I'm going to throw it out there that the concept car is going to be something from ford, GM, chevy or whichever american car company dreamworks/bay make a deal with for this film. for god's sake, optimus prime was in chevy commercials while the first movie came out, what would make you think bay would promote $500,000 sports cars? my guess would be the chevy volt or the ford losis...
I say the car used will be a Dodge Challenger. Wait, never mind. If it is supposed to be a Chinese city, then it would make sense that the car be an asian concept car. I say its that new Nissan
Given the GM relationship in the last film (and how well the Camaro Concept went) I'd wager it'd be a GM car. Could even be a Aussie Holden concept -there have been some interesting ones out of their works lately.
Thanks for the news, OP! I can't believe we are only one week away from the start of the TF2 shoot. Leaked designs ASAP please

that is also a firm possibility. it'd be really cool if it was barricade, as some crazy asian concept police car.
