Two guys are lost in the desert in Fiat’s global ad campaign “Mirage.” A four-door Fiat drives by and the pair dismiss it as a mirage, as the song “Happy,” as performed by Pharrell Williams pays in the background. A second Fiat comes up to the men — this one with Harlem man Sean “Diddy” Combs inside, offering the men water. Clearly, another mirage, right? Au contraire. The lost duo eventually stumble upon a desert party, hosted by Diddy — but are still convinced it’s all a mirage because Fiat doesn’t make four-door cars. They do now. The ad promotes the Fiat 500L using the tagline “Unbelievably Big.” See it here, created by Doner.
