Spy Shots: Mystery concept caught in Spain

Autoblog Quiz of the Day: the minicar pictured above was spotted in Barcelona, Spain at Central del Poblenou Park, during what sounds like a photo or commercial shoot. Two people were caught driving it, the one in the sky blue outfit and hat looks to be a model/actress. The car, devoid of any logos or identifying marks, was accompanied by several trucks with French license plates – along with about ten people who didn't appreciate the person taking photos. Can anyone help us solve the mystery? Check out the image gallery below, and leave your guessses in 'Comments.'
