Since 1964, Porsche's Ultimate Factory in Stuttgart, Germany has made one of the world's most iconic sports cars - The Porsche 911. The factory runs like a precision machine as it builds more than 200 of Porsche's legendary flat-six cylinder engines a day. In the body shop, 105 robots and teams of human welders build the Porsche 911's body. The color coat for all bodies is hand-painted. And finally the cars pass through 117 assembly stations, the most dramatic of which is the "marriage" of the body and powertrain. By the end of every workday, 110 new Porsche 911's roll out of the famed German maker's Ultimate Factory (Mega Factory).
