Volkswagen today revealed the latest version of its DSG gearbox — a seven-speed system codenamed DQ200. It uses a pair of dry clutches in preference to the six-speed version’s twin wet clutches, providing an increase in efficiency and performance.
The six-speed DSG gearbox, which was introduced in 2003, uses a pair of clutches submerged in oil. The new seven-speed gearbox adopts a pair of dry, organic bonded friction linings that do not require cooling, making the drivetrain more efficient through the extra ratio.
.
For the first time the DSG gearbox has been mounted transversely. Measuring only 369 mm in length and weighing only 79 kg including the dual-mass flywheel the gearbox is remarkably compact. These modest proportions mean it can be applied to models from the Polo right up to the Passat and, in its current form, it is capable of coping with power outputs of up to 170 PS and 184 lbs ft of torque.
In adopting seven-speeds, Volkswagen engineers were able to lower first gear to improve acceleration from a standstill. By contrast seventh gear has been raised to act as an overdrive function making it ideal for motorway driving with the additional effect of raising economy and comfort levels.
The volume of oil contained within the gearbox has also been reduced by 75 per cent. The oil circuits are split into two in an effort to protect the lubrication’s purity. As with a conventional manual gearbox, one of the circuits is used for cooling and lubrication of the gear teeth, the second feeds oil to the gear actuators. Since the clutch does not require cooling the quantity of oil was reduced from seven litres in the six-speed DSG gearbox to only 1.7-litres in the new seven-speed system.
Production of the gearbox is set to start at the end of the year.

So this can’t be applied to the GTI? Hopefully they’ll make it stronger to handle the 208 ft lbs from the 2.0T.

Sounds awesome, I’ve always loved the DSG design, and I’ve been waiting for companies like Getrag to finally put some on the market for custom applications. This thing seriously needs more torque tolerance though.

BMW doesn’t have one already…we’re all waiting around for them to put one out as they have announced, but its still very much a no-show. We don’t even know what BMW will have their first dual clutch gearbox.

79 kg is still hella heavy when applied to small cars. It’d be a nice addition in large sport coupes though…

WEKS, yea I forgot to mention that bit which makes it a rather useless alternative to the traditional old manual even though I like the concept of a DSG.

the DSG is a cool tranny but a true sports car should have a 6 spd manual

I suppose it depends on your meaning of sport. If sports car = performance car, the DSG is the superior option. If sports car = fun car, most will go with the manual.
Manuals will probably die out in the near future, but I enjoy both.

That’s it? If 170 horsepower is the best VW can do then I’ll happily buy a car that offers 300 horsepower and a 6-speed manual. I had no idea. Oh well…

“Only” 79 kilograms and 184 ft./lbs. of torque capacity? Where’s the innovative insanity that all the Veedubbers are cheering about? Novelty wears off quickly and the consequences of premature action echo for a looooooong time.

Madcapp, what’s the smallest engine offered in the Passat? I’m not a VW follower, so I’m not sure, but the blurb above suggests that they’re intending to use the transmission in those as well. Last I checked, that had quite a wide range of larger engines and nothing smaller than a V6. Do the Euro models come with the smaller powerplants you suggested?

US based Passat has 2.0T 4 cyl, or 3.6L VR6. Euro models additionally get small weak stuff like a Non-turbo 2.0L and 1.6L 4 cylinders. This 7 speed DSG, in conjunction with the new 1.4TFSI and smaller diesels is just part of Volkswagens wise strategy to have very low consumption drivetrains available in response to high fuel prices. Other manufacturers would be very wise to follow this model.
VW is certianly not perceived the most premium brand out there, and their products are often misunderstood at first, but they are positioning themselves very well for the future and they do have world class engineering. There was a VW press release April 27th (exactly 1 month ago) that explains a little about this, and its good information to read.

VW has to make the transmissions they have NOW last longer to help them crawl up from the bottom of JD Power and Consumer Reports reliability.
A new complex trany is NOT going to help increase sales.

Get Real, you are a fool who has no clue about auto manufacturing. Volkswagen (and most other auto manufacturers) do not make their own transmissions. Instead, they buy them from dedicated transmission manufacturers. In the DSG case, the twin clutch assembly is a Borg-Warner supplied system, and the transmission partner is Getrag. When BMW finally gets around to introducing their twin clutch transmission (BMW calls it “ZSG” for Zero Shift Gearbox), guess what?…its going to be Borg-Warner and Getrag for the BMW system as well, no surprise there. If you like German cars, you need to pay attention to ALL brands collectively because they share many systems and suppliers and they are more interrelated than you think. And if you don’t know how a car is built, then you need to keep your piehole shut.

Has anyone seen the transmission made by the company ZeroShift?

They can make them in either manual or automatic and it seems like it would be a great alternative, I don’t know why more manufacturers haven’t looked into it.

I stand corrected Madcapp you hit it dead on. I had read in an older book that the old Austins were to use them so I thought it was a British design. Theres another system like the Zeroshift can’t think of it off the top of my head. I find it funny how most people on here get their facts from blogs and don’t read or are as passionate about automotive history as some of us

You must be ignorant also of all the problems people have with their BMW’s transmission failing. These are complaints from people who LOVE the car but hate the problems they have.
You are foolish for blindly following euro-trash cars.
JD-Power is reality.
Sorry you can’t see.

OK Get Real, lets look at the JD power initial quality survey…
http://www.jdpower.com/corporate/news/releases/charts/2006082a.gif
With the Exception of Land Rover, ALL 38 major brands are within 1 defect of each other in initial quality. #1 Porsche averages .91 defects per car, and #38 Isuzu averages 1.91 defects per car. There is no major differences in initial quality among brands…although there’s a huge misconception about quality, and a lot of money to be made promoting this misconception. Toyota averages 1.06 defects per car, but Chevrolet is only at 1.24 defects per car…not much difference at all, but everyone likes to pretend there is some major difference. The truth is that ALL cars are very similar to each other in initial quality, and after that, long term reliability is going to be more a factor of how the car is owned and cared for. And the final truth is that Get Real doesn’t know anything about cars and needs to keep his piehole shut because he keeps embarrasing himself by revealing his ignorance.

Oh by the way Get Real, since the #1 spot is held by both a German company and an integral part of the Volkswagen Group, it looks like your “euro-trash” theory is well, completely wrong.

You want to compare Chevy with Toyota ????
They have the same initial quality ???
You are so funny. I laugh, that is good.
Go to a used car lot and buy a 2 year old Chevy vs Toyota. You pay a big premium for the Toyota.
Perception vs Reality is hard cash, and the world revolves around cash.

Like you said earlier, look at the JD power survey. The difference in initial quality between Toyota and Chevrolet is 0.18 defects per car. Who would want a Toyota anyway? That’s the #1 brand for boring people.
