one of the Transformers 4 sets in the Detroit area. So far we just have the one image so hard to tell if its part of the movie, a background prop or maybe could even just be a rental for a higher up attached to the film.

In addition, below is a video of maybe Mark Wahlberg piloting what looks look like a Cybertronian vehicle similar to those in Dark of the Moon and photographed earlier this month. Again, no clue what is being filmed but the green screen indicates it will be composited in later by ILM into a bigger scene. Thanks to Kenny.D for the links.

Update: Video pulled due to takedown notice by Paramount. Considering the video was taken from a public location, Paramount has no legal claim (otherwise the paparazzi and showbiz shows and sites would be out of business). Sadly the Google bots do not know this and I guess the video poster chose to not contest it.
