My apologies for missing that.
I think swamp's second guess of 3600lbs and 450hp for the F80 is a very good one. I realize that is more than a 4% improvement vs. the current car's 8.81 lb/hp (though that figure is for the E92, not the E90 which is slightly heavier), but irrespective of that, it gives the F10 M5 with 7.66 lb/hp about the right amount of breathing room IMHO.
