I do have the shift assist feature turned on. I know it plays a welcome role in smooth downshifts. It may play a role in smooth up shifts. I have not bothered to turn it off to find out. I like the way the transmission shifts and if shift assist contributes to that I'm ok with that. I have recommended a new owner experiment with letting the clutch out smoothly/slowly with the engine at idle with no extra throttle to get a feel for how the engine controller will work to keep RPMs up. This tends to reduce the fear of stalling the engine. That you are experiencing some shudder/feeling like the engine is bogging suggests you are not as smooth with the clutch as you need to be when doing this experiment. I say experiment but I also rely upon this technique when pulling my car out of the garage as I have to make a sharp turn immediately. So I want the take off to be smooth but slow. Likewise when I go to back the car into the garage. I want to slowly back the car and get it into the garage with no drama. I also use just the clutch with no throttle when I pull into a parking space and when I pull out again. On the road though I give the engine a bit of throttle just enough to raise RPMs to ~1K and simultaneously let off the throttle while smoothly letting the clutch out. The car moves off from a stop smoothly with minimal clutch slippage. The kinetic energy the flywheel has from this extra bit of RPMs is sufficient to get the car moving. As the car moves off at the proper time of course I apply some throttle to accelerate the car. The transition from being stopped to moving off to accelerating to whatever speed I desire is very smooth. This has been my technique for decades and I have never worn out a clutch, even to 150K miles and beyond. (Well one car's clutch did manifest behavior that indicated it was worn out -- the clutch pedal required excessive effort to depress -- but this was at 317K miles.) Smooth engagement coupled with letting the clutch out neither too fast -- shuddering -- or too slow -- excessive slippage -- is the technique you are after. As this is your first manual transmission I will add as others have offered practice practice practice. As you practice focus on identifying bad habits/sloppiness and work to eliminate them. You want to develop good "muscle memory" so working the throttle/clutch to get the car moving smoothly and smooth shifting up or down becomes automatic (no pun...). |

I agree with your DCT comment. That is why I ended up with a 6MT G87. If it came as a DCT paired with the S58, it would be a no brainer as BMW has disregarded to upgrade their manual platform in over 10 years. |

Thank you. I am a true enthusiast! BMW actually called me yesterday and tell me thank you for being so loyal and having SO many M cars over the years. First time they have ever done that for me. It was cool. Oh yea, DCT is KING to me. DCT or PDK all day for me. The AUTO is as close as I can get so be it. It is what it is.

Still bothers me that they went with a torque converter, but it just goes to show that if you want the DCT feeling, it’s still achievable. Maybe warranty won’t like it |

Well, I dumped my 3 week old 6MT today. I went back to paddles. The 6MT was fun. But I did one 2hr bumper to bumper drive down the 5 south from OC to San Diego and that just ruined it for me.
I had a gorgeous FPG with silver wheels. But I’m happy to be out of the manual and I’ll never do matte paint again. The fear of one scratch just made me so paranoid to enjoy how gorgeous it was. And if I was going to PPF it, I’d rather have a normal color and make it matte. That way I could have best of both worlds. Anyhow, heres the new one. And old one side by side. New one isn’t as pretty, but I’m happier overall.

I’ve had a lot of MTs in the past and driven them for decades blah blah etc etc. I sometimes still have trouble in this car for some reason starting off smoothly. I either under rev and get the chatter or over rev and slip the clutch too much from time to time. Need to do the clutch stop and CDV delete me thinks.
Agree with BIGW0RM about the F80 DCT. If this car had that option available it would be my choice. |

Starting from a stop by only releasing the clutch (no gas input) is only to demonstrate that you stall the car when you let the clutch out too quickly. Most new drivers will add gas, hear the engine rev, and quickly release the clutch, stalling the car. Once you get a feel for the proper timing to let the clutch out, you should be introducing throttle at the same time while releasing the clutch. It's a delicate balance that takes practice.
The only time I tolerate some clutch chatter/judder is when I am reversing and move the car by releasing the clutch only. I do not need to move that quickly to introduce throttle. First to second gear is going to be jerky, especially if your variables are different techniques each time you shift from 1-2. The correct amount of clutch slip from 1-2 means clutching in (in first) at the same speed, letting the revs drop the suitable amount, and then releasing the clutch. Consistency in your variables will help you learn how to be smooth by changing a single element at a time.

The shifting from 1st to 2nd is truly a thing with the M2 (both F87 and G87). Generally the shift will be seamless, however from time to time it will catch you out and the shift will be shocker...perhaps we should put this down as a character trait with manual M2's.

This all said, I personally love that I have a 6MT M2. But I work from home and don't need to drive this car unless I feel like it. Got the car in Mid-August, went out of my way to put 1200 miles on it by end of October, and I have 1350 miles today haha |

So I'm sticking with the stick. I have an i4 M50 so if I don't want to shift, I'll take the EV. I also work from home so the M2 is completely a "fun car". No chance in hell of me getting paddles. Now I just need that allocation to come through.

Yep, that was my stance. If I needed a daily I'd feel different but since this isn't my daily I want to row my own gears, even if it's got some minor annoyances and isn't the fastest version of this car.

Practice. Give it gas in first for sure. I'm not sure when you are shifting in terms of RPM, but I've found that in first and second getting up there to 4-5K reduced the "jerk" quite a bit when shifting. That's being said I go with lower RPMs until the engine is up to temp.
But mostly this is practice. I've been driving manuals for 40 years and even changing from one car to another takes practice. |

I’ve been driving a manual since I was 18 and I was so embarrassed when I did the drive in the M2 when picking it up with my CA. It was sooo jerky.
