Its hard to compare new and old M3 , because new M3 is bigger, got bigger engine (4200 ccm V8 is heavier than 3400 ccm R6)... E46 M3 and E92 335i is better comparison... But important is that new M3 is faster and better to drive than old one, despite higher weight.




WRONG !!!
The old engine displacement was 3.215 ccm; inline 6 and it is heavier than the new 4.0 V8 that has a displacement of 3.998 ccm.
