From C&D 

If there’s one thing that’s not in short supply at AMG, it’s confidence. Tobias Moers, Mercedes-AMG’s chairman and CEO, told us in no uncertain terms to compare the latest version of the brand’s sports car, the GT R, against the Porsche 911 GT3 RS. “Our car is faster,” he said. And when we asked where, the reply was as abrupt as it was unequivocal: “Everywhere.”

What he meant was: the prototype on prototype tires is fast - let's wait for the car they finally sell to customers Smiley

And the GT3RS with equal HP would leave even the AMG "prototype" in the dust... everywereSmiley...When the similarly powered GT2RS comes out ask the AMG again and watch his confidence go out the window. Don't see why they can compare such cars in that sense, AMG never built GT3RS type cars, they are in another niche.
