What is DSG in a car: features of a preselective robotic gearbox with two clutches. Gearbox dsg - repair of automatic transmission dsg volkswagen, skoda, replacement of mechatronics, clutch All about the gearbox dsg 7

More recently, manufacturers have begun to actively install robotic gearboxes on cars instead of the usual and. As you know, a robot (RKPP) is a mechanical transmission, in which automatic on / off is implemented, and without the participation of the driver, the desired gear is selected and turned on.

In other words, a box - a robot is another type of automated transmission, while it is cheaper to manufacture, simpler in design, and provides high fuel efficiency.

DSG robotic gearbox (DSG): what is it

So, in order to understand what DSG is, you first need to consider the main types of robotic boxes. In a nutshell, a robotic gearbox can be either a "single disk" robot (for example) or a preselective robotic gearbox with two clutches.

An ordinary robot, which has only one clutch, is similar in design to, while the engagement / disengagement of the clutch and the gears are controlled by the automatic (with the help of electro and hydraulic servos under the control of the ECU by the box).

This design is simple, the gearbox itself is quite reliable, however, when shifting gears, certain discomfort arises, the car "bites" its nose during intensive acceleration, a single-disk robot often delays the inclusion of a low and high gear, etc. Also, during operation, the clutch itself wears out quickly.

DSG box: device and principle of operation

In turn, DSG (Direct Shift Gearbox) is a direct shift gearbox developed by Volkswagen. To put it simply, it's still the same manual transmission, but there are already two clutches.

Moreover, in such a box, two manual transmissions are combined at once in one case. Each of these conventional boxes has its own clutch disc. In this case, one box is responsible only for even transmissions, while the other for odd ones.

To switch up or down a step, the driver (in the case of a manual transmission) or ECU (in the case of a single-disk robot) disconnects the clutch disc from the flywheel, then engages the gear, and then reconnects the clutch disc. At the same time, it is not transmitted to the wheels until the clutch disc is connected to, the car noticeably loses in dynamics, and fuel consumption increases.

If we talk about DSG, for example, when a car with such a gearbox accelerates, the clutch of an odd row of gears is attached to the rotating flywheel, while the disc of the even row is in an open form. Further, while the car is accelerating in first gear, the ECU (mechatronic unit) gives the command to turn on the second on an even row.

Then, already at the moment of switching, the disc of the odd row is disconnected and the disc of the even row is turned on, while the next gear is similarly “preparing” to be switched on already in advance.

It turns out that if the car moves, for example, in 2nd gear and then picks up speed, on command of the ECU, 3rd gear will also be almost completely engaged. As a result, when the moment of upshifting comes, a full shift from 2nd to 3rd takes a fraction of a second, gears change very quickly, and the power flow is practically not interrupted at the moment of shifting.

This feature of the work is clearly reflected in the name of this type of gearbox, since a box with two clutches is usually called preselective (preselection and partial inclusion of the next higher or lower gear). As a result, the DSG transmission offers the high level of comfort inherent in automatic transmissions and variators, as well as the dynamics and fuel efficiency of traditional mechanics.

Types of DSG boxes: DSG-6 and DSG-7

DSG boxes are 6 and 7-speed. In this case, DSG 6 is "wet", while DSG 7 is "dry". The first version is designed for higher torque and is installed on powerful cars of the VAG concern. The DSG 7 version is installed on cars with less powerful internal combustion engines. The first to be developed was the six-speed DSG 6.

The clutch in such a box works in an oil bath. For this reason, this type of gearbox is called "wet". The disadvantages include the loss of power due to the large amount of oil and the need to implement its supply. The DSG7 version appeared later, it has a "dry" clutch. At the same time, the reliability of this design has decreased, this type of gearbox has more problems and less resource.

DSG resource and DSG boxes malfunctions

Let's start with the problems. Most often, the problem is expressed in the form of jolts when changing gears. The reason is too sharp clutch engagement, the car starts to twitch. Also, when shifting gears, there may be shocks, grinding noise. Another option may be the problem of loss of traction on a car with DSG, and right on the move.

