Unveiled at the end of June 2015 in Goodwood, you may have noticed the sequential gearbox, which has long been an integral part of sports and supercars. Since some karakumniks are interested in the device and features of this type of checkpoint, I will tell you about it. Sequential checkpoint differs in the possibility of only sequential switching between gears. In other words, the driver can change only one gear higher or lower than the one used, without jumping over the rest, as can be done in a classic manual gearbox with a search shift principle. I propose to get acquainted with this type of gearbox in more detail and dispel a couple of misconceptions associated with sequential gearboxes.

The principle of operation of the sequential gearbox

As we have already found out, the gears of this type of transmission are switched only one by one, in a strictly specified sequence. And since the sequential gearbox is built on the basis of a mechanical one, we will make references according to the principle of operation to the manual gearbox.

At first, the sequential gearbox is characterized by the absence of a clutch pedal, which, first of all, will please drivers who are not sophisticated by experience. This greatly facilitates driving, because constant dancing with your left foot on the clutch pedal is, frankly, an amateur's business. The clutch is not controlled by the driver, but by the electronic unit, which receives a signal from sensors that read the pressure on the gas pedal and directly engage a specific gear. As the saying goes, it's a matter of technology. When the box receives a command from the electronic unit, a new signal about the used vehicle speed is transmitted to the progressive unit using special sensors. The progressive block is the last resort where the speed mode is adjusted based on various indicators: from engine speed to the operation of the air conditioner.

Secondly, in the sequential gearbox, spur gears are used. They give out a greater efficiency when compared with helical gears from manual transmissions. This is because the helical gears have more frictional losses. But spur gears are also capable of transmitting less torque, therefore, in sequential gearboxes, gears of a larger size are often used to compensate for this disadvantage.

Finally, third distinguishing feature sequential transmission is the presence of hydraulic servo drives, with the help of which there is a shift between gears. Nowadays, hydraulic servos are often associated with robotic gearboxes, but this is not the case. The latter uses electrical ones.
Evgeny Travnikov talks about one of the variants of the sequential box in his video:

Advantages and disadvantages of sequential gearbox

Now that we have an idea of ​​the principle of operation of the mentioned transmission, let's figure out what to expect from it.

Advantages:
1. High speed and convenient switching between gears. Thanks to the electronic control unit and hydraulic mechanism, switching times are reduced to 150 milliseconds, which plays a significant role in professional motorsport. None of the classic transmissions, both mechanical and automatic, can boast of a more nimble gear change. In addition, with a sequential gearbox, you will not frantically try to get to the right speed, rushing with all the horsepower around the ring, when the high load and shaking with vibration interfere with keeping the car on the correct trajectory.

2. No loss of speed when switching.

3. Economical fuel consumption.
The last two points are more likely a consequence of the first, but we cannot but take this into account, giving the sequential checkpoint its due.

4. Ability to switch paddle shifters. Yes, this technology, so beloved by real racers, was discovered thanks to the sequential shifting mechanism.
By the way, gamers also love this mechanism. Some even undertake to develop such boxes themselves =)

The fifth advantage could be called the choice between two modes - automatic and manual gear shifting (the so-called sport mode). But this feature is typical for automatic transmissions. And since the sequential transmission can exist independently, we will leave this advantage to certain types of automatic transmissions.

Disadvantages:
Here we are talking not only about the loads that the gearbox of Formula 1 cars experiences on the race track, but also about the loads that the hydraulic mechanism can experience when incorrectly shifting on civilian cars. No matter how simple it is to change gears on a sequential gearbox, it must be done in a timely manner. The units of this transmission are quite sensitive and wear out quickly due to the design features. After all, the more complex the mechanism, the more likely it is to break.

2. High cost of maintenance. Actually, here you can also refer to the design features of the sequential gearbox, and without unnecessary comments.

Misconceptions and myths associated with sequential checkpoint

1. Sequential gearbox and robotic gearbox are one and the same.
This is by no means the case. Despite a similar operating principle, a robotic gearbox at least uses electric servos to shift between gears. And in the sequential gearbox - hydraulic.

2. Sequential and automatic transmission are inseparable.
Another misconception caused by the widespread use of automatic transmissions paired with "sport mode". However, it is worth remembering the gearboxes used in motorsport, and everything falls into place. A sequential gearbox can exist separately from an automatic transmission.

