If M-GmbH technicans says the new developed V6 was in all points better than the I6 based on the N55 ... I beleave them. And only on an V6 you can use the "best responding turbo system" of the world this one of the S63Tü - with minimal lag ... it don´t works on an inline engine. And if you look at the GT-R you could easily see what an improofment the change from an I6 BiTurbo to an V6 BiTurbo could be !!! Only one of many reasons to choose an V6 over an I6 in an sportscar.

I am not with you, all M3's since E30 used the base engine from an existing parts bin, and were developed into a special M3 engine. This hasn't changed for F80/2.
Sure E92 had a more special engine, but that was helped by the fact that the M3 GTR had a tuned version of this engine for racing, and it existed in V10 format already. Easy to lop off 2 cylinders. If the S65 didn't have such a short stroke (poor for turbocharging) they could again lop off another 2 cylinders to make V6 Turbo.
As for more options turbo charging a V engine, that is rubbish, an inline engine is much easier to plumb.
