That's easy: Build a 1970s Italian supercar-style chassis -- heck, get some consulting help from Lamborghini, if you need -- but then, in stead of a V12 or even a V8, put one of your trusty Bavarian straight-sixes in the middle of it.
What, you mean someone else is trying to usurp the venerated "M1" moniker?!? Infidels!
