That's one consistent feedback for sure, it puts the power down very very well

This video seems to provide a very clear explanation for why the G80 puts down power so much more effectively than the previous generation. Essentially, it seems to be down to a faster reaction time to changing CoF.

pretty wild they went down his much of a rabbit hole with developing the RWD traction control system with AWD model in the pipeline, impressive I have to admit.

And they also limit full torque being available in lower gears at lower speeds.
But I don't mind that at all. And I'm so psyched about the 10-stage traction control. I can't wait to teach my girlfriend and niece how to drift with this new BMW system, since both are so very interested in high speed cornering and drifts. This new M will make it quite easy for them to get the hang of it. Brilliant, BMW, brilliant... ![]() ![]() And if Pirelli's come on my M, they won't last long. I'm going to burn those babies down to the chords at the track, with my Michelin's waiting in the wings. ![]() |

I would be willing to bet the AWD model also benefits from all of this research and tech. Where the RWD model has engine, trans, individual wheel brakes and the rear diff as levers to control the car, the AWD model adds the center diff to the equation to help balance the power front and rear. As I understand it M xdrive does not run separately from the traction control, just like the M diff on RWD models it is an integral part of the traction control.

I think M division learned their lesson with the F80's terrible traction issues, that a more dynamic traction control system was necessary to control all that power. It also helps that they totally shifted the low end hp/tq to the midrange (once the car is at speed).
There's really no way to cure the problems with the F80's power curve although getting the GTS engine tuning does help a bit. |

These guys really are insane and I really do love them for it. No one else is doing this.

I'm still confused how this compares to MDM. Yeah, M traction level 1 allows for way more slip. How about levels 9-10, how do those compare to MDM?

The braking, traction, e-diff, ect. is now all electronically actuated, instead of hydraulically controlled, which now allows them to individually modulate the vehicle's stability and traction with a lot more precision and end-user fine tuning abilities.

“Integrated actuator contiguous wheel slip limitation.”
So that’s the secret sauce. I’d like to see a sketch of that to understand more of How this differ from the F8X limited slip M eDiff? Has TC moved into the eDiff as an integrated solution? As for MxDrive I’m sure it can take full advantage of this new/improved feature in the same way it does include the M active differential on the M5.

Since the brakes are now electronically actuated, the slippage, yaw, vehicle angle, ect. can now be instantly modulated, allowing for a higher-level locking intervention to stabilize and enhance the vehicle's dynamics. Google the words "BMW DSCi" to learn more.. https://www.press.bmwgroup.com/globa...rs?language=en . |

It does help explain why the G80 is so much more planted than the F80 for sure though. This is definitely the greatest improvement generationally from F80. |

Will I stop using MDM all together since now I can fine tune the setting? Are they completely different?

I'm not planning to track this car, so I didn't get the "M drive professional" on my build. I've looked through the menus and I'm guessing MDM offers me a 5 on the 0-10 scale of the traction control.
So basically 3 settings instead of 10 in this spec? (on - 5 - off) I have to say I'm a little more confused after watching this video than before. Does anyone have any additional personal experience or insight on the other setups not covered in the video? Thanks in advance! |
