Audi commercial shows a depressed man attempting to kill himself with carbon monoxide poisoning. After several hours, the man awakens to find his A5 has run out of diesel and he is alive and well. Disappointed, he attempts to sever his head by using the power windows.
This Audi commercial is virtually identical to a 2002 ad created by the king of dark comedy Brian Baderman for Citroen. In that commercial, a man also attempts to kill himself in the same way. When it fails, he drives the Citroen into a tree.
