Update: From the comments and twitter, readers are saying the car is either a 2002 Cadillac Cien Concept, a car that Michael Bay used in The Island. Others are saying its 2014 Cadillac Cien Concept. Which year could be important as I doubt Sideswipe would be a 2002 but could see him as a 2014. Of course neither always remains a strong option. Its just hard to ignore it being a near identical shape and color as DOTM vehicle. It would fit the character the same way the other vehicle changes still match the overall expected look for the character's vehicle mode.
