Crazy how this car puts down traction for a rear wheel drive platform. I do have to wonder about how much better the x-drive version will be overall?

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... This car is going to be so much fun. I'm going to need to get on my tire dealer's good side, because I'm going to be burning through rubber frequently...



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.

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.

Yup, got that part. How does M Traction control level 10 differ from MDM?

“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.

I don't know how else to explain it to you; it now limits/allows the slippage and traction into different intervals from a deviation of 1 to 10 in severity, in a more linear fashion, instead of just on/off as with regular MDM, which was essential 1 - 2.

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.

I'm not sure either. How about this. If MDM were instead an M traction control level, what would it be? 8? 10? 15? NA, they are completely different?

Let's keep it real, ///M isn't the first to offer this. AMG has had 9-stage adjustable traction control since 2017 (AMG GT-R), and the C63 has had it available as an option since their LCI in 2019.

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.

I asked them on Instagram but my guess is MDM corresponds to a setting of 4, 5 or 6. Like somewhere in the middle of the 10-stage range.

I sent an email to BMW and got two very ambiguous answers back. I'm glad to hear I'm not the only one with this question. As a stand alone feature, I (think) I understand M Traction Control. It's how it compares to MDM that it becomes fuzzy. I almost always drive my F80 in MDM. I love it, but there are times that I wish for a little more slip. Many in the US code in "Euro MDM" for that very reason. When I first read about M Traction Control, I was very excited. Still trying to figure out how MDM fits it.

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!

Everyone is guessing. BMW doesn't answer directly. None of the reviews compare the two. I guess I'll just have to wait until I get mine.

I'm relatively unfamiliar with AMG's since I drive stick. Therefore, the two car companies I am most familiar with are Porsche and Bmw because I'm always deciding between those two.

I stand corrected.
