This small mp3 is the sound of a 10-cylinder, 750 horsepower Asiatech F1 engine warming up. After a few seconds you will notice it sounds a little strange... that's right, it's playing "when the saints go marching in" with its revs. it can do this because in F1 cars these days the accelerator is computer controlled, so they programmed the computer to have a little fun, much to the amusement of the reporters and pit crew.

Thanks ZZZ Online!
