Was surfing the net again after work today. And found this bunch of info.

Enjoy. Sorry it's really long

Volkswagen DSG - Automatically shifting 6-speed gearbox for more driving fun

Dynamics and fuel consumption superior to manual gearbox
To be used for the first time in the top Golf model, the sporty R32
Wolfsburg. Volkswagen presents a world-wide technical innovation: the sporty and economical automatic gearbox “DSG”. This gearbox with integrated dual clutch will be used for the first time in the Golf R32. In the course of the year 2003, its use will be extended to other production series - primarily in conjunction with high-torque engines. With the new dual-clutch gearbox, Volkswagen continues its powertrain offensive across all classes.
Volkswagen was one of the first manufacturers to offer manual 6-speed gearboxes as optional equipment in the volume segment for certain production series and models. In the luxury class, a new 6-speed automatic for the Touareg V10 TDI will be introduced in mid-September. Early in October, with the New Beetle Cabriolet, Volkswagen became the first manufacturer to offer a transversally installed 6-speed automatic gearbox in the compact class – a configuration long considered impossible. With the DSG, the company now extends this spectrum by a technically completely new type of gearbox.

Volkswagen invested 150 million Euro in the DSG production system; up to 1,000 units can be produced daily in the gearbox factory in Kassel.

The DSG will be manufactured at the Volkswagen plant in Kassel, where 150 million Euro were invested in production. At full capacity, up to 1,000 DSG can be produced per day.

The gearbox has been designed to fulfil the demands of European customers for sporty driving and fuel economy. One significant difference to the familiar automatic gearboxes which are established especially in the USA in all classes: The DSG does not employ a torque converter for a standing start. Nor is the DSG a derivative of the automated manual transmission used in the Lupo 3L TDI. Rather, the DSG engineers took a technically completely new and revolutionary path by harmonising the agility of a manual transmission with the ease of a conventional automatic gearbox.

The DSG is significantly superior to the manual gearbox regarding fuel economy and performance, speed and ease of shifting as well as driving fun.

This new Volkswagen gearbox offers a genuine alternative in particular to those drivers who up to now have preferred manual gearboxes, because the DSG suffers no disadvantage in terms of fuel economy or performance. On the contrary: with identical acceleration and top speed, it shifts as smoothly as the best conventionally built automatic gearboxes; in addition, manual shifting is possible using the Tiptronic function or, in the Golf R32, buttons in the steering wheel. And shifting occurs faster and more “crisply” than possible up to now with either manual or automatic gearboxes, and without interrupting tractive power.


Technology overview

Volkswagen DSG - Gearshifts take only a few hundredths of a second


In the DSG, the next gear is permanently engaged and ready for activation
DSG matches revs in the finest sporting fashion during downshifts
As one of its outstanding design characteristics, the transversally installed DSG gearbox possesses two wet clutches (greater thermal capacity and better regulation than dry clutches), the pressure of which is hydraulically regulated. The so-called clutch 1 (C1) serves the odd gears (plus reverse) and clutch 2 (C2), the even ones. Therefore, for all intents and purposes, one must speak of two parallel gearboxes in one. A consequence of this elaborate clutch management: during a shift, there is no more interruption of tractive power, typical of an automated manual transmission. Consequently an incomparably dynamic and, at the same time, smooth shift feeling with a high degree of comfort is conveyed The high efficiency of this gearbox is very close to that of the classic manual gearbox. Together with Mechatronic, an intelligent hydraulic and electronic gearbox control, the two wet clutches with two input and output shafts are responsible. This interconnection enables the next higher gear permanently to be engaged and ready for activation. And like lightning, to be sure. For example: While the car is being driving in third gear, fourth gear is already engaged, but is not yet active. As soon as the ideal shift point is reached, the clutch for third gear opens while the other closes, activating fourth gear. The opening and closing of the clutches coincide in the process, producing the smooth shift already mentioned above. The entire shift process is completed in the especially short time of 3 to 4 hundredths of a second.

Alternatively, the driver can shift the gearbox crisply using Tiptronic; the Golf R32 with DSG offers additional switch buttons in the steering wheel.

Parallel to the fully automatic shift programs “D” and “S”, the DSG has a Tiptronic function which enables manual shifting. Beyond that, the driver of a Golf R32 can select gears using shift buttons in the steering wheel. In both cases, the result is a shift feeling marked not only by superior comfort but also by extreme fun when shifting. Drivers with sporty ambitions will experience for the first time that gears can be changed as with the press of a button. And what's more: In the even sportier mode (position “S”), the engine and gearbox control units even activate a form of rev-matching, which further enhances the shift dynamics: Using wheel speeds provided by the ABS, the gearbox control unit ensures that no unintended up-shift occurs in the middle of a curve.

DSG stands for a new generation of gearboxes offering the maximum of agility; better fuel economy and acceleration better than a manual gearbox

It is generally true that an engine coupled to the DSG is always in the position spontaneously to have the desired tractive power available due to the fast, independent gear change. No less decisive is the fact that the new gearbox provides the great agility of a manual transmission but undercuts the latter substantially in fuel economy. The R32 with DSG consumes only 10.2 litres Super Plus petrol per 100 km, undercutting the manual version by about one and a half litres (11.5). Such extreme fuel reduction can otherwise be achieved only through the use of extremely lightweight building materials. Acceleration is tangibly better than for a manual. Equipped with DSG and an integrated launch control (an electronic start program), the Golf R32 sprints to 100 km/h (about 61 mph) in only 6.4 seconds (with manual gearbox in 6.6 seconds). The top speed of 247 km/h (about 151 mph) is the same.


Volkswagen is the first manufacturer to develop a production-ready gearbox of this type; without the Mechatronic module, the DSG in this form would be unimaginable.

With the DSG, Volkswagen is the first manufacturer to develop a dual-clutch gearbox ready for production. Such gearboxes have already been used in motor sports, but the uncomfortable shifting due to inadequate means of mechanical and electronic control made them unacceptable for use in production cars. In its own undertaking, Volkswagen solved the problem of exacting demands in design; in addition to numerous new hydraulic components, a complex Mechatronic was developed which first made possible the DSG as it is now being introduced in the Golf R32.

Volkswagen DSG - Mechanics and electronics are perfectly united in the DSG

This DSG technology is nothing new to VW/AUDI world though. It was used in the RALLY audi quattro over 10 years ago.


Now it is just better and finally public road authorized.
Read that initially on TEX when the first R32 rumors surfaced.

DSG is good ,it's halve automatic ,halve manual ,and it's easier for ride ,och,I hope that vw use it for the multivan too ..
and another models !

When i go to FL this weekend, I get to try out my dads Z4 with BMW's new SMG 6 speed tranny with the padal shifting. I'll report back on monday on what i thoght of it.
