Porsche.
The "narrative" about not being able to handle the power is just that...BMW's narrative. Of course you can design a DCT type transmission properly that will handle massive torque...Porsche has long ago done that, and hammering it through AWD now up to 580hp and 553 ft-lbs before the owners start modifying them, lol.
Road and Track tested that supposition by doing a 50 year celebration of Porsche in 2014 with a 911 Turbo S with PDK by doing 50 launch control starts
*in a row*; they lost count, actually did 61. No issues, no overheating, no limp mode, and all runs within a few tenths of each other...snapping off 0-60mph times in the mid-2s in the process.

That's what Porsche chief propeller-head Wolfgang Hatz said when someone asked him how many violent, Bugatti-quick launches the 911 Turbo S can perform before grenading itself.
"You have to have very intelligent cooling for the clutches," explained Hatz, "and choose the right material." The 911's clutches are bathed in oil, which is cooled, as are all the car's powertrain fluids. Hatz added that those Porsche-designed and ZF-built clutches are considered lifetime parts, good for well over 100,000 miles.

To any competent engineer, Wolfgang Hartz's comment is of course a "duh" response. He's simply stating the obvious and of course knows that.
BMW has never even designed *any* DCT type transmission with an objective like Porsche's. Beancounters run the show at BMW and would never allow them to actually design it as in the TurboS above, M-car or not. Hence the propaganda mission is started since the goal is financialization, and consolidating the entire product high end line behind the same torque converter automatic transmission is the goal. Leave it to the high-dollar paid
spindoctors in the BMW marketing group to figure out "technical reasons" to make it sound legit and watch the masses buy the spin.
