G8X to F8X, differences are 50whp + slightly better tire (only bigger in width) and a 300lbs heavier chassis. The AWD doesn't necessarily improve track time because of weight and imbalance, even 9114s cannot squeeze a better than over the 2s..

I tend to believe G8X is smaller performance improvement over F8X than F8X over E9X. And thus 7:4X would be a legit estimate.

2) As mentioned, M5 is positioned at 7:36 and BMW would want a clear hierarchy as always.

3) if base/comp clocks at 7:3X, M34 CS needs to be in the 7:20 which is ridiculous. That's Audi R8 performance territory, a lighter, stronger ground up supercar and is what 992s is incapable of. Traditionally 991 base or S is equally fast or even faster than the ultimate M car (csl/gts).

IMO, G8X would be a serious dragster like M never was before. But track performance improvement should be incremental like the evolution thru every generation.
Good analysis, though remember there is no talk or rumours of a CS but there is about a 600 hp CSL. I believe that’s going to be an absolute track monster with a time below 7:20...

Also your F8X vs G8X analysis is missing some facts, the G8X track package comes with Cup tires that are 20mm wider on 1.5” wider front track than F82 and the F82 7:52 time is set with 425 hp so the gap is 80 hp to the G82 comp.
