Michael Bay and his crew have been taking over the streets of downtown Chicago in July filming numerous scenes for the Transformers 3 movie, which is due for release in summer of 2011. With all the commotion from the shooting, it was inevitable that hundreds of people would gather around and capture a bunch of videos from the set.

Some of the Transformer cars that were snagged on film in Chicago include the Bumblebee Camaro, Ferrari 458 Italia, Mercedes-Benz E-Class (most likely the E63 AMG), several NASCAR racers and the topless version of the Corvette Stingray Concept. We’ve pasted the most interesting video clips we found on Youtube right after the jump.
