The problem is that BMW has drank it own kool aid on a 50-50 weight distribution. Even if another engine design could improve it more toward a rear bias BMW would probably purposefully push it back to 50-50.
The problem with a turbo charged M3 is mainly the visceral race car like scream of a very finely tuned engine at 8000+ rpm with a totally linear power curve all the way up. Performance wise the new car will win for sure. Nonetheless we can not down play the significance of the emotional aspects of a Ferrari type engine experience.
