Thanks for the response...however, the procedure you noted does not allow me to get into RS mode. The furthest I can get with the knob is manual mode
Oil temp should be white (above 80C)
1- Traction (ESP) in sport mode
2- Left foot on the brake (press hard & do not press it twice to engage HOLD otion
3- Rotate the knob till RS
4- Confirm by pressing UP shift/ Right Shift on steering wheel
5- give it Full acceleration till it revs to 4000RPM and revving
6- release the brake and enjoy.

just to double confirm...non-PP 63's have the RS feature?

All AMG's with MCT have RS feature
Anyway, I tried another couple of launches under a power-brake start and the results were similar. Maybe it's my imagination, but I think it hooked up even harder when I launched from the power-brake?? Does anyone know how the pro-drivers from R&T or C&D get their test drive times? Also, is power-braking "bad" for the tranny? It seemed like the Race Start function disengaged the tranny until you let of the brake, while the power braking seemed like the tranny was fully engaged, but the brakes kept the car from moving...
Can't wait to get this thing onto a track.
It is just a pity that it takes so many steps to activate launch control and it stops after 4 or 5 seconds. Not drag strip friendly.
I had another thread on this and would like to know if the 4WD model allows power braking past 2K rpm. After some feedback from AMG germany, it seems that they have put this feature (the car will reduce rpm and bog down if you go past 2K rpm) to save the wet clutch.
Now, I would think you probably do not need to do much power braking since you have 4wd and you can mash the pedal without the issue of breaking the tires to the point of burning out. I would assume it would similar to the Audi RS where the car will just launch forward when you floor the throttle.







guess I need to fookin' cowboy up
