Just for the record and no intention to take the discussion somewhere unnecessary.
Mean the 'ring times. Both 8:15. I am sure the 1 series M is faster, it should be given it is 6 years newer, only weighs ~150lbs more and has more torque, HP, better tires etc. Stock acceleration is about the same too... however the N54 / 55 are much more tunable.
