The E46 M3 makes a lot of power per liter but in general modern engines make more power because of Higher revving (7000 not 5500rpm), variable valve timing, knock sensors that allow ignition timing to be right where it needs at all rpm and load to be without a power killing always-on safety factor, and direct injection.