As a rule, such malfunctions are more inherent in the DSG 7 with a dry clutch. Such a clutch is subject to rapid wear, in parallel, certain malfunctions are also given by Mechatronic (ECU box).

In the list of other problems associated with this type of gearbox, it is necessary to highlight the wear of the shaft sleeve, problems with the clutch release fork, electrical problems (contacts, failure of sensors, etc.). At the same time, it is important to understand that often for a non-warranty vehicle, DSG diagnostics and repairs are expensive, and the cost of spare parts is also high.

If we talk about the resource, it should be noted that at the initial stage, no special problems with DSG 6 were observed on average, up to 150-200 thousand km. However, after many VAG models began to massively install DSG 7, the number of requests in warranty period on runs 60-80 thousand km. increased markedly.

As a result, the manufacturer launched a customer support program extending the full DSG 7 gearbox warranty to 5 years or 150,000 km, whichever comes first. Within the framework of this program, all repair work (up to complete replacement unit) were performed free of charge.

In the future, the program was curtailed, citing the fact that VAG engineers finalized the software for the control unit, made certain changes to the clutch design, that is, made DSG 7 more reliable.

One way or another, taking into account the information provided, it is quite logical to assume that the average resource of DSG 6 is about 200 thousand km, while for DSG 7 this figure is about 150 thousand km.

As you can see, a serviceable DSG gearbox is capable of providing good acceleration dynamics, comfort and fuel efficiency. In other words, the main tasks set for the developers in the conditions of the fuel crisis and tough environmental standards have been solved.

At the same time, the issue of resource and reliability was deliberately pushed into the background. In simple words, even the relatively reliable DSG 6 quickly replaced DSG 7. At the same time, given the obvious problems, VAG still preferred an expensive program of warranty repairs and the active dissemination of information about DSG7 modifications in order to increase its reliability to the banal abandonment of this gearbox.

In other words, instead of going back to DSG 6 or the time-tested hydromechanical automatic, the manufacturer continues to install DSG7 on many popular Volkswagen models, Skoda, Audi, etc., claiming that the reliability of the box has improved significantly.

In practice, the feasibility of using a DSG is questioned by many experienced car enthusiasts. Moreover, if we are talking about DSG 6, the real mileage does not exceed 100 thousand km. and the checkpoint is working properly, then such a car can still be considered for purchase.

As for the DSG7, especially the first years of production, even if such a gearbox works normally, this does not mean that the residual resource is still large enough. In other words, you need to immediately prepare for a gearbox repair, and an expensive one.

We add that although there is nothing special to break in the box itself (shafts, gears and other elements "run" for a long time), however, problems may arise with the clutch assembly, sensors, actuators, electronic control unit, wiring and a number of other mechanisms, parts and assemblies ...

At the same time, in some cases, it may be enough to reflash the ECU and replace the clutch, while in others it is necessary to change expensive and officially non-repairable units.

Finally, we note that another disadvantage of DSG, especially DSG7, is their low liquidity at secondary market... This means that such a car, especially a premium model with low mileage, can be bought at a high price, but it will not be profitable to sell it later.

To put it simply, most motorists today are well aware of the problems of this box and simply do not consider cars with the specified type of gearbox. Another option would be to try to significantly reduce the cost of a used DSG car during bargaining. The reason is quite obvious, since a potential buyer separately takes into account the cost of a possible repair of a preselective robot, and such repair may be required very soon.

1. What is DSG box

The driver selects the gears, and the electronics itself controls the clutch and gives the command to change gears. A distinctive feature of such units is a double clutch and five shafts.

This solution made it possible to achieve the same acceleration and set times maximum speed, as with a conventional manual transmission. It would be correct to say that DSG is the next step in the development of a manual transmission. Such nodes are also often called "robots".

