What traction mode do you use?
Historically I've used mdm.
I've been meaning to play with the 10 stage traction so today I put it on 8 and drove it around. I immediately noticed (I could be wrong) the shifts with the zf have much more of a kick in the butt than I'm used to with this car, I was a pleasant surprise to say the least! Am I imagining things? Anyone else here played with the 10 stage settings much? |

I have only played with this on the track. Call me cautious, but I prefer not to turn off traction at all on public roads.

From BMW
M Traction Control and MDM are different functions, hence there is no M Traction Control setting which equals MDM. Simply spoken, M Traction Control is a slip control mechanism that controls rear wheel slip in 10 stages when DSC is switched off. Level 0 is OFF and allows for unlimited wheel spin. The higher levels allow for very limited slip. The slip is controlled using the engine‘s rpm as the only parameter. The vehicle’s yaw rate is not a controlled parameter here. In contrast to M Traction Control, MDM is a part of the DSC mechanism and actively controls the vehicle‘s yaw rate. DSC/MDM use engine power controls as well as brake interventions to stabilize the vehicle dynamics on the road. MDM uses M Traction Control levels 4 to 7 depending on yaw rate behaviour. I believe Stage 9 is for track and Stage 10 to protect the Rear tires and bring them to appropriate temperature. Found the documentation here Last edited by mzcp; 10-19-2021 at 01:19 PM.. |

Interesting as on my X drive I can not adjust the traction unless Im in DSC off (cant use mdm at all). Then I run 5 on a dry day after the tires are warmed up.
I didnt have this option on my RWD car prior so it was always MDM.

You need M Drive Pro to tinker with the 10 Stage Traction Control. Sorry I assumed the OP had that option.

I have the M drive pro but on the x drive its shaded out unless I go to DSC off 2wd (I can not use the traction under MDM)

If I recall from one of the BMW videos this is correct, you need to have DSC off to use the 10 stage TC |

In the xdrive if you push the traction button once for MDM you get 4wd sport. Need to go traction completely off to access the 10 stage (if you have the M drive) as others have said.

I'm really surprised some guys are super afraid to turn the traction fully off. That's the fun of driving a rear wheel drive car. By no means do I consider myself an expert. I just take it slow to get to acclimated so I can learn the car and slowly push it more and more every time. That's the beauty of learning your new toy.

I am with dimab0 here. On the street, I am in DSC on, cause I don't need to drift around street corners, I get much more satisfaction launching off highway on-ramps to 130+ than screeching tires. Also, curbs, cars, and people are things I don't want to interact with physically.
However, on track, I started with DSC off and MDM on 10, 8, 4, and 0 all within a few laps because coming out of a corner - the throttle would be severely limited as the car accelerated at the edge of traction. I found all but 4 or below to be almost impossible to get the car to slide. I guess I am getting old, breaking the tires loose in the street doesnt do it for me anymore. I am much more focused on track driving, and getting faster and more comfortable with driving with slip angle around track. Its very challenging to drive with all 4 tires slipping and throttle steering out of corners...
