A mystery car was recently spotted on the set of Transformers: Revenge of the Fallen, sending car enthusiasts into a frenzy trying to find out which one it was. Now Jalopnik reports that the car on the Transformers 2 set is actually GM’s Corvette Centennial Design Concept.

Some outlets have incorrectly asserted the concept is a potential design for a next-generation C7 Corvette. They’re wrong. Oh, it’s a Corvette, but our well-placed sources tell us the concept is GM’s Corvette Centennial Design Concept. We expect to see it revealed early next year, months before it debuts on the silver screen in Transformers: Revenge Of The Fallen.

It is not yet known which Transformer the car will be, however some think it could be a redesigned Jazz, while others say it could be new robot Tracks.
