You are exactly saying "more mass in the rear is better" but this BMW has less mass in the back. Again; 53 Front (more mass in the front). I think you need to comprehend what you are really saying...

Not sure whether I'm following you. 50/50 isn't ideal cos it's better to have more mass at the rear up to a limit. 50/50 though not ideal is still better than 53 front 47 rear. Where's the contradiction?

His logic is;
1 - 50/50 is not great as BMW wants us to believe,
2 - Rear bias is better

G80/82
1 - Has no 50/50
2 - Has no rear bias either.

So, G80/G82 is even worse than a 50/50 car, yet he is arguing with the people who are not fond of this weight distribution ??? What is the point?

Somewhere along you’ve misunderstood. CanAutM3 is leading the pack that is critical of the G8X technical characteristics and the added weight on the front axle and change in rear-front distribution is on of his main area of criticism.

I.e. he is agreeing with you. Heck he is even jumping ship to one of car worlds most rear weight biased cars a lot based on that specific change...

Yes, that's it: more mass to the rear is better; BMW moving in the wrong direction.

What's so hard to comprehend : ?

Not arguing, but bringing additional insight that even 50/50 is not "ideal" as BMW have claimed for so long.

Too much variability here for me to attempt any speculation. We'll have to wait for the official weight specs

From the video:
F82 Comp DCT on 20", likely fully loaded; 1,640 kg
G82 RWD 6MT, 19/20", CF seats, full leather; 1,674 kg
Full tank, which means ca. 59 litres for both vehicles.
According to the data from the press release, a base German-spec 6MT G82 M4 weighs 1,700 kg (DIN, i.e. all fluids, 90% tank). Such car has basic LEDs, HiFi audio, memory seats, 18/19" rims, acoustic glass
Base 2018+ 6MT F82 is 1,570 kg; DCT-equipped is 1,595 kg (DIN). Such car had adaptive LEDs, HiFi audio, electric cloth seats, 18" rims, no DDC, no CF driveshaft.
My maths sucks, but if we compare apples to apples and calculate a DIN weight with empty fuel tank, then their F82 in the video would be approx. 1,596 kg and the G82 1,630 kg.
Base F82 6MT 1,530 kg; F82 DCT 1,555 kg
Base G82 6MT 1,660 kg; G82 Comp 1,685 kg, again all DIN w/o fuel.
Add ca. 10 kg for the standard seats and you're at 1,64x kg. None of the G82 numbers add up. How is this optioned-out car lighter than a supposedly stripper model used for certification... Can't trust them manufacturers with these figures.
Also, I'd like to find out the weight difference between the Getrag M-DCT and ZF 8HP. And no Al fenders on the new car?
All in all, though, a lightweight 6MT G82 is still heavier than a loaded DCT F82.

DIN weight, as I eluded in my previous post, features a car in running order with 90% fuel and no optional equipment; EU/EG-Leergewicht weight adds 75 kg to that number. That means there is no need to add 10 kg (standard seats) to the 1,660-kg "base" M4. If 1,630 kg is what an M4 weighs with buckets, then you just add ca. 10 kg to that figure and you've got a car with standard seats. I did not see CCBs in the video, it is possible it had them; no argument here.
BMW Deutschland use EG-Leergewicht in their brochures. Standard equipment varied a lot on the F8x M3/4 which is why I highlighted some of the standard German features. Some markets got manual seats, base iDrive without sat nav, etc.
However, it is safe to say that BMW high-key pulled a Ferrari on us with the original weight figures of the F8x. Somehow the DCT lost weight over the years, too.
03/2014 (all DIN, 6MT/DCT)
F80: 1,520/1,560 kg
F82: 1,497/1,537 kg
01/2015 (Competition Package)
F80: 1,535/1,560 kg
F82: 1,515/1,540 kg
09/2018 (OPF, no CF driveshaft, non-Competition)
F80: dead
F82: 1,570/1,595 kg
Head hurts from these numbers, am out.

'Claim to fame' or 'claim to shame' ? Maybe some soul-searching might inspire BMW M to do a humble reset 'back to basics':

You'll have to wait for the new m2 for a true lightweight option and a shorter nimble wheelbase.
Exactly what I'm doing. The G87 M2 is my potential F80 replacement

As others have said, we don't really know much until the cars are available to be weighed and driven. That said, I would be shocked if the G80 does not deliver better track times than F80...that would be almost suicidal on BMWs part. Those who measure success in 0 to 60 (AWD!) and Nürburgring times will be largely satisfied; those who don't want a bigger and heavier car....not so much.

He has been so critical of bmw lately and especially the G8x. When bmw release a video proving him wrong his response is attacking them while using an innocent bmw employee as his smoke screen to discredit the video.

His comments on Klaus was just cringeworthy and bullying.

When someone called him out in the comments he replied in typical bully fashion saying the guy was on a tangent and didn't comprehend...
Man, I dunno. I dont see what you point out at all.

On Cringeworthy - that is BMW latest ads on 7 series vs IX.

Bullying is calling its customer boomers.

US twitter account is run by a tone deaf guy-gal, and yet Robert went out and said that simply those guys at the top are responsible.

None of what you pointed out - bullying of Klaus, cringe etc is in that video. Of course the dude is confident in saying what he thinks. Since when is that a bad thing? Since bunch of idiots stormed the capital, and now god forbid anyone has an opinion? Come on.
