IdeaCity was tired of CGI graphics. They decided to study M engines in Munich, where manifolds were cut, cylinders were shaved and lighting holes were drilled to mount special cameras, lenses and lights.
After two weeks of intensive study and preparation, the team took another four, 20-hour days to film what happens inside the 420 hp mill during a single revolution. The completed spot was filmed at 10,000 frames-per-second and doesn't utilize any form of computer-generated effects. Just awesome, I'm surprised because people go the short cut way or try to make CGI graphics looks so real to impress, but I'm personally more fascinated with the real thing.
