Lets not forget this little gem I posted awhile back... its looking to be right on the money so far!
332kw = 452 PS
While this engine should have ended up in the 1M... it looks like it is destined for the new M3. I have heard from three sources so far that the next M3 will be based on the N55 and called the
S55. It will have vanous head and forged camshaft/crankshaft and pistons and rods. I hear the power output will be in the 440 PS range. It also might have some pretty cool CF use of part slike a CF driveshaft. I also hear the DCT is all new with "more gears" than currently employed. I guess in time we shall see whats what.