2. The device and technical subtleties of DSG boxes

DSG boxes are divided into two types - DSG-6 and DSG-7, the first is a six-speed version, the second is a seven-speed one.

DSG-6 has a large torque and operates on a “wet” principle. The mechanical parts are immersed in an oil bath, while the oil circulates, thereby cooling the clutch assemblies and discs.

Such gearboxes are installed on vehicles with increased power:

Volkswagen Golf, Volkswagen Eos $
S koda Octavia;
Audi TT, AUDI Q3.

DSG 7 is a dry box. Differences from DSG 6 - in reduced torque and dry clutch, transmission oil only used to lubricate the clutch discs. They are installed on low-power cars or on those in which the torque does not matter much. Due to the lack of normal cooling, they are disliked by motorists.

Examples of cars with seven-speed "robots":

Volkswagen passat, Volkswagen Transporter;
Skoda Fabia, some Octavia;
Audi A3.

The principle of operation of robotic boxes ("robots") is as follows:

When the first gear is turned on, its gear is blocked, the clutch is closed and the moment is transmitted to the gearbox, at the same time the gears of the second gear are blocked. It turns out that two gears work simultaneously, but the second clutch is open and ready to be engaged. By command on-board computer the discs of one clutch open and the other is turned on. Next, the gears of the third gear are blocked. As a result, the box is constantly ready to switch to the next gear. When slowing down, the cycle repeats, only in the opposite direction.

The common unit of such boxes is mechatronics, a unit that includes sensors, hydraulics, and electronic components. He monitors the readings of the oil pressure, the position of the gears, speed and other parameters and, based on this, makes a decision on the transition to an up or down gear.

3. Advantages and disadvantages of "robots"

The robotic gearbox has many pros and cons.

The pluses include:

almost instant gear change;
Manufacturers declare fuel economy (controversial, perhaps in comparison with a conventional "automatic");
There is no engine power take-off, as with manual transmission control;
Manual control.

There are also many disadvantages:

The repair cost is high;
Unreliable mechanical part even in newer models;
Expensive and complicated oil change procedure in DSG-6 boxes;
Poorly tolerates aggressive driving style.
cars with such a box are more expensive than conventional hydromechanical "automatic" and "mechanics".

For example, we will give a budgetary foreign car Skoda Octavia with an engine capacity of 1.4 liters.

The price for a complete set with mechanics is 1,034 thousand rubles, they already want 1,074 thousand rubles for a box with DSG, however, the manufacturer claims a fuel economy of 0.1 liters for every hundred kilometers. In a dealership, a "robot" will cost 40-60 thousand more expensive than conventional mechanics, 10-20 thousand more expensive than an automatic machine.

4. Opinions and reviews

Feedback from the owners of such cars is extremely contradictory. On the one hand, the barricades are satisfied with the choice of motorists, on the other hand, they are disappointed and trying to dissuade them from such an ambiguous acquisition. The State Duma even recorded an attempt to completely ban DSG 7 boxes in Russia. The argument was the concern for citizens, the deputies expressed the opinion that such a box is not safe for drivers. Fortunately, it didn’t even come to an initial hearing.

DSG proponents cite arguments such as “correcting mistakes” by DSG manufacturers (dubious merit), fast gear changes that do not depend on driving skill, low fuel economy, stable operation at low temperatures, positive dynamics. Ill-wishers are countered by the fact that they have incorrectly read the instructions for the car. Indeed, manufacturers recommend, in contrast to hydromechanics, to include neutral in traffic jams or at traffic lights. However, these are just tips.

There are much more opponents and more weighty arguments. Unreliability of software, difficult maintainability, often it is impossible to repair at all, the entire unit changes, and this affects the cost. "Garage" repairs are excluded, if even an ordinary automatic transmission can be repaired in a car workshop with competent employees and a set of tools, then no one will take on DSG except for official dealers. Women complain about rolling back in traffic jams, men complain about the impossibility of a quick start from a traffic light (a tribute to reliability, when the first gear is connected, the box "thinks").

