Video of the day: The view inside a BMW engine.

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. We've already watched it a half a dozen times and we think you'll do the same.
