But what about the new 335i. It is a much better comparison. I've seen a lot of ambiguous figures on both even in the BMW press release that issue was noted and discussed here on the forum.

Pretty much agree here both on method and results

I'd pretty well guarantee that won't happen. The primary chassis of the base car is already set in stone. It is steel and thus the M3 will be the same using the same basic chassis.
