We first saw the Chevy Trax last week on the set of Transformers 2 in the City of Brotherly Love, but the shot raised more questions than answers. Who was this new Transformer? Friend or foe? Well, today reveals the truth: The Trax will be playing for the good guys in the role of an as-yet unnamed Autobot. We find a certain humor in the fact that we can't tell who just yet because the robot is in disguise; of course, that's the point. We're wondering if Ironhide gets chopped in twain and melted down to make two more fuel-efficient 'bots. After all, we haven't seen the Chevy Beat, the Trax and Ironhide all in the same place yet.

We thought we had all the new vehicles already figured out for Michael Bay's next GM-gasm — Transformers: Revenge of the Fallen. Turns out there are still a few secrets to suss out as a Chevy Trax was spotted running chest to chest with the Chevy Beat moments after the the Bumblebee/Chevy Trax chase shot we saw earlier. Obviously we have no idea which robo-character this little fella will be playing — hey, maybe all the minicars will join together to form Voltron, and we'll have a crazy giant fighting robot crossover movie!