3. The sequential mechanism is installed only on race cars and other sports cars, together with a cam box.
Undoubtedly, the duo of these two technologies gives a huge advantage on the track, but for more than a decade, a sequential gearbox has been used on production cars intended for public roads.

Application of sequential gearbox

Nowadays, the sequential mechanism is widely used and even managed to become a classic for some motorcycles and cars. For example, this type of transmission is typical of an old motorcycle. But the more popular application of this technology became famous for the models of the SMG gearbox, installed on BMW cars since 1996.

SMG 1 and SMG 2 have been installed in the BMW 3 Series for a long time.
A moment of nostalgia or how it was:

1-Upshift indicator light; 2-Gear and program indicator;

3-Control lever; 4-; 5-Drive program switch (in the center console).

Main components first generation SMG shown in the figure:

1 SMG ECU; 2 ABS ECU; 3 Gear and program indicator (in the tachometer); 4 ECU of the indicator of the engaged gear and programs
5 Drive program switch (in the center console); 6 Control lever position indicator (center console); 7 Six-speed SMG gearbox with adjustment unit; 8 Shift Bracket SMG; 9 Drive pump; 10 Clutch slave cylinder; 11 Clutch; 12 Hydraulic block; 13 Master cylinder reservoir; 14 DME control unit*
The SMG is now in its third generation and has been installed on the BMW E60 M5 since 2005.

Reading 5 min.

Here it turns out that one rod is pulled up at the moment of switching, and the other is pressed. That is, at the moment of pulling up the first gear shift thrust, the second gear thrust is pressed. This made it possible to significantly reduce the time interval for switching in comparison with a conventional gearbox.

Translated from English, sequential is translated as a sequence. Therefore, a sequential gearbox only means sequential gear shifting. This principle of operation consists in influencing the control of the foot (an example is a motorcycle), for quick switching - a sports car; in the case of a large number of gears, the choice of which is not very convenient by shifting the lever - this is a tractor, trucks. Most often, shifting occurs due to the displacement of the control from the neutral position. While the principle of operation of a classic gearbox is an independent choice of gear.

Sequential box development

So many transmission boxes have not been created in the entire history of the automotive industry. So the creation of a sequential transmission did not pass by. Most often we hear, manual transmission or automatic, but it is worth understanding that this is not the end of the matter, as there are many more options for shifting gears.

There is a difference between these checkpoints that is worth understanding. Take, for example, a conventional car with a manual transmission. In this case, the driver independently chooses the speed transmission. That is, having accelerated, he has the opportunity to switch from third speed to fifth, or, on the contrary - when braking, go from fifth to third. This mechanism can also be called a search mechanism, since the inclusion of a gear transmission is completely dependent on the driver. Once again, I would like to note that the gear can be any, the most important thing is to match the driving mode and the loads on the car.

But as for the owners of a sequential gearbox, they are deprived of such a possibility of free switching. This action can be performed only one value, either up or down. That is, the switch will look like this: two-three-four or seven-six-five, which is typical for BMW motorcycles and M1-M motorcycles. It is impossible to achieve another switch on such a box.

Sports type M

More recently, a seven-speed sequential gearbox has been developed. This is the first model of the 7-speed SMG transmission in the global automotive industry. Thanks to its ultra-short shift times, combined with the power of the powertrain, it allows its owner to make their own choice of sporty or comfortable riding style.

Historical background

Such a box has already managed to become traditional for BMW cars. Already in 1996, SMG 1 began to be installed on the E36 M3 model. In 2001, the E46 M3 models were equipped with SMG 2. And already in 2005, the SMG 3 gearbox was installed on the E60 M5 model. What distinguishes this gearbox from previous models is a noticeable reduction in the time spent on gear shifting.

This third-generation transmission model is equipped with individual shift rods, which allows for a noticeable reduction in thrust at the time of shifting. How could this have happened?

How the switching process works

Comparing a conventional gearbox with a sequential SMG 3, you notice that in a conventional gearbox, at the moment of shifting, the gearshift rod is pulled up, then turned and pressed. In the compared device, everything happens differently. Here it turns out that one rod is pulled up at the moment of switching, and the other is pressed. That is, at the moment of pulling up the first gear shift thrust, the second gear thrust is pressed. This made it possible to significantly reduce the time interval for switching in comparison with a conventional gearbox.

