My BMW M driving course friend (was just over seas at BMW M) said BMW M were already looking to SMG 4 for all future M cars which will have this amazing sort of dual capability.. they want a dual-clutch system for the drive modes and manual modes 1-5 (for super smooth shiths) then for S6 the clutch will be totally disenaged "ala Formula 1 gearboxes"..
So when you press S6.. and gas it hard and change up the computer will synchronise everything in miliseconds and drop the revs just quick enough for the gearbox to slot into the next gear.. So its going to be brutally fast shifting.. just like the F1 cars who only use their clutch to pull off.. no clutch for shifting..
They already have the designs and are progressing towards a protoype..
