The E92 M3 pretty clearly decimates the E46 M3. I don't trust any results showing otherwise for any contest as "apples to apples". Have a look at these CarTest sims. As you can see most results are right on the money with known/accepted best times (or within a couple of tenths or mph here or there). 0-150 has the E92 ahead by 20 car lengths (not shown below but calculated by CarTest) and nearly 8 seconds. And no the margin between the F82 and E92 will certainly not be as large as the margin between the E46 and E92. It just takes "exponentially" more power to squeak out the same sized performance gains. Thus the M4 will still in my proper view of the word decimate the E92 M3, but certainly by less than that between the prior generation.
