Lexus IS-F vs. Audi RS4 Race Video

I’m not sure about the validity of this racing video, in fact it seems downright sketchy, but pitting the Lexus IS-F against an Audi RS4 doesn’t seem like a fair fight at all:

The reason for my doubt is in the second turn, it looks like the IS-F lets the Audi pass, only to absolutely blow by it before the next turn, almost as if the IS-F driver was toying with his opponent.

If this was a totally legitimate race, that RS4 driver was completely humiliated.
