I don't get it, the M135i with a great I6, and the new 1M with a supposedly 4 banger?
Strange...
I know the E30 history is like this, and the M2 is something like the 2002tii once was, but coming from E87 1M with N55, and the F20 135iM inline 6, it seems to be a step back using a 4 banger in the new 1M/M2...
