Laurel and Wes from the MTV show “The Challenge” drive up to a Sonic, and Wes is stunned by the Transformers-themed Slushes that the restaurant is offering. He seems certain the the couple is “so Team Optimus” and that they’ll be the challenge champions of Sonic, but Laurel isn’t so sure. Optimus Prime and Megatron shout out from the drive-in intercom, warning them that all is not as it seems. Laurel doesn’t take it too hard and tells Wes to just consider it an “elimination round.” Customers can enter the Transform Your Summer Sweepstakes for a chance to win prizes by purchasing one of the limited-edition Slushes. “Transformers: The Last Knight” hits theaters June 21, 2017.
