From (curb weights):

07 M3 Coupe - 1611kg
08 M3 Sedan - 1664kg
06 RS4 - 1736kg
07 RS4 - 1728kg

So the RS4 is conservatively ~110kg heavier than the M3 Coupe in reality...

110kg is considerably more of a difference. I still think the lighter RS5 with MLP and more power will be a great match for the M3. It's just depending on how much lighter/balanced the RS5 will be and what engine they decide to use.
