There is no wet DCT developed for Ford from GETRAG...
And ST is a niche car (not so many sold vs std focus), would be too costly to develop a DCT only for this car hence no DCT option

!
Yes... luxury automatic / semi-auto sports car are selling.... but the ST is another thing (economic bang for buck sporty compact car)
My point is that you're trying to eliminate all possibilities without thought, knowledge, or reason. The ST isn't manual specifically because it's a niche car-it's a manual because that's what Ford decided. It has nothing to do with 'bang for buck' because all they would do is tack on the additional cost for the option-just like every other automatic vehicle everywhere.
There are transmissions that could be used if the electronic side was figured out.
Screw listed torque numbers supplied by the manufacturers, cars with various transmissions have been pushing past those limits for years. Until anyone tries to push a dct to its limit we'll never know the actual real world limit of it. I'm pretty sure the clutch is the biggest limiting factor there, maybe the actuators too. It would be nice to see upgrades for those as time goes on since dct technology keeps getting more widespread.
Exactly this. Parts are almost always underrated, but no one ever knows by how much until the limits get pushed. In order for companies to justify making aftermarket parts there either has to be a forecasted need or a demand, and unfortunately there just isn't either one in the Mk3 community. This platform has been available for sale since late 2011 and I have yet to see one single vehicle find out what the true limitations are for the DCT in regards to power.
I enjoy having a manual for daily driving, but after getting my DCT tuned I can honestly say that I would rather have had that for performance driving. Whether it would hold up or not is completely irrelevant at this point, because it hasn't been done/tested.
