This isn't a new practice at all for BMW, so don't think that I am implying it is inferior. BMW used two 3.0-liter inline-6 engines for its 6.0-liter V12, and the 4.0-liter V8 in the M3 is a chopped version of the 5.0-liter V10 in the M5. I simply don't know if the balance dynamics are the same for an inline-4 as they are for an inline-6.
