I tried what Matt said... didn't work!
I read in one of the threads that we can get faster takeoffs if we switch to manual and put the gear on 1 when the car is stopping. that will make the car gets into the red area in the RPM and I think someone said it will cross the red area.
well... this morning I tried it... Once it reached the red area it shifted gears like if it was on auto. it didn't enter the red area.
It kept shifting till it reached third gear I think.
so?

Thats because the tranny is software controlled and MB has added safety features that won't let you hurt the drivetrain. Remember that you have tolerances in all components. Therefore one might get slightly into the red area whereas someone else will not.

Ummm... not for nothing but two points...
If you wanted to hit redline and get faster shifts, you should have gotten the manny.
You shouldn't be going into the redline. Up to is ok, beyond really ins't. Not sure about the gearing with the Auto, but with the manny, our peak rpm curve ends just before redline, literally just before it, so you should be shifting around 5700 or 5800 rpm if you can anyway.

Matt who?? Me? I don't think I ever posted that. If I said anything, it was probably exactly what you experienced. That you should put it in 1 and not worry about shifting it yourself. Just let it get to redline and it will shift automatically. This or leaving it in D is the best way to go fast. If you try to shift it yourself, you have to time it just right so it will shift right at redline.

FWIW, the manual won't let you mess with it either. Same deal, in Neutral or out of gear, 4000 RPM is max. When running it hot and rowing through the gears, it doesn't let you over rev past the beginning of redline. The engine computer just puts a chill pill on the throttle... most disconcerning!

I played with this sorta thing just today on the way back from Michigan. The best acceleration was from having the gears shifted down and then letting the car upshift when it needed (about 6000 rpm).
It was almost as fast when starting from D, but the tranny tended to want to upshift a bit too soon even when the accelerator was mashed down.
... wife said that i don't need to go 95 to merge with traffic, but i had to play it safe ...

There's no need to go past redline because you start to fall out of the power band. It's best to just shift and get back into the big wide power band that most MB's have.

Ok I read you other post so you have a C200k and want to put 18” rims you can kiss what ever power you have after the rims. Your car is probably going to be as slow as a snail.
And some personal experience with my car it has 215 HP and 290 pounds of torque. The redline is at 6k. Most of my power is at the low rpm if I rev the engine higher than 5k it doesn’t get more power it slows me down. My sisters car the redline is at 7k rpm the pick power on the car is at 4K rpm and the power drops off at 6K