Sequential gearbox operation

So, the familiar manual transmission has evolved and made it possible to come to a new type of transmission, which should make it easier for the driver to control the car. And such an important invention was the automatic transmission, which was modernized and improved. And today, it allows the driver not to think at all about what and when to switch the speed. But no one threw away the mechanical equipment either. She also continued to develop and now the result of this research was the sequential gearbox. The result of this transmission was the inclusion of speed in a strict sequence.

Principle of operation

This type of gearbox was developed on the basis of mechanics. The main difference between this transmission is that instead of helical gears, gears with straight teeth are installed here, and there is no clutch pedal (this role was taken over by the electronic control unit). Gear shifting in the box is carried out using a hydraulic mechanism, which leads to a significant reduction in gear shifting.

The installation of a gearbox with a sequential mechanism is especially common in racing cars. Realizing that such a sequential gearbox would be especially convenient for racing drivers, it means that it was necessary to perform such an installation on racing cars. This is due to the fact that high speed contributes to strong vibration of the car and in this case it is difficult for the driver to get into the required gear, while the sequential gearbox is able to cope with this task.

Advantages and disadvantages

This sequential transmission has its own characteristics. The advantages of this unit are the absence of a clutch pedal, which is especially convenient for novice drivers. The next positive quality that characterizes this model of the device is the speed of gear shifting, which exceeds the classic automatic and manual transmissions. Another advantage is economy, which is due to the reduced gear shifting. It also offers the ability to select a mode - mechanic or automatic.

The disadvantage of this device can be called its design. That is, this mechanism is not resistant to wear and tear and quickly breaks down under heavy load. An example is racing cars. After each ride, the sequential gearbox is most often subject to a mandatory bulkhead. In principle, if the operating rules are not followed, then the sequential gearbox can fail on serial cars, which means that it will entail expensive repairs.

In translation, sequensum means "sequence". A sequential gearbox can be considered a mechanical unit in which a separate device controls the clutch. That is, in a car equipped with the described gearbox, there will also be 2 pedals, as in a car with an automatic transmission, but the gears must be switched manually (in some cases, automatic switching is also possible).

Principle of operation

When you turn on the gear yourself and press the gas pedal, special sensors inform the electronic unit, which transmits a signal to the box. It also has sensors that transmit their signal about the speed of the car to the progressive block. The latter, in turn, makes adjustments to the speed limit, coordinating the work of the gearbox mechanisms. This takes into account the engine speed, the operation of the air conditioner and the readings on the instrument panel.

Gear shifting is carried out by means of servo drives (actuators), which are hydraulic on the sequential box. If electric, then such a gearbox is called robotic (in practice, a gearbox with both hydraulics and electric actuators is called robotic). The command to change gear is given by the driver in manual mode or using the on-board computer.

Features of sequential gearbox operation

The principles of operation are reminiscent of an automatic transmission, however, the sequential unit is characterized by the efficiency and reliability inherent in a manual transmission. Moreover, the "robot" is much cheaper than the "machine". The main feature of the sequential box is the ability to switch from low gear to high without losing speed, which invariably drops when using a mechanical unit. On a number of modern cars, the sequential box is controlled by buttons located on the steering wheel, which allows you to switch without taking your hands off the steering wheel.

Another plus for cars equipped with a "robot" is lower fuel consumption when compared with an automatic transmission. The lack of a third pedal helps beginners get up to speed faster, while experienced drivers can choose between manual and automatic gearshifts.

The disadvantage of robotic boxes is low wear resistance, which is especially pronounced under heavy loads or an aggressive driving method. Therefore, when operating this type of gearbox in manual mode, it is important to switch from one speed to another in time (you need to feel the moment). Otherwise, breakdowns are inevitable, and repairs "

Automotive engineering has made great strides over the past decades, as evidenced by new developments in transmission design. At the moment, on different models of both civilian and sports cars, you can find gearboxes of different types, which are designed to transmit large amounts of torque. Modern mechanical gearboxes differ from each other in design, and an example of this is the sequential gearboxes, which are widespread. It is worth noting that full-fledged sequential-type boxes remained unchanged only on motorcycles. Recently, however, automatic transmissions have become very popular, in which the option of manual gear selection is implemented. This function is called tiptronic or steptronic.

