I thought it was Allan McNish at first, but I don't think it is now.
According to the youtube comments...
Fabulous car! And by the way - I am not completely sure - this is Sport Auto test, so the driver might be Horst von Saurma, and he isn´t a good driver, he´s fabulous. He is the man who lapped Zonda F at 7:32 round the ´Ring.
EDIT: Oops, my ownage of the R8 doesn't count because it is a manual tranny, and not the DSG. I was about to say how much quicker I can shift than that DSG...
