As I'm pretty sure everyone will agree, all car-makers have their secret prototypes which may end up on the cutting room floor without ever being revealed to the public, not Porsche though, they're happy to reveal the list of their Top 5 prototypes.
It's not every day you get to see behind the scenes of one of the worlds greatest motoring manufacturers, pulling back that curtain to see what goes on in the minds of their product developers. It's exciting stuff, this, if for nothing more than to see the thought process of how they select the products that they take into production.
This list of the Top 5 Porsche prototypes does just that. To be honest, I'm happy to see some of them didn't make the cut but others could have been really cool!
Hit play and enjoy the show.
