7 sp DSG 400Nm?

[cme2c]

Just noticed the European release of the new transporter. Top of the range has a twin turbo 2l common rail diesel. It is claimed to have 132kW /400Nm and run a 7 speed DSG. Hmmmmm.

It will likely be the Audi S-Tronic 7 speeder, published torque up to 550nm.

Not the baby one seen in the cars.

Thanks, Gerhard. That makes some sense. But using an Audi box in a truck but not a 103TDI or GTI ? I sometimes wonder.

[phaeton]

Cost.......

Cost.......

Ah yes. I just looked at the Euro prices for the commercials. I suppose its different competing against Vitos than corollas(in Europe)

I think that the Audi S-tronics box is too long to fit transversally. They would have to change engine/box arrangements to fit it.

I read today something along the lines of "VW has had to beef up their DSG box to suit" http://www.carsales.com.au/reviews/2...neration-16785

So I looks as though there is plenty of potential in the 7 speeder with dry clutches.

Would that mean the dry 7 speeder will eventually replace the 6 speed oiler across the entire range where the donk is a high torque one?

They are using it in the S3 http://www.egmcartech.com/2008/09/30...d-twin-clutch/

Errm, No .... S3 uses a 6speed DSG (S-Tronic) That article is incorrect. (it is also a year old) Have a look at the specs on Audi's websites ....

7Spd DSG (as in Q5) is for a longitidunal engine not for transverse. T5/T6 & Amarok will get the 7Spd.

VAG does not have a 7spd DSG for the transverse engines rated above 250NM. 7Spd DSG for longitidunal engines only rated @ 550NM.

It is a totally different gearbox. It will not fit in a FWD car such as a Golf etc.

Which brings me back to my original point. What 7 speed DSG is VAG going to use in the transverse engined transporter and could it be grafted to the Golf etc?

Haha, which brings me back to my last post -

That would be a good thing. OTOH, is the "beefing up" real or have they not changed anything except the spec sheet, crossing out 250Nm maximum and substituting 400? APR seems to have no problem putting 300+ Nm through the 7 speed dry clutch DSG with their 151kW 1.4 twincharger reprogram. This is relevant to me as a 118TSI DSG is off the boat and (slowly) heading in my direction. Also, the reduction in complexity and servicing costs with the dry clutches vs wet would annoy me if I had bought a 103TDI.

You could be right there, VW quotes a spec which in the case of both the 6 and 7 speeders is way below the danger level.

The "beefing up" is probably only to the clutch spring strength, similar to what APMitchell has done on his turbo R32, now feeding 500+hp through the DSG (and way more than the 350nm specc'd limit).

The servicing cost of ~$400 for the 6 speed DSG every 60,000k is not excessive by any auto transmission service standards. But the lesser cost of the 7 speeder is better still.

Could it be that the 250Nm "limit" is not to do with stress on the gearbox per se, but instead, its ability to reliably change gears in a smooth and satisfactory fashion? So while it can cope with the extra Nm's without fear of damage, the average user may not be satisfied with the quality and smoothness of all the changes. Planned improvements to the software controlling the DSG may be able to alleviate this. Just a thought, based on limited observations with my tuned car.

Last 2 autos we had(2003 Peugeot and 2007 Honda) both had transmissions that were sealed for "life". Servicing costs zero. Of course, if it broke that would be expensive.