At the second speed, vibrations are felt, extraneous noises are heard in the box. A common phenomenon is a breakdown due to firmware, for example, "brains" stop recognizing even transmissions. It is believed that such systems are poorly compatible with gasoline, behave a little better with diesel fuel... In the heat on "dry" boxes clutch discs overheat, cannot be repaired, only for replacement. It is not for nothing that the people say this: DSG - Two Clutches a Year.

There are far more bad reviews than positive ones. The negative nature of the responses is clearly visible. On the other hand, if everything were really so bad with them, such boxes would not have received such distribution, and judging by the models on which they are installed, there are still a lot of them. Perhaps auto concerns do not admit their mistakes, again, re-equipment of conveyors is a costly business, but making people believe in quality and reliability is the work of marketers and PR services.

5. Conclusions

The decision on choosing a robotic gearbox is made exclusively by the future owner. If you are not a fan of aggressive driving, you are ready to spend authorized dealer, you do not like the "lethargy" of the machines, but you also have no desire to lose comfort due to the clutch pedal - DSG is fine. Again, in pursuit of a customer, such boxes usually come with an increased warranty. For example, Volkswagen claims 150 thousand kilometers without repair. Those who like to leave abruptly from a traffic light are better off looking in the direction of the "mechanics". If small jolts and fuel consumption are not critical, buy a car with a conventional automatic transmission.

In Russian conditions, DSG does not take root very well. Perhaps, soon the engineers of corporations will find a solution to many problems, as has happened more than once, but so far "robots" are the most common lottery. Play it or not - the choice is yours. But if the question arose only about the DSG, then the choice of a six-speed model is preferable in terms of reliability and dynamics.

What is DSG? From German, the abbreviation DSG stands for "direct transmission" (Direkt Schalt Getriebe). It is often called "preselective", that is, it is able to keep ready gears for the next shift.

The idea of creating such a checkpoint belongs to the French inventor Adolphe Kegresse. In the 1930s, an automotive engineer collaborated with Citroen. He proposed to install a unit with two clutches and hydromechanical control on the front-wheel drive Citroen Traction Avant. The new transmission was not widely used due to its complex design.

The technical consultant Volkswagen Favorite Hoff Maxim Ponomarenko spoke about the advantages and features of the box.

How DSG works

The fundamental difference between the preselective automatic transmission and the others is in two clutches that quickly change gears. In "mechanics" or robotic box to change gear, the clutch disc is disconnected from the flywheel, the driver or robotic computer selects the desired "speed", and then the disc gets into place. During this time, the torque is not transmitted to the box and the car loses its dynamics.

DSG eliminates power dips. At the heart of the box is the work of two shafts located coaxially: the first is hollow, and the second is inside it. The engine is connected to each of them through its own, separate multi-plate clutch - also external and internal. On the primary, that is, the external shaft, gears of even gears (2-, 4-, 6th) are fixed, on the internal - odd - 1-, 3-, 5th and gear reverse.

When the car starts, a disc with an odd row is pressed against the rotating flywheel, and the disc with even "speeds" is open. During acceleration, the computing unit of the box gives the command to prepare the second gear, so that at the moment it is turned on, disconnect the disk of the odd row and immediately start up the disk of the even one. Tuned shift control ensures no loss of torque.

The robotic gearbox DSG 6 entered the Volkswagen conveyor in 2003. The dual clutch on it worked in an oil bath, receiving the name "wet". The oil in such a box takes away some of the power, increasing fuel consumption. In 2008, the German automaker introduced the seven-speed DSG 7 with a dry clutch.

DSG Benefits

The DSG gearbox, due to the optimal modes of inclusion of the required "speeds", allows to reduce fuel consumption. Cars with it consume about 10% less fuel than cars on which regular box gear shifting.
A distinctive feature of all such transmissions is dynamic acceleration. To change the gear up, the box needs only 8 ms, it does not have the rubber traction effect of hydromechanical automatic gearboxes.
You can drive DSG in manual mode, that is, manually change gears.
Such an automatic transmission is 20% lighter than a similar hydromechanical transmission.

