Okay, sure, we don’t REALLY know which new Transformers will be appearing in Michael Bay’s Transformers 2. But we do have photos of new concept cars running around the TF2 movie set.

So lets take a look at the alt modes of some of the autobots and decepticons you might be seeing on the big screen come June 2009.

A red/orange 2009 Chevy Trax was spotted driving down Front Street with Bumblebee and the Chevy Beat that has been previously seen at the Smithsonian set. Since they have been seen at multiple locations traveling with the Autobots, I’m guessing they are part of the team.

In our first Transformers Secrets Revealed article we told you about a new set of Autobots featured in the opening sequence. An old beat up ice cream truck split in two to form two smaller Transformers called The Twins. But we haven’t seen the Ice Cream Truck back in action since the Bethlehem Steel shoot which leads us to believe that The Twins might have found a new auto form, possibly as the Chevy Trax and Chevy Beat. But then again, that might take away from the coolness of two Transformers which combine together into one vehicle. Its also worth mentioning that there is one more car in the Chevy line of concept cars that hasn’t yet made an appearance, The Chevy Groove. The photo from the set comes from jalopnik.

Check out the rest of the unconfirmed line-up after the jump:
