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!
