Not that it matters because either transmission will be fine with whatever tune you throw at the m2.

BMW went with the ZF Auto in the M5 because it's faster than the DCT.
The Getrag 7DCI700 used in the M2/M2C/M3/4/5/6 is rated at 700N-m (516lb-ft) crank torque.
DCT can handle some serious HP & Torque.

F90 M5 makes 553lb-ft in its stock form which is already higher than what the DCT is rated at. The main reason BMW chose ZF8 over DCT on F90 is because of the torque limitation of the DCT not ZF8 being faster. |
Probably both. That faster 0-60 is a carrot to some buyers. The ones that solely think 0-60 is the bar to measure a car.
