With all these rumours I do not care whether V6 or I6. For me what is important is that the M3 get a special M worthy engine, and not just a tuned BMW AG engine. I also do not care about M3 Legend any more, let the F32M just be an M version of the 4 Series Coupé F32, and so be called
M4. I'll take an M4 CSL.