Disadvantages of DSG

The cost of automatic transmission affects the price of a car, significantly increasing it.
An expensive oil change (on a six-speed box) every 60 thousand kilometers. The total volume is 6.5 liters.

The preselective box is installed on different models and brands united under the name of Volkswagen: Audi TT (A1, A3, A4, S4, A5, A7, A6, Q5, R8), SEAT Ibiza (León, Altea), Škoda Octavia (Superb, Yeti), Volkswagen Polo ( Golf, Jetta, Touran, New Beetle, Passat, Passat CC, Sharan, Scirocco, Caddy).

DSG Extended Warranty

Among many car owners, the dubious glory of the double-clutch box has been entrenched. The DSG name itself has become a symbol of an unreliable design with costly repairs. In fact, Volkswagen has long since taken control of the situation. An important step towards quality control is a large-scale service campaign.

The concern gives an extended warranty for seven-speed gearboxes manufactured before January 1, 2014. According to representatives of the carmaker, the indicated period corresponds to the appearance on the conveyor of a modernized transmission without typical problems of the last generation. Special conditions of service are limited to 150 thousand mileage or 5 years of age of the mechanism. The service offer includes a replacement synthetic oil mineral - less aggressive towards electronic components. In this case, the firmware of the automatic gearbox control unit is updated. Found faults are eliminated free of charge - this applies to repairs, replacement of individual elements or the transmission assembly.

In any case, you should not be afraid of the abbreviation DSG: with the proper level of service, it will not let you down, and in terms of the number of advantages, the “smart robot” outperforms the classic automatic transmission. And the DSG box will require less money for repairs in comparison with a conventional "automatic".

What malfunctions are typical for DSG?

The most common problem is the jolts when changing gears accompanying the movement. The clutch discs close too sharply and the car jerks. The second known drawback is vibration at start, clanking, grinding and other extraneous noises during speed changes.

The main reason for the incorrect operation of the seven-speed transmission is its "dry" clutch. It wears out quickly due to severe operating conditions in dense city traffic, with congestion at low speeds. Therefore, the question "how to operate the DSG?" there is one obvious answer - to avoid the "gas-brake" mode, because the main enemy of the robot is a traffic jam.

Among other problems: wear on shaft bushings, clutch release forks, broken solenoid contacts, dirt on the sensors and oil in antifreeze.

How to determine a DSG malfunction when buying a used car?

Individual gears do not turn on - the box "jumps" them.
Gear shifting is accompanied by blows - the box "kicks".
There is a hum when moving.
The car vibrates at the start.
Inspection on the lift shows oil leaking from the box.

If there is a suspicion of incorrect operation of the box, it is worth ordering an additional check, or postponing this option.

Many modern cars equipped with a DSG gearbox. It is installed on passenger cars B and C class. It can also be found in cars of class D and higher (a six-speed type of product is installed on powerful cars). Therefore, car owners want to know what a DSG transmission is and how it differs from its mechanical and automatic predecessors.

The DSG gearbox is a robotic equipment equipped with two clutches and associated two rows of gears. This state-of-the-art device is available in six-speed and seven-speed versions.

DSG structure

double clutch;
main gear;

control system.

How DSG works

This gearbox sequentially includes the transmission of two rows. That is, when one of the gears is working, the next one is always selected, which means it is ready for use. Such a scheme of work provides switching without interrupting the power flow. This significantly increases the capabilities of the box, in comparison with its mechanical and automatic counterparts. After all, an engine with such a gearbox does not idle, fuel is consumed much more slowly, and the car gets improved acceleration characteristics.

