The M3/4 was never this close to Carrera S!

You would need to compare the 991.1 to the F8X, which was the relevant 911 chassis when the F8X was released. The 991.2 was released 3 years after the F8X launch. In the same way, the 992.2 will coming out in a couple of years.

In my opinion the G8X had much, much harder task to catch up with the F82 GTS, because the F82 GTS has set the bar much higher compared to E92 GTS!

On street tires:
E92: 1:41
--> 3 sec
F82C: 1:36
--> 2 sec
G82C: 1:34
We're comparing only one data point here, so it means what is means, but I see this just as a normal generational leap. Nothing extra-ordinary. A big portion of the leap from one generation to the next is attributable to tire tech. We can't even directly compare the F8X and G8X with PSC2 as Michelin have made significant improvements with the latest gen PSC2.

According to BMW, the base G2X chassis is 25% stiffer than the base F3X chassis while the G8X is 15% stiffer than the F8X. Do the math... |
What is more interesting than absolute chassis stiffness is which areas they have focused on. We have discussed this before...
As mentioned in my previous post, the underbody bracing on the G8x is larger and has more solid anchorage to the chassis. This helps control especially the front crossmember. Meaning less movement in front suspension anchorage points.
This is also a point made by BMW.
