DSG - have I missed something major?!

[clip]

Just talking today to someone, and discussing Tig's, GTi's and R's. Can someone please clarify the situation with the DSG boxes for me?

I was under the impression (wrongly it seems), that the new 7 speed DSG is the duck's guts. However, I've now been told that the 7 speed (as in the new Tigs) is a dry clutch (as opposed to the wet 6 speed in GTI's), and that it has lower specs than the 6sp (especially torque limits). Which is why the 7 speed is in the lower powered VW's while the 6 speed wet is being retained for the higher performance spec VW's and Audi's. Can someone please clarify for me?

Just quickly from the top of my head there is two versions of 7 speed DSG. As used in the new Polo max rating 250nm Torque and the other used in Tiguan/Q5 and Transporter with AWD Twin Turbo setup rated to about 550nm. Anybody else confirm?

Two 7sp DSG's then? But isn't MK6 GTI, R using 6 speed wet clutch? That would make 3 DSG in current model VAG mix.

Yeah...

The "Original" DSG was the 6sp wet clutch DSG. VAG rate it for 350Nm and it has FWD and AWD versions.
Later came the 7sp dry clutch DSG. VAG rate it for 250Nm and it was designed to greatly reduce maintenance cost, weight etc.
Then came the 7sp wet clutch DSG from Audi. VAG rate it for 550Nm and thus far I've only seen it in AWD applications. It's a monster of a gearbox though, having about twice the oil of the original 6sp DSG and weighing over 140kg!

thanks corey, so current MK6 GTI has old 6sp wet clutch DSG, Tig has 7 speed wet clutch monster?

Yes.

I think that it'll be interesting to see what happens with the 6sp DSG, whether it continues as is or is replaced by a new version, maybe with 7sp as well. I don't believe that the 7sp 550Nm will "replace" the 6sp any time soon as it's just too large and too heavy for the "smaller" cars (and by that I mean including the Golf).
