Yeah, I agree, I will be interested in seeing how much torque / HP they apply to the C8 Corvette's (undoubtedly wet) concentric clutches in its DCT. It was a recent BMW executive (or a Design Lead Executive) who said that in the future, torque capacity limitations would cause BMW to migrate totally away from DCT transmissions... to conventional torque converter based automatics... which per this fellow - are increasingly close to being equal to a DCT for (general) shifting speed. I say general, because a dual clutch transmission can sometimes be fooled into going into the wrong gear or in the wrong shift-direction... and then it fumbles about (a little). Porsche's ZF based PDK 'box has, to date, the most-advanced programming to make this a rare occasion (apparently).
One thing I should like to mention, here (and some of Y'All may roll your eyes... "Here he goes again..." - sorry) - is that dual clutch transmissions do NOT double-clutch (actually, like the Magnetti-Marelli hardware/software driven single-clutch automated manuals sometimes can - Ferrari F1, Maserati CambioCorsa and DuoSelect, and the BMW SMG boxes). What I mean, here, is these single-clutch automated manuals go into neutral (with clutch engaged) and rev the countershaft to the correct speed so they actually are (under those somewhat rare occasions) easy on the synchromesh. I say rare, 'cuz on the DuoSelect... when you command it to downshift (when the engine rpm is greater than 5000 rpm - crazy, that! - it will actually double-clutch down to save the synchro's. Re DCT's.... what this means when upshifting... is that, so what that they don't double-clutch up... Even though the shifts are lightening-fast {when swapping from even to odd gears (or vice-versa)}... actually, internally, when going up - the non-engaged gearset can lazily engage a gear... 'cuz it is, in fact, not needed yet. Easy-Peasy. But going down.... when in manual mode... and you have a "downshift artist" flipping paddles down at high speed 'cause he / she loves to hear that rev-matching / engine note... well, the non-double-clutching internal-shifting of the DCT box is down-right BRUTAL by way of speed and positive action. Now DCT boxes have double and even triple cone synchronizers.... But still,as time goes on, the synchro's do get knackered. That is why I do not like DCT's.
Having said all of the above, so far, empirical results with DCT's have not been that bad in terms of synchro life.
Time will tell, I suppose, ultimately how good and long-lived DCT's prove to be. We are getting to the high mileage realm of knowing pretty darned soon.
