BMW M5's Project Leader Says V8 has Few Things in Common with X5M and X6M Engine

Like its predecessors, the new 2013 BMW M5, which received its public debut at the 64th Frankfurt Motor Show, is based on the regular 5-Series sedan with some subtle exterior modifications but a whole lot of changes under the skin.
Now, some may think that BMW's M Gmbh performance division simply took a 5-Series sedan, beefed it up a bit and shoehorned the twin-turbo V8 found in the X5 M and X6 M SUVs under it's hood. However, Maximillian Ahme, the man that led the M5's development team, says that's not the case.
In an interview with the BMW M magazine, Ahme shed some light on the development and the unique features of the latest M5 super saloon.
