S6 traps 1/4 mile in low 12s @ 118mph
That's in M5 teritory
I dont see how 550i will be able to come even close to these numbers
Re HP: I think its highly underrated.
S6 does not feel like 400Hp car at all, more like high 400s. It's also a lot faster than my X6M
DCT is big help here too, it's lightning fast
P.S. Turbo lag on S6 is a lot less noticible btw
