7-speed S tronic.

[ER-3682]

I wonder Audi's 7-speed S tronic,is it 'almost' the same as VW 7-speed D.S.G.....?

[Shift_lock]

The VW 7 speed DSG is used on most VAG cars, which means most Skoda and Audi here also use the same transmission.

Not sure how much you know about transmissions in general; but to give you a quick summary of the differences:

 

VW DQ200:

-7 speed forward, 1 reverse

- Dual Single-plate Dry Clutches

-Transverse engine mounting only (engine cylinders go from side to side across the bay)

-Low fluid fill, lightweight for small applications (IE VW Polo)

-Maximum Torque capacity of 180 Ft-Lbs

 

Audi DL501 (equipped in the Q5):

-7 speed forward, 1 reverse

-Dual Multi-plate wet clutches

-Longitudinal engine mounting only (engine cylinders go from front to back across the bay)

-High fluid fill, dual separate oiling circuits (1 for controls, 1 for gears)

-Maximum torque capacity of 440 Ft-Lbs.

 

The "S Tronic" Audi transmission is much more robust than the VW 7 speed DSG. It does not suffer the heat and debris issues the regular DSGs can suffer, because the oil in the Audi 7 speed is not shared between the control systems and the gears; they each have their own separate oil paths, oil reservoir, and type of fluid.

 

However, low end model like A1 and A3 share the same engine 1.4T with VW Golf.

There is no way Audi is going to destroy its brand image by using the infamous dry 7 speed DSG.

 

Audi is a premium brand so they can up the cost for better quality. VW on the other hand is the budget wing in the Volkswagen AG, their aim is to bring down cost as much as possible which explains why they choose to moved from the more expensive wet DSG to the cheap but problematic dry DSG.

 

Audi's cars have either a wet dual clutch gear box or a conventional auto box. That is why you very seldom hear Audi having the same gearbox problems with VW

Is the A3 Sportback S tronic also not the same as the VW Golf 7's DSG.?

[Sg571958]

The new A3 uses the same 7 speed dry dual clutch - confirm from my Germany Colleague.

 

 

He don;t even trust the A6 7 speed wet clutch! He drives quattro manual A6!

Most German/Europeans like manual cars....

Really appreciate the input.

Actually Audi uses several different transmissions for their models.

 

8-speed ZF automatic transmission

8-speed multitronic Continuously Variable Transmission

7-speed S tronic transmission

6-speed Tiptronic automatic transmission

6-speed Manual transmission

6-speed R tronic automatic/manual transmission

6-speed R tronic automatic/manual transmission

1st one used by A8,2nd ones used on 2L A6,3rd ones used on 2L A4/& some A3[suspect same as VW DSG],4th ones used on older models,last one used in R8.

The A1 and A3 (up to 1.8 T) DO use the DQ200 7-speed dry clutch gearbox.

 

The A4, Q3 and Q5 etc use the 7-speed wet clutch gearbox, same as the Tiguan 2.0.

[Toeknee_33]

Apparently there is another VW 7-speed DSG gearbox DQ500 that is meant for transverse installations, and can take up to 500Nm. Its a wet clutch system and is used on the larger VWs like the Tiguan. Audi's version is called DL501 and its meant for longitudinal applications.

Sounds logical, but sadly, its not true. A1, A3 and Q3 are all clones of Polos and Golfs, which means they are identical under the skin. And Audi also uses CVT (A4 and A6) and single-clutch automated manuals (R8). Of course they also come in manual guises.

Correct, this is the 7-speed wet clutch gearbox I refered to above. It's actually 600Nm, not 500. Info from here: http://www.volkswagenag.com/content/vwcorp..._new_dq500.html

And how is the reliability of this gearbox with its twin oil chambers and multiple temp sensors? Or is it only the DQ200 that gives problems?
