The same DSG trans is used in the S6 TT V8.
When tuned, 6xx ft lbs holds just fine.
That being said, the whole DSG advantage has shrunken to nothing. The ZF 8 speed holds more power and will be more reliable long term. Less costly to buy, service and own.
The new GM & Ford 10 speed auto is faster than Porsche's PDK.
Amazing what happens over time.