Sectional car gearbox

The main task of any transmission is to smoothly transfer power from the power plant to the drive wheels. By their design, gearboxes are divided into the following types:

1. Mechanical gearboxes. They are classified by the number of driving, driven and intermediate shafts, by the number of forward and reverse gears.
2. ... The main difference comes down to the design of the box.
3. Torque converter. The design is based on the Fourier planetary gear (planetary gear).
4. ... The design includes two pulleys that change their diameter under the action of centrifugal force, which entails a change in gear ratios. A chain or belt drive is located between the pulleys. The connection between the engine and the gearbox is carried out by means of a torque converter.
5. ... Manual gearbox with electronic control of the gear change process.

Above are some of the most common types of transmissions that are widely popularized in modern vehicles.
Modern mechanical transmissions consist of two or three shafts (depending on the type of drive: 2 - for front or rear, 3 - for rear and full), on which helical gears are installed. It is through the helical gearing that the torque is transmitted. Separators are installed between the gears, which include the gear selection forks. On the inner side of the separators and helical gears, a larger number of teeth are cut, by means of which they mesh with each other. In mechanical boxes, the shafts are made from a single piece of metal and cannot be disassembled. In such a transmission, you can turn on the first gear, and then, for example, third and the car will continue to move. If you get under way on a slippery surface without any inter-axle and inter-wheel locks, then you can start from the fourth and the engine will not stall.

Sequential car gearbox

The difference between a sequential gearbox and a standard mechanical gearbox is that such gearboxes are only two-shaft, all the gears in them are only spur and there are no synchronizers. Their role is played by movable couplings, which include gears. In addition to design differences, there are also operational differences: in a manual gearbox, the gear is turned on after the clutch is disengaged (experienced drivers change gears by selecting the required rpm and without the clutch), and in the sequential gearbox, when driving in a straight line or uphill, gears can be switched without disengaging the clutch, which allows make their design. Also, the advantages of sequential gearbox include:

• smaller overall dimensions of the box body;
• the ability to transfer more torque;
• withstands variable loads;
• switching speed is 0.1-0.2 sec;
• when changing gears, engine speed does not drop;
• power is not lost in the transmission, which is caused by heating of parts;
• ease of maintenance.

In a sequential box, when driving in a straight line or uphill, gears can be changed without disengaging the clutch.

It is worth noting that the principle of operation of a sequential gearbox is based only on sequential gear changes, both in reverse and in forward order. Thus, the gears are increased stepwise, i.e. you cannot jump, for example, from the second to the fourth, because the design of the box will prevent this. Also, one of the features of the sequential gearbox device is that the primary and secondary shafts in such a transmission are type-set, i.e. consists of several intermediate interconnected elements. This feature allows mechanics to quickly change gears on sports cars right during the races in order to choose the optimal gear ratio of the gear wheels for the current conditions of the competition.

Tiptronic gearbox

To realize the racing potential of their cars, Porsche has partnered with Volkswagen and auto parts manufacturer ZF Friedrichshafen to design automatic transmissions with manual shifting, but this is not a classic sequential transmission. This control principle received its own trademark and became known as Tiptronic. It is worth noting that this technology has been adopted by a large number of auto concerns, however, each representative of the world auto retail has adapted the tiptronic for their gearbox designs. In the automotive industry, this principle is called the steptronic. It should be noted that the imitation of gears in an automatic transmission is carried out by the gearbox control unit, i.e. there is no sequential mechanism in the design of the "automatic machine", because the box, which is already rather big in size, would reach dimensions comparable to the dimensions of the engine. That is why it is incorrect to call such boxes sequential!

What is the Difference Between Tiptronic and Automatic

Tiptronic shift lever

First of all, the difference lies in the mode of operation of the car. When the driver moves in automatic mode, he puts the gear selector in D mode and moves by pressing the gas pedal. At this moment, the engine control unit receives the signal from the accelerator position sensor and supplies more fuel to the engine cylinders, because the driver himself controls the throttle valve, which is designed to supply air to the same cylinders. Such actions lead to an increase in the speed of the crankshaft and, as a result, the speed of the turbine and rotor wheel of the torque converter increases, which causes a transition from lower to subsequent gears. As the engine speed and vehicle speed decrease, the transmission will downshift.

The difference between a tiptronic and an automatic machine lies in the mode of operation of the car.