The device is six-speed and seven-speed DSG

The dual clutch is needed to transfer torque to two rows of gears. The seven-speed equipment contains two friction clutches. In the six-speed version of the gearbox, the clutch is complemented by a drive disc connected to the flywheel and two friction clutches connected to the rows of gears through the main hub. In addition, the seven-speed and six-speed DSG models differ from each other in the type of clutch. The seven-speed uses a dry-type clutch complemented by an electric pump. This design of the box allows you to reduce oil consumption and improve engine efficiency. The six-speed DSG uses a wet clutch. It needs a lot of oil, but this principle of operation can significantly increase the service life of the equipment.

Each row of gears in the box is a primary and secondary row, equipped with gear blocks. During their operation, the second row controls the even gears, and the first one controls the odd and reverse gears. The input shaft in the second row is a hollow device that is fitted onto a similar shaft in the first row. In this case, both input shafts are located coaxially.

The gears of the primary and secondary shafts also have a different principle of operation. Those of them that are on the input shafts are rigidly connected to the shaft itself. In contrast, the gears on the secondary shafts rotate freely, and between them there are synchronizers that include the desired gear. In addition, the DSG gearbox is equipped with a reverse gear on the intermediate shaft. This device is required for reverse movement. The output shafts also contain drive gears, which are responsible for the final drive.

Gear shifting and clutch control are controlled by an advanced control system. It consists of:

An electro-hydraulic unit responsible for the operation of the hydraulic control circuit. This block consists of solenoid valves, multiplexer, directional spool and pressure control valves. Solenoid valves are used for gear shifting. The distributor spools are controlled by a special selector lever. Pressure control valves are essential for the operation of the friction clutches. And the multiplexer controls the gear shift cylinders (8 cylinders in total) using solenoid valves. Some of the hydraulic cylinders work in the initial position of the multiplexer, and the other part - in its working position. During this process, the same solenoid valves are used.
An electronic control unit that ensures the operation of the system in accordance with the signals of the sensors.
Input sensors that monitor the speed of the DSG output and input. The sensors also monitor oil temperature and pressure, and the location of the shift forks.

Pros and cons of DSG

Based on the characteristics discussed above, the pros and cons of the DSG gearbox can be distinguished.

Its advantages include:

no loss of engine power and its efficiency;
increased acceleration speed;
balance of fuel use (a car equipped with DSG consumes fuel 10% more efficiently than a car with a manual or simple automatic transmission);
the function of shifting gears in manual and automatic modes (this possibility is not even available in every automatic gearbox).

Among the disadvantages of this gearbox are:

high cost of the car (compared to cars equipped with conventional gearboxes);
the complexity of the design, which is badly reflected in the repair of the gearbox (in case of serious breakdowns, you will have to pay a large amount of money for a new gearbox, since the old one cannot be repaired);
negative impact on the control system of frequent temperature changes (such changes cannot be avoided when using DSG, therefore the gearbox fails faster than mechanical or automatic);
the impossibility of repairing the control system and the need for new costs for its replacement;
excessive overheating of the preselector.

These advantages have allowed DSG to become the most popular gearbox in recent years. Therefore, many were equipped with it. cars... For example, Audi Q5 and R8, SEAT Ibiza, León and Altea, Škoda Yeti and Octavia, Volkswagen Passat CC, Tiguan and Caddy, as well as many other cars from well-known world manufacturers.

It is also worth highlighting the disadvantages inherent only in six-speed or only seven-speed gearboxes. For example, a seven-speed DSG fails faster than a six-speed. This is due to the peculiarities of the dry clutch operation. In addition, in cars equipped with a seven-speed gearbox, jerking may be observed during the transition from first gear to second. However, this disadvantage is not common to all DSGs and is very rare.

Despite all the shortcomings, DSG is much more convenient than any of its predecessors. It makes your car easier to drive and improves specifications... Therefore, feel free to buy a car with this gearbox and do not think about possible problems... With such a modern device, you can define your riding style and fix it using the selector. By doing this, you will save yourself further contact with the transmission. But do not forget to monitor the correctness of its operation and immediately contact the car service if you find twitching, noise and other signs of equipment failure.

