The S65 has a higher specific output than the outgoing naturally aspirated Maserati V8. There's really no reason to doubt that the upcoming "S55" will continue this trend vs. the new V6. This all makes sense of course, when you consider that the M3/M4 are performance cars while the Quattroporte is an executive sedan.
I think the M3 will be around 140-150 hp per liter.

Just look at the 911 GT2 RS, makes over 172 hp per liter and you know Porsche could have easily pushed beyond that even. Granted, Porsche makes prob the best turbo engines in the world but regardless there is surely a good amount of power to be had beyond the Maserati output.
