Audi's new S tronic gearbox can handle 406 lb.-ft. of torque
The Audi S tronic / Volkswagen DSG gearbox
The Europeans will first get the new gearbox in the Q5 SUV and the S5 coupe, where it'll supplant the 6-speed auto that's available as an option in the 2-door. Given the choice between Tiptronic S and this new S tronic, we'd happily choose the latter every time. Unfortunately, we won't be seeing it for the foreseeable future. While Audi plans to drop it into a number of Euro-spec models, including S and RS-series cars, the Tiptronic S will continue to be the offering for Americans who want a manumatic in vehicles such as the forthcoming Q5. Audi apparently thinks we'll find the shift action of the S tronic to be too harsh. If that's the automaker's worry, how about this: take the R tronic that's currently available in the R8, cast it into the ocean, and replace it with the the new, improved S tronic. Based on our experience, it might be exactly what the doctor ordered.

406, just check the source.
These dual clutch gearboxes are pretty awesome, or so I hear, should be the future of performance transmission and more

And oh yeah, the S5 looks HOT in that pic, classy and muscular, awesome

S5 is a hot car. Saw one on the highway the other day.
Kinda lame that those sexy LED DRL's have to turn off on the one side when the driver turns on that side signal to change lanes.
Interestingly enough I saw a newer PT Cruiser that did the same thing, sans the LEDs.
Is this some new law that you cannot have a DRL and a turn signal on at the same time? Or just car companies making the signal light more visable by turning off the DRL?

Your guess is correct; due to the proximity of the turn signal to the headlamp, many automakers now shut off then DRL lamp when the turn signal is activated to make the signal more visible. I used to see this all the time with Chrysler vehicles on the road and thought it was a prevalent fault until I found out the true reason.

does autoblog authors ever realize that Borg Warner never delivered a gearbox to VW Audi... they only deliver the clutch not the tranny..and they only deliver the clutch for the wet DSG, the dry clutch for the 7 speed DSG is delivered by LUK..all VW Audi tranny are build in the VW tranny plant in Kassel were they have already build more than one million DSG trannys!!!

This is not correct. The 7-speed FWD transmission in the small-engined (1.4L - 1.9L) VW cars is a dry DCT, with a DRY clutch supplied by LuK, as explained on their website.
The Audi S-Tronic 7-speed is a wet clutch design, similar to the original VW DSG.
A dry clutch would not be sufficient for a high-HP application like the S5! This is why the new Nissan GT-R, BMW M3, Porsche PDK, and Ferrari California transmissions all feature wet clutch design.
Just because the number of speeds is the same between the new VW and Audi transmissions, don't draw wrong conclusions, and spread misinformation!

@ Jason next time read more carefully!!!!!!!!!
I wrote the dry clutch for the 7speed DSG (DSG is only used by VW, Audi´s dual clutch tranny is called S-Tronic!!!!!!!!!) clutch is delivered by LUK.. I never claimed that the 7speed S-Tronic is a dry dual clutch tranny!!!!!!!!!!!!!
Read my comment down the list were I wrote that the Audi 7 speed S-tronic use two oils system to improve perfromance.
I only wanted to clear that Borg Warner only deliver the clutch disks a small part for the DSG tranny and that only for the 6speed wet dual clutch tranny!!!!!!!
Most authors of autoblog sound like that Borg Warner deliver the complete DSG tranny to VW/Audi and sometimes they sound that VW´s DSG is a Borg Warner development. Borg Warner only build one part of the DSG and that part was developt by by Audi/VW.

Yes, sorry, my reply was attached to the wrong OP. I realised this too late and could not delete the post. I had to repost it under the correct OP afterward.
You seem to know well about DCT.
BW supplies more than the clutch, however, to be clear. In addition to the clutches, BW supplies mechatronic control modules for many of the DCT on the market today. You are correct that there are many mistakes in the media reports, especially the online forums and journals, however.

Well, they're gonna have to do a hell of a lot better than that for the R8 V12 TDI.

Audi has already developt a 1000Nm(738ft.lbs.) dual clutch tranny for the possible R8 V12 TDI and all other midengine powered cars in the Volkswagen empire.. Murcielago, Gallardo, R8, future Bugatti, future Lamborghini and possible future midengine Porsche. At the moment they work hard to get it into payable production costs, this dual clutch tranny is the key to the R8 V12 TDI... if they manage to produce it for payable costs and the tranny gets green light from the managing board it is most likely that the R8 V12 TDI went into production and that this dual clutch find their way into all midengines cars from Volkswagen companys

stupid Audi and their stupid nonsense decisions. they make inane excuses to allow them to hold to a low status quo for their American deployments. Too harsh shifts? What a bunch of nonsense. Bring it here or GTFO.

Sadly when Audi interviews potential customers of Luxury cars in the United States, the research indicates that the average American is a pansy and doesn't want to feel the shifts. So thanks a lot to you few people who made the decision for all of us. I would have really liked that the Dual Clutch system was available here and now will never get the chance to enjoy!!!
Paul 3:55PM (7/23/2008)
I'm curious if the marketing group had actually driven a dual-clutch car. Mine (A3) is by far the smoothest auto transmission I've ever driven. The rev matching makes the shifts completely transparent. It is almost CVT smooth. Every now and then you get a hiccup and there's a little backwards roll when you first lift your foot from the brake on a hill, but otherwise it is far superior to a standard automatic.
Nope, again, I'm calling BS and sticking with cost as the driving factor in this decision.
Paul 12:41PM (7/23/2008)
It's got nothing to do with harsh shifting and everything to do with cost and the devaluation of the US dollar. Same problem with TDI and so many other cool technologies that never makes it stateside anymore. Talk to Mr. Bernanke...

We can also thank the EPA for making it incredibly expensive for manufacturers to offer more options for sale in the US. Every single engine/transmission/drive train has to be tested and certified individually, each for an astronomical cost.
It just isn't cost effective to offer options.

anyone know why is "provided by Borg Warner" written then crossed out?
Reply
JD 1:06PM (7/23/2008)
probably because it isn't provided by borg warner, even though they wrote that initially. It's a correction. You look at the comments? Try reading nagmashot's comment. This isn't really complicated. You never seen a strikethrough before or something?
Benfolio 2:19PM (7/23/2008)
Yeah, same reason why the 402 lb-ft in the story got changed to 406 lb-ft to match the title (and the actual spec).
It's just an edit.
