Rumor is that a strengthened version of this 8-speed automatic will be the replacement of M-DCT/SMG in the next M5 with the X6 M and X5 M engine was as well. With all the issues in M-DCT and SMGs, BMW is going back to auto slushboxes for M cars. Besides, M-DCT is not strong enough to handle the low end torque anyways.
For a torquey low-revving engine lock-up torque converted automatic make much more sense than dual-clutch automatic transmission.
""A great sounding, responsive, high-revving, naturally aspirated engine is part of the DNA of a thoroughbred sports car. No two ways about it."