Volkswagen's DSG transmission was ahead of its time. As one of the pioneers in the automotive market, Volkswagen has developed a DSG for series production. The DSG gearbox with non-interrupting power flow makes driving a pleasant experience, allowing dynamic acceleration on the highway without jerking.

The DSG gearbox combines strengths automatic and manual transmissions, automatically choosing the optimal transmission mode. This transmission allows to achieve significant fuel economy, as it always "selects" the lowest cost and at the same time the most efficient operating mode power unit... The epitome of ideal efficiency: when the power output of the engine is converted directly into speed.

The main advantage of the DSG is smooth acceleration without interrupting the power flow during gear changes. DSG provides direct gear shifting, dynamic acceleration for sporty travel, and reduced fuel consumption.

The Volkswagen DSG is a 6- or 7-speed gearbox for all vehicle classes Volkswagen makes and is therefore of great interest to buyers.

Sports alternative to manual transmission

Based on the results of the drive tests carried out, the new Volkswagen DSG is as dynamic as the manual transmission. This becomes clear at a glance at the speedometer needle: only a DSG-equipped vehicle can accelerate so smoothly to top speed.

With this acceleration, the driver enjoys a sporty driving experience, and smooth gear changes will increase the level of comfort. In addition, in everyday situations, such as when overtaking, the DSG improves safety with large reserves of power.

The dry-clutch transmission offers freedom of choice for any driving style. DSG is more than a simple automatic transmission. It combines the advantages of an automatic and a manual transmission. This is expressed in the fact that the driver can make a choice twice: first he selects the mode DSG work- normal or athletic. He then chooses between automatic and manual gear shifting.

Normal DSG Mode

The robotic gearbox "reads" the driver's thoughts. When the gearshift lever is turned on to the "D", "Drive" position, the "normal mode" DSG is selected. At the same time, the necessary gears have already been selected in the box, which switch automatically in fractions of a second and without interrupting the power flow. This is the best mode for comfortable driving, since gear changes are imperceptible and no additional action from the driver is required.

DSG Sport Mode

When transferring the gearbox to sport mode"S" ("Sport") the ECM maintains low gears. Upshifting does not occur until the vehicle is at a higher speed and the engine is cranked up.

Selection of gear ratios

Optimum shift timing is achieved with the best selection gear ratios... Accurate selection of gear ratios allows you to achieve the best dynamic characteristics of the transmission. The gearbox control unit selects the optimum shift point depending on the activated mode, engine speed, vehicle speed and accelerator pedal position.

As a result, power losses can be avoided and the economy can be increased.

Reduced fuel consumption

With this responsibility to its customers in mind, Volkswagen has developed an innovative DSG transmission that saves fuel and reduces emissions.

In combination with TSI engine The DSG gearbox reduces fuel consumption by 22%, thus reducing CO2 emissions. Even compared to the classic mechanical box DSG transmissions provide significant fuel savings of up to 10%.

Benefits for car owners

Two-clutch transmission design solutions are offered for both small and high-end vehicles: 7-speed DSG for engines with torque up to 250 Nm is more suitable for small and medium-sized cars, such as Volkswagen Polo sedan in the GT, Volkswagen Passat B8, or Volkswagen Jetta in the Trendline and Highline trim levels. The 6-speed DSG gearbox for engines up to 350 Nm meets the expectations of buyers interested in high-end vehicles with more powerful engines, such as Volkswagen tiguan 1.4TSI BlueMotion.

With the DSG, Volkswagen has provided drivers who prefer a dynamic, sporty driving style with acceleration without interrupting the flow of power, with almost imperceptible gear changes.
The DSG gearbox is important for those who care about the environment, which helps reduce fuel consumption and CO2 emissions.
Drivers who spend a lot of time behind the wheel can relax while driving their DSG vehicle while enjoying the ease of driving.
New high-tech developments from Volkswagen have enabled DSG to achieve the best possible combination of the performance advantages of mechanical and automatic transmission gear.
