Strong Man Franz Mullner Holds Back Shelby GT500

I am not sure I could hold back a moped let alone a Shelby GT500 but Strong Man Franz Mullner of Austria did such a thing as part of National Geographic Channel’s “Humanly Impossible”. Mullner held back the first-gen Shelby GT500 while it was at it’s highest rpm for a little over six seconds.

This is nothing new for Mullner who holds the world record for holding back a Lamborghini Diablo for seven seconds.
