Simply a GM vid of their cars in Autobot guise driving about in different locations (Noticably a lot of deserty ones and an AFB at the end).... but the combinations of Autobots we see could be an indication of how they team up in the movie

Most noticable is the amount of shots with Skids, Mudflap and Bumble Bee (Camero/Beat-Spark/Trax)