When the selector is switched to S or M mode (tiptronic or steptronic), the driver independently selects the gear that will correspond to his driving mode. To do this, it focuses on the vehicle speed and the crankshaft speed. However, a protective function is implemented in each box, which consists in the fact that the tachometer needle never reaches the red zone or the so-called cutoff, because this will increase the load on the box. If you describe the difference in one phrase, then we can confidently say that the operation in the tiptronic mode and the automatic machine is identical, only the number of revolutions at which the gear changes are different. Now you understand how to use tiptronic on your car. It is worth noting that a slight shock to the body may be felt when downshifting. This does not indicate any breakdown, but only indicates that the driver has chosen the wrong speed mode for such a task.

Tiptronic box: pros and cons

The advantages of the box include:

• adaptation to any driving conditions;
• the ability to independently select gears;
• full implementation of the traction and dynamic potential of the motor;
• low or high gear of the Steptronic is automatically selected.

The disadvantages include:

• more complex firmware of the box unit;
• complex design of the transmission control lever;
• increased fuel consumption;
• complexity of management.

Any technically complex mechanism has both advantages and disadvantages.

And as the practice of operating gearboxes shows, the driver uses the tiptronic mode only 5-10% of the time. This trend begins to be seen already when buying a car. At this moment, the sales manager explains to the buyer how to drive the tiptronic, but often hears the answer that the driver does not need it.
On some European car models there are automatic adaptive sequential transmissions. Their main difference from the classic ones is that the adaptive "automatic" adapts to the manner of driving the driver and to the rhythm of movement. If you are driving a car at a low speed in the city, then such a transmission will quickly shift to an overdrive to achieve fuel efficiency. If you are driving on the highway, then the gear changes will be slightly delayed so that the car effectively picks up speed and quickly enters the driving mode in an increased gear.

What is isitronic box

Izitronic is a modification of robotic gearboxes that are installed on Opel cars. Such a gearbox consists of a mechanical part and a hydraulic control unit. There is no clutch pedal in the car's interior, but unlike other robots, such a box works exclusively on a sequential principle, because its design does not have D mode and there is no fixed P mode. The driver independently sends a control signal to the ICE control unit by moving the gear selector forward or backward.

Izitronic is a modification of robotic gearboxes.

Other examples of similar boxes include:

• SeleSpeed ​​- installed on Fiat, Lancia, Alfa-Romeo;
• - Volkswagen, Skoda;
• S-tronic (analogue DSG) - Audi;
• PowerShift - Volvo;
• DCT - Kia.

So which is better: tiptronic or automatic? It is impossible to unequivocally answer this question, since all answers will be exclusively subjective. We can say with confidence that each driver independently chooses the most optimal driving mode for himself.

As the situation on automotive forums shows, many motorists are very interested in the question of what a sequential gearbox is. We will immediately answer that it is often a manual transmission (although today automatic options are also increasingly common), the main feature of which is the ability to change gears only with a strict sequence up or down. Thanks to this, the driver does not have to think about which gear to activate - he simply increases or decreases it. But this type of gearbox has other features, so below we will take a closer look at what a sequential gearbox means.

We understand what a sequential checkpoint is and what are its features

So, the main feature of the sequential gearbox is the lack of the ability to freely select gears and jump over several at once. The need for such a gearbox arose due to the fact that the driver does not always have time to select the desired gear and brake to change it. By the way, such improved manual gearboxes are used not only on cars, but also on motor vehicles, where shifting between gears is often carried out with the foot.

If we are talking about sequential boxes installed on cars, then here they will be distinguished by the location of the control center. The lever (and sometimes even more comfortable and responsive buttons) for convenience is located on the steering wheel of the vehicle, while it will be necessarily marked with a special marking "S", which indicates the presence of a sequential gearbox on the car.

Important!On some cars with a sequential gearbox, gear shifting can be carried out not only manually, but also automatically.

This gearbox has three main modes of operation that can be activated in parallel with the main gears:

Standard mechanical.

Mechanical sports.

Auto when the driver does not need to change gears at all.

The last feature of the sequential gearbox is that when it is installed on a car, there is no need to install a clutch pedal. This not only makes driving easier, but also allows the engine to operate under standard conditions, independent of driving style and driver experience.

Where sequential automatic transmissions are used

Sequential automatic transmissions today can be found mainly on racing cars, since they are quite expensive pleasure, and in their intended purpose they are completely adapted for such types of cars. Thanks to such a gearbox, the driver is able to increase speed and change from gear to gear without the slightest slowdown, which is especially important for competitions. If, in addition, such a box will work on the basis of hydraulics, this will further increase the responsiveness of the car.

