Several months ago,Porsche accused GTR of cheating on the Ring,and soon Nissan replied them.

And now ,we know that Porsche still keep silent after Nissan hit back Porsche's claim.

If Nissan is really cheating,Porsche must have enough evidance.They have a GTR,and they can test it anywhere,anytime,anyhow they want.I think Porsche know the GTR much better than us.

But Porsche havn't say a word a again. I don't know why.
