On paper the new W213 Mercedes-AMG E63 S is the most powerful car of this trio. Mercedes-AMG rates the new E63 S at 603 horsepower and 627 lb-ft of torque. Now, depending on whose horsepower rating standard you use the RS7 Performance edition puts out up to 605 horsepower and 553 lb-ft of torque.

The power is basically a wash but Mercedes-AMG is getting much more torque out of their 4.0 liter V8 for whatever reason.

The Nissan GT-R of course has a 3.8 liter V6 and while it is also all wheel drive like its challengers it has a dual clutch transmission. It is also the lightest of the three.

It is surprisingly close but the GT-R pulls all three on the top end.

No trap speeds as usual (wtf?) but the GT-R wins with the E63 S close in second.
