8 Series (G15) [Official] BMW 8 Series Coupé (G15)

Yes, that's correct. But the biggest advantage of having the turbos in the hot V is the cross feeding of the turbos in order to have equal impulses. There are too many negatives of this arrangement(hot V) and I wonder why VAG and MB do not use the cross feeding. Maybe the packaging allows for some modern suspension technology that requires mo...

I agree about the advantages of the cross-flowed manifold but it must be pointed out that only the S63 employs this feature and not the N63 [to the best of my knowledge.]
There are other advantages - especially in terms of engine bay packaging - of the hot vee arrangement without the need for cross-flow to be mandatory.

Till now I lived with the fallacy that the N63 also has this system. Thank you for clearing this for me.

You're welcome. Now, maybe you or another member can help me - I am under the impression that BMW patented the cross-flowed, pulse tuned manifold & turbo arrangement. Can this be corroborated?

my friend’s new 850:

Currently considering a RS now that prices aren’t so ridiculous. Discussion for another thread.

What color is this? Is it azurite black or tanzanite blue?

I believe your knowledge is correct...

Not easily in my experience. A Simple patent search reveal lots of similar articles.... this might be it ...

But frankly, being somewhat familiar with the ways patents are written, and not reading german fluently, I'm not that sure. I'm tired as f*** at the moment, but something in my head is saying that this is relevant because the it's "twin scroll", which is something else BMW have patents on also.

Love your work, as always, Matski. Thank you.

Bwahahahahaha! Finally, someone who can relate. Quite possibly the worst song ever made.

So that might just explain why the M850i sounds so much better than the M5.

I’m just loving the M850i

Klier’s world exclusive for germancarforum.com

Below is a screen shot of the wheels on the "regular" 2019 BMW M8 Coupe taken from an official BMW teaser video of the 2019 BMW M8 coupe. Compare this wheel design to the one in the second pic below taken from Klier's spy shots of the real 2019 BMW M8 competition coupe. Personally, I don't care too much for the wheels on the M8 competition...they appear too busy. I definitely prefer this regular M8 wheel design. What do you guys think?

Here's the teaser video:

Save for the M5 Comp wheels, I haven't been feeling the wheel designs for the M cars as of late.

Speaking of the M8, will it be lighter than the M850i, and if so, by how much? Looking at the weight data of the M550i and the M5, the latter is around 60 kg / 130 lb lighter than the former even though the M5 is supposed to be beefed up in several areas. Is it possible that the M-AWD system is a lighter package compared to the one in the lesser BMW's?

I don't know where you're getting your data from, but the M5 is HEAVIER than the M550i xDrive.

The M550i xDrive = 1,885kg according the EU1 standard.

The M5 = 1,940kg according to EU1 standard.


However, it becomes a bit unclear when you look at the U.S. specs, where the M550i xDrive and the M5 are pretty much identical in curb weight.

Both systems add around 65 kg. I expect the same weight difference like the M5 and the M550i minus the weight of the difference between steel and CF roof (the weight of the tested M850is has been with the CF roof). So something like 54-55 kg

Thank you for your reply @Betty Swollocks

The data that I mentioned were from Auto Bild and Sport Auto magazines that were provided by @DeDe and other members, in addition to Car and Driver Magazine, where the data are as follows:

Auto Bild:
M5: 1890 KG
M550i: 1950 KG

Sport Auto:
M5: 1907
M550i: 1967 KG

Car and Driver:
M5: 4288 lb
M550i: 4412 lb

I think that I should've included that in my previous post. Unfortunately, I neither speak nor read German, so I don't know if there is any explanation regarding the weight.

The information you provided is the official weight data from BMW, I assume. It's more convenient for the M5 to be heavier than the M550i, but the data above got me to ask my original question.

Both systems add around 65 kg. I expect the same weight difference like the M5 and the M550i minus the weight of the difference between steel and CF roof (the weight of the tested M850is has been with the CF roof). So something like 54-55 kg

Thanks for the weight info The 8 series has the Carbon Core, but I'm not sure if there is any effective weight saving. BMW may have some weight saving techniques for their ///M cars, after all.

I'm not a customer, so what matters to me is the information that I will read when the car will be road-tested
