Maserati GranTurismo MC Stradale - downshift, acceleration in a tunnel

After my photoshoot with this Maserati GranTurismo MC Stradale and a Jaguar XK-RS, we went back home to the dealer and we drove through a tunnel. I have decided to made a small video of the sound of the MC Stradale - here it is! Facebook: Thanks for watching, Keno Zache