As for ordinary passenger cars, the sequential gearboxes installed on them are popularly referred to as the "manual" mode of operation of an automatic transmission. Nevertheless, even in this version, driving is considered lightweight and does not require the driver to accurately hit a specific gear. Among the serial cars on which such boxes were installed, it is worth mentioning:

BMW M3.

Mercedes Benz C-Class.

But in fact, sequential gearbox is more common than it might seem at first glance. As mentioned above, such gearboxes are installed on motorcycles, where there are usually only two gears. As for the neutral position of the gearbox, on motorcycles it is usually fixed between first and second gears. The sequential gearbox was even more widespread in the design and creation of agricultural tractors, on which a button or gear lever can be located both under the driver's feet and on the steering wheel. There are sequential gearboxes on heavy vehicles.

The device and principle of operation of the sequential gearbox

The basis of such a gearbox is the usual mechanical transmission, which has been improved and equipped with spur gears instead of helical gears. A significant structural difference of the sequential gearbox is the absence of a clutch pedal, which is compensated by the installation of an electronic control unit (it is also responsible for gear shifting in the automatic gearbox operation mode).

Thanks to the hydraulic mechanism, gear changes are as fast as possible and do not require precision as in conventional gearboxes. All that is required of the driver while driving with such a gearbox is an assessment of the complexity of the road and the load that is transferred to the car engine. To make his job easier, it is worth gradually increasing the gear. If low speed maneuvering is required, the gears are downshifted based on vehicle behavior and engine response.

Sequential or cam gearboxes?

It is also worth mentioning the existence of cam gearboxes, which in their design features have much in common with sequential gearboxes. In particular, they are united by the presence of spur and long gears with end lugs (to which the cams cling), thanks to which such gearboxes allow you to switch from one gear to another as quickly as possible without reducing the speed of movement.

However, it is almost impossible to determine which gearbox is better. For this reason, the designers simply combined them into one mechanism, which is already used today on racing cars that take part in Formula 1. So it is more correct to call a cam gearbox a good alternative to a sequential gearbox.

The advantages of using such a box on cars and other types of transport

We have already figured out what a sequential checkpoint is. However, let's summarize all the advantages of using such a gearbox in different modes of transport:

1. No clutch pedal. This feature is most relevant for those who are just learning to drive and can confuse the pedals. In addition, the lack of grip makes it easier to control the car in difficult racing conditions, when it is important for the driver to concentrate not on the pressure on the pedal, but on the track.

2. Gears change as quickly as possible. In this, no other type of gearbox can compare with sequential gearboxes. This advantage also includes the fact that when the gear lever is pressed up or down, the driver does not have to think about which gear to shift the lever to. He just raises or downgrades them.

3. Automotive designers also note that the lack of deceleration when shifting from one gear to another also has a positive effect on fuel economy.

4. Work in two modes - automation and mechanics. Despite the fact that the designers have already simplified the process of driving a car with a mechanical sequential gearbox by transferring the buttons to the steering wheel, in some situations the driver may refuse to control the transmission altogether and entrust this task exclusively to the electronic control unit.

Disadvantages of sequential checkpoint

The sequential gearbox is not devoid of a number of disadvantages, and they are mainly associated with the design of such a gearbox. The first thing to think about when buying a car with such a transmission is accelerated wear on the transmission. Do not forget that in extreme and too harsh operating conditions, the hydraulic mechanism wears out quickly and can fail at a very inopportune moment. For this reason, racing cars have to be completely revised and replaced literally after every race.

It was also mentioned above that, thanks to the installation of sequential gearboxes on serial cars, their power is significantly increased. But there is also a pitfall here: this can only be achieved if you switch from lower to higher gears and vice versa correctly and on time. If the driver does not feel well his car and its needs, this again can lead to failure of all elements of the hydraulic transmission. At the same time, the restoration of such a system will cost the car owner very expensive.

In this regard, it is recommended to get behind the wheel of a car with a sequential gearbox only for experienced drivers who have driven their way both on a manual gearbox and on an automatic. Lack of experience in driving a car can negatively affect its condition.

Based on the foregoing, it is rather difficult to determine the rationality of buying a car or installing a sequential gearbox on it. Although in general it provides a number of advantages, not all drivers need it. And it's not so easy to change from the usual gearbox with a lever to the right of the driver's seat.
