Thank Everybody for your positive comments
x LEXION: there were about 6 FXX + the FXX Evoluzione 8)
x dani_d_mas: the sound was similar, but it was faster of a normal FXX.
There was a moment in which the FXX Evoluzione has braked...It did half circuit with the brakes glowing
PS The sound of the FXX Evoluzione is simply fantastic! 8)
Bye
