I know we can nitpick and lament a lot that we are hearing but these videos just keep reminding me how much I love this product (the M3 and M4). It is crystal clear that they care about it (and our experience of it) so much despite also having to work within certain business constraints.

Here are the two side by side with Riviera in the foreground and Mexico Blue in the back.

You asked for a BMW color, and they suggested a Porsche color?

Is the rear subframe still connected without bushings to the chassis?
Under the hood bracing looks fussy compared to previous gen, how much % improvement in stiffness we're talking?

+1

I think that was one of the better videos. It shows that good effort was made to stiffen the G8X chassis so that suspension tuning can be optimized.

As far as chassis stiffening, I don't see it as a meaningful upgrade compared to the F8X though. When they specify that they improved something, it is not clearly stated over which baseline. I interpret that it is over the base G2X series and not necessarily over the F8X. However, if the G2X chassis is stiffer than the F3X chassis, they do have a better starting point.

The picture below illustrates the F8X stiffening elements. From what I observe, the F8X has re-enforcing between the strut tower and A-pillars at the top of the structure, which the G8X does not seem to have. It could be the reason they added structural elements that connect the front subframe with the side frame rail at the bottom of the structure on the G8X (that the F8X does not have). They also mention that the steel was the best material for the front structure due to the limited space (not enough room for a CF structure), so I doubt we will see a lightweight structure even on a CS or CSL version unless the under-hood area is significantly revamped.

They do specify that the rear subframe is rigidly mounted to the uni-body of the G8X, just like on the F8X, which is a good thing. As depicted below, the F8X also has connecting elements between the rear subframe and the side frame rails.

As for the suspension, it looks like an evolution of was found on the F8X. The F8X also had bespoke elements made of aluminum.

They REALLY need to do these in landscape instead of portrait. I know the theory is that people are watching on their phone, but I'd much rather turn my phone sideways to see more

The head of driving dynamics development appears to be driving on a closed course at 10 and 2. Uh huh.

I wish they would of done something different for the springs/shocks (bilstein damptonic?) and a next gen edc system (like PASM from porsche). And why not ride height adjustment from the factory? (maybe on the competition model)

at the price they're asking there's no reason why they shouldn't evolve the springs/shocks combo.

As far as I know both the F80 M3's M Adaptive and Porsche PASM (991 generation) have always been Bilstein Damptronic. 992 is using Bilstein DTX which is the latest version and I'm hoping G80 also uses DTX because it feels sublime on the 992s I've driven.

His "Driver's Ed" instructor was sitting shotgun.

Yes!!! I couldn't f***ing believe it. I ended up getting approved for Fire Orange but my build was showing a March 10 tentative build date and now it's not showing ANY date so.....going to be a long wait.

I agree with you. Extensive use of aluminum decreases weight I guess.
It may be too stiff for daily use. If its anything like the current X3M competition then expect a stiff punishing ride, even on comfort mode.

There's no such thing as having too much chassis stiffening for a daily driver until it starts intruding on cabin and trunk space. See below too.

Chassis stiffening makes ride SMOOTHER, not stiffer, just FYI.

Really happy to see all that stiffening. I'll take a heavier, stiffer car any day, that is weight well utilized

I interpret it as an upgrade over the f8x. You tend to be more of a "glass half empty" kinda guy lol.

We can all be sure the G8X will be stiffer than the F8X. Absolutely zero doubt.

[danniexi]

all this mentioning of “stiffening” and now im nursing a semi.

I always thought BMW used a system from Sachs (since the e9x generation).

Funny. I tend to use objective technical observations to form an opinion, not emotions. So half full or half empty, to me there is still the same amount in the glass...

Agreed. Most likely because the base G2x chassis is stiffer than the base F3X chassis and not necessarily because there is more/better bracing in the G8X. Just the fact that the G2X is larger than the F3X makes it stiffer in bending and torsion.

This settles the debate at least.

15% Hmmm...

Interestingly, IIRC, the G20 was quoted to be 25% stiffer than the F30...

well then I guess the stiffness difference between F30 and F80 is > than the difference between G20 and G80 ?

Don't know the differences tbh...

[SYT_Shadow]

In the end it's pretty irrelevant if the difference between one generation's regular 3 series to the M3's rigidity gap is larger or smaller. What matters the most when comparing dynamics between two M3 generations is how rigid they are vs each other.

The G8X M3 is, as expected, significantly more rigid than the F8X generation. I mean seriously people, the hate is strong with the people who doubt this was an evident conclusion.
