    • Mercedes-AMG W205 C63 AMG S Coupe Nurburgring laptime - 7:44.13

      A 7:44.13 is not bad but it sure does make you scratch your head as to what magic Mercedes-AMG is using on the AMG GT 63 S 4Matic+ 4-Door Coupe to get a laptime almost 20 seconds quicker in independent testing.


      The C63 S utilizes a 4.0 liter twin turbo V8 after all and the C63 Coupe is 700+ pounds lighter than its big 4-Door GT brother. That weight difference alone you would think would negate the roughly 20 second disparity yet here we are.

      Mercedes-AMG clearly put more engineering into the track prowess of the big four-door than they did the cheaper 'entry level' M177 powered AMG C-Class.

      For further context, a BMW F80 M3 Competition was timed at 7:38.

        It would be nice to see a comparison of the Gs and cornering speeds of this and the GT 4-door. I wonder if it's carrying less speed through the corners, accelerating out of corners slower, slower on the straights or all three. 20 seconds is an insane difference.

        The Nürburging is a high-speed track, so that a weight disparity can be compensated to a certain extent by additional hp.

        That being said, the more you approach the 7-minutes mark (which is far, far from the C63's run here), the more important suspension, tyres and aero become. That's why the McLaren 720S tested recently did not tap its full (hp) potential as opposed to a track-optimised GT2 RS with roughly the same output.

        I haven't read this particular supertest yet, but sport auto does provide info on max. g-forces (which obviously depend mostly on the type of tyres used) and also max speeds in each section of the 'Ring. I would expect that the far heavier GT 4-door can compensate its weight further due to its 4-wheel-drive, the C63 is known for being short on traction at lower speeds due to the immense torque output of the M177.

        Not enough people pay attention to this.
