The cross plane crankshaft in a M3 V8 makes it sound weird sometimes, I prefer an inline 6(E46 M3, N52) for that matter, and having had such a M3 V8 for two years.
Not that spectacular imo, sometimes a Nascar when cold, nice, sometimes just boring(just like Nascar) and annoying imo.
The //M V8 should have been a flat plane crankshaft design , like the Ferrari V8s.
No not a big fan of the M V8 here, by experience....
You want a nice sounding competitor? C 63 AMG engine sounds ten times better than the M3 V8 imho.
