Yeah, this is not the same as on the Cayenne’s AT + eBrake scenario where the procedure is the same as always. EBrake is on, gear in P => Footbrake on => gear in R => eBrake off => Footbrake off => Throttle = eBrake/Hold is confused and releases and engages a few times.

Do you know if hill hold is implemented with the eBrake?
If not eBrake has been 100% reliable/accurate/true over 7 years and 100k miles I’m ok with it and won’t mind it on the G80 but prefer traditional handbrakes to be able to easily rotate the car on snow/ice and gravel roads in certain scenarios. It fits an MT car but for an AT you already give up that level of fine control so it’s a non issue in that configuration to me. |

I doubt BMW was concerned about saving weight in the new G80 because the cars just keep getting bigger. The should have just used a seperate caliper for the parking brake and kept the fixed setup. You're never going to convince me that the puny 1 piston rear caliper does the job well.

Nope - I have had it happen a few times in the work carpark which is completely flat. I think I just haven't pressed the button down the full way or I press it too briefly when that happens to me.
What are your thoughts on someone wanting to retrofit something like this to a G80? Theoretically possible but a complete waste of time I'm going to guess. https://www.ebay.com.au/itm/Ferrari-...MAAOSwdAlemXnS

At the end of the day performance is all that matters. The big M8 seems to have no issues braking with this setup. If the performance of the G8x cars improves on the outgoing models then it's mission accomplished. It all comes down to how much you want to pay for the performance and the shiny parts that are more show than go. Not everyone wants or cares to have the price point raised just so a few people can sleep better about having two piston rear calipers that provide negligible performance gains. If the stopping distances are worse than the F8x we have a predicament. If they are as good or better we don't.

The M5 has had single piston rears since the dawn of time...

Yes but there’s never been a CS before...it’s capabilities need to exceed that of a G8X base and comp. It’s the first M5 with track leaning focus on par with an M3.

They won’t. Pictures confirm that. My point is that if the single piston floating rears are good enough on a much more powerful, heavier and track focused M5 to go nuts around Nordshliefe they are good enough for the G8X

On one hand I think it's a set backwards
On the other, Mercedes even sells their GT-R with sliding rear calipers on the ceramics and no one seems to mind At the end of the day if you are seriously tracking the car it doesn't matter which brakes it comes with, you will need to upgrade |

What advantage does it present? Porsche also uses a floating rear in the Macan, at least the 1st gen. |

The M3 is also under way more price pressure and better spend the budget were it makes a different. |

And budget optimization to use money were they make the biggest difference (not rear brake calipers) sound like engineering lead development. |

If I get one to track I will have to upgrade the brakes anyway, so it doesn't really make a difference to me. |
