To be perfectly clear (as Audi has asked us to kindly spell it out in big bold letters for non-advertising people who may not know what the word "spec" means) - a SPEC ad is an ad not paid for, nor approved by the brand that is depicted in the ad.
This ad is thus, not an official Audi ad. It doesn't run anywhere. It's an ad created to show off the directors skill. There are better examples of suicide by car commercials though as I have pointed out in badland.
