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 understand your point, but the modified 3.2 engines in the 3 previous I6s (M3 evo, E46 M3 and CSL) were great. While this new engine may not be bored out to a unique displacement, it will be heavily modified from a regular-series BMW just like M engines of the past.
I'd have preferred the GTS 4.4 allied to lower weight and some mpg improvements but I still have faith the S55 will be a very good and well suited engine. Remember, this car is only likely to be 100 lbs lighter so torque is going to be welcome (even though I do not find the current 4.0 lacking due to its perfect gearing)
