Best regards, south
Look at the S5 vs RS4 engine weights, here you see a difference of 20Kgs, so it's perfectly possible for two seemly identical engines to weigh differently.
Only a suggestion.
What does any of this back and forth debate got to do with the next M3 engine????????????????????
Serious guys, all the engines in this endless debate are brilliant, BMW have chose small capacity N/A, Mercedes have large capacity, some chose turbos, others chose superchargers, etc, etc, etc.
It's not what under the hood but the results that count, always remember that.
