Case in point, some BMW official numbers:
The MT E46 M3 0 to 60 4.8 sec and the MT E92 M3 was 4.8 sec.
N54 grossly underrated, the S65 not the case.
Going by BMW official numbers, an E46 M3 will smoke a N54 335i to 60mph...not the case in the real world.
From insideline.
Real world numbers will give you a better sense of what kind of improvement we'll see.

You are confusing 0-60mph and 0-100km/h. E46 was listed at 5.0s to 100km/h and 4.8s to 60mph. E9X 6MT is 4.8s to 100km/h and 4.7 to 60mph.
BMW numbers are usually very conservative. Meaning that they are easily achievable in the real world. I also believe they don't exclude the traditional 1 foot roll-out. And yes, on average, a E46 M3 is usually slightly quicker to 60mph than a 335i.
Swamp2 did very good predictive analysis on the 0-60 performance of the F8X showing it will be significantly quicker than the E9X.
The fact that BMW officially quote the F8X half a second faster than the E9X indicates that they are confident it will be quicker by a significant margin to 100km/h / 60mph. That was my original point
Will it be 0.5s faster in the real world? I agree, we will have to wait for instrumented tests to see...
