DCt-Drivelogic-DKG question

motex2010-08-30 01:20:26 +0000 #1
Sorry for such a stupid question, but Im confused if DCT is the same as Drivelogic or the same as DKG ?

Can someone explain me how many transmission systems the E92 offers?

Thanks

Drivelogic refers to the settings for manual of automatic mode on the DCT. S mode (manual) has 6 modes. S2, for example, has a very soft/smooth upshift but no rev matching on downshifts. S4, for example, shifts much harder and rev matches downshifts. (Note--the settings don't seem to matter in terms of actual 0-60 times or other measures of acceleration.) Same idea in auto mode, but auto has only 5 modes.

DKG is just VW's term for the DCT; just as PDK is the Porsche term for it. There are differences in design and software function, but the transmission concept is essentially the same.

Thanks for your feedback !

So the real BMW name for the double clutch transmission is DCT right ?

I know pretty well how this transmissions work because Im a former E46 SMGII M3 owner, so I understand about downshifting on the S modes and all other modes this trans comes with.

DCT is just the English translation of DKG, which stands for DoppelKupplungsGetriebe, which literally means Double-Clutch Transmission in German. It's just a generic name for this type of transmission, and it's used by Getrag as well as ZF.

The Porsche version of DCT is called PDK (Porsche DoppelKupplungsGetriebe).

The VW-Audi group version of DCT is called DSG, which stands for Direct-Shift Gearbox or Direkt-Schalt-Getriebe.

vw/audi initially called their dual clutch dsg. They have now changed the name to s-tronic.
