No doubt the M340i is a sweet car but it is in no way comparable to an F8 ( i mean in some ways yes, but no) .. sure there are some similarities, its still a BMW after all... but it just does not have the DNA that M cars have is what I'm saying.... not to mention that hideous grille =/
Dont take my word for it, take it from a BMW engineer...
also this is a good one
For reference would love to hear him talk about the new M340i
