Having driven my 2014 M5 w/Comp Package (and CCB) long enough to get through the break-in period, I think that BMW has (under)rated the car at 560/575 HP to simply give themselves room to bring out the 2018 G version with an (under)rated 600 HP, less weight etc. Having owned and driven the E60 for about four years, it is absolutely clear now that the F10 is far more powerful (and better in virtually every way)...but that BMW needed to give themselves room with the G version . This equates to modestly higher rated HP/~15-20% weight savings on the G version, optional AWD and yet another killer M5. That's my theory on why BMW has underrated this car the way it has. Thoughts folks?
