IAA-C63

I've been experimenting with various ways to use the C63 transmission, and here are my thoughts so far:

- I rarely use C, but it seems fine for gentler driving, and I assume there's a gas mileage benefit. Should this mode be used until the car warms up?

- S seems best when a lot of stop and start driving is involved, or when M is inconvenient (I don't find M worth the bother at really low speeds). I find S to perform generally pretty well, but it's not always able to guess exactly what I want; sometimes downshifts are delayed too much and sometimes upshifts are unwelcome. Does it have an adaptive program which enables it to learn your driving habits?

- I've come to like and use M a lot, particularly for highway driving when I need to do a lot of passing, and for curvy roads where it provides much better control of the car. I'm finding that to get really punchy acceleration, the car needs to be in a gear where the RPMs are about 3,000 to 4,000. With lower RPMs there's noticeable lag, and I don't usually have a need to push the RPMs much higher. At highway speeds, all of this means that 4th and 5th gear usually work best; I haven't even tried 3rd gear, and 6th and 7th gears are sluggish unless the speeds are really high. On curvy roads, 3rd, 4th, and 5th gears seem to cover all the bases.

- I find it a bit annoying to hunt for the mode selection button, since I don't like to take my eyes off the road, and it's not that easy to find by touch. I'd much prefer to have it on the steering wheel, or it least for the button to be raised. I wonder if a raised aftermarket button could be installed instead.

What do you all think? Have your experiences been similar? Any tips?

I always let the car in C until the car warms up.
Don't know if its really usefull but I guess its psychological by now.

55-60 and below i use s d5. wet c. highway s.

S in all conditions.

M most, S Traffic, C never.

what is C?

S for weekdays and M for weekends!

Wow, I guess i'm the only one that uses C pretty much all the time. I hardly ever drive the car hard though so that's probably why. I've had the car 3 weeks now and I've used M mode maybe once or twice. And I'm 20y.o. so I think that says a lot about my self control haha

lol.

M mode kinda suck, it shifts so slow that I don't even use it. Well I use it once in the blue moon to hear the downshift while slowing down. hahahaha

khmergod

If you hard stop from 50mph+ and when it hits 3rd, it burps. Sonic boom for cars around you.

CELLryuu

s most the time but ill throw it into m when i feel like playing around

and i amost always drive in sport mode for the traction control. ive also read that putting it into sport mode unleashes a bit more power....not sure if thats true or not but i do it anyway.

99.9% of the times I use C mode but when I need to race someone I switch to S mode. I hardly hardly shift to M since it is a slugish mode and doesn't really represent a real preformance transmission.
Additionally not having a default mechanism on M mode that allows the car to shift to the next gear in case that you forget to shift up is just an engineering flaw. The S mode seems the best suitable for performance.

DuaneC63

S mode with ESP in sport most of the time. ESP full on in the wet. Drop into M if I want to play around.

That is not a flaw. You don't want a transmission to upshift for you, that's what s mode is for, u can just pick your gear in s mode and it will up shift at redline.

It would be terrible if it upshifted at redline in m mode. Definitely not a flaw. If you're going around a turn and the car upshifts it will upset the balance of the car and you won't have the control of the car you need.

I can honestly say i have never ever driven the car in C mode. Just no interest in it. M mode 80% of the time and S.
I wish it had an S+ mode.

IAA-C63

I completely agree. To me, the biggest single advantage of M is that it won't allow an automatic upshift while driving through a curve. In S, that can happen even if you aren't close to redline.

IAA-C63

Shifts with M aren't race-car fast, but they're reasonably quick compared to a fully-manual transmission, and the benefit is that they happen when you choose, not when S or C chooses. If you spend more time in M, you may come to like it more.

IAA-C63

Wow, four AMG 63s! How do they all compare, especially relative to the C63?

USCGTO

And they are not your run-of-the-mill 63s as well.

Love this line....when I need to race... We just have to do it!

I'm surprised to see the diversity in how people are using the transmission. Primarily C, primarily M, and everything in between. For those who haven't done so, I encouraging experimenting, since you might discover some things you like.

I recently had a long highway drive for business, and the comments in this thread convinced me to give C another chance. For more relaxed driving, it was nice, and I was surprised to see my gas mileage finally get above 21 mpg.

I'm still annoyed about having to hunt for the transmission mode selector button, but I can live with it.

Does everyone agree that RPMs need to be around 4k to get max torque and acceleration?

By the way, I got to drive the Panamera Turbo again yesterday, and the experience reinforced my feeling that the C63 handles better, steers more sharply, sounds better, has better seats, and is generally more fun to drive. My brother-in-law drove both the Panamera and C63 for the first time, and he concurs with me. We have a really nice car!

This thread gave me a few questions.

> Does everyone agree that RPMs need to be around 4k to get max torque and acceleration?

Also wondering this. I had thought the torque-iness of the 6.2L NA engine meant the power was available very low (say even at 2k RPM) but it does sort of 'feel' like the power is arrive more at 4 - 5k RPM.

Also wondering: is it OK to put the C63 in 'S' before it reaches operating temp for the engine? (178 F or w/e the exact number is)... I always leave it in C til then. Obviously I know not to put it in 'M' and rev above 4k RPM's, I guess I am wondering whether it's ok to go UP TO 4k RPM's ('S' mode) under the engine operating temp, or if it's better to stick below 2k RPM's ('C' mode).
