But perhaps the X3 M mules are simply better disguised or just too nondescript to have drawn much interest or attention.
I still find the whole idea of an X3M odd. I get placing a monster engine into an X5M in order to compete with the Cayenne Turbo and the ML63, but is there really a market for high performance mid-size SUVs? Stuffing the next-generation F8X engine into an X4M makes more sense, since that's a sportier form factor that will compete with the likes of the Macan and Q5RS (or whatever Audi decides to call the top performing version of the Q5). Of course, from a timing perspective, there's no way that the X4 (let alone the X4M) would beat the F80 to market.
