Fiat’s new global ad campaign stars Diddy and sets Pharrell’s Academy Award-nominated “Happy” as the background tune. The new ad “Mirage” finds two men stranded in a dessert, unable to distinguish reality from hallucination. In their journey, the guys encounter Diddy who offers up a bottle of his brand water, Aquahydrate. The commercial culminates in a Revolt soiree, where the struggling men notice a change in the new Fiat model car.
