Either way, this engine would, in my opinion, be a better fit within BMW's current product strategies than either an S65Tu or any V6.

Nice idea ... very nice indeed. Best solution for the rpm/Redline issue ... an high reving Turbo engine = best turbo solution for the M3/M4 but costly.

I donīt think that an I6 based on the N55, re-inforced, with an bigger turbosystem/more turbo and the needed pipes could be lighter then an N54 ever a little bit heavier ... I think it would would weight somewhat between 195 and 200kg
