I seriously wish the S85 wasn't ending its production life.... it is such an amazing engine, and they could have ringed so much more out of it. But they want that economy, and want to keep it dialed back for reliability. What better way to do that than with turbo's.
I just pulled the exhaust off a 2010 M5 today, and the sound that thing makes when its not sonically reigned in... good lord, the only way to describe it is track side during initial starts! SPECTACULAR!!
