The S tronic combines the practicality of a contemporary automatic transmission with the effectiveness and sportiness of a traditional manual gearbox. Rapid shifting is possible with almost no audible interruption of the power flow thanks to the dual-clutch transmission. Dynamically and smoothly, the car accelerates.
Two multi-plate clutches and two sub-transmissions make up the 7-speed S tronic. Although both of these are constantly in use, only one of them is ever being powered by the engine. For instance, the second transmission section is already in fourth gear while the driver accelerates in third gear. By switching the clutches, one opens and the other closes, shifting the gears is accomplished. It just takes a few hundredths of a second to switch gears, with hardly any loss of power. The car passes by so swiftly and smoothly that the driver hardly notices it.
The two unique oil systems of the 7-speed S tronic are one of its distinguishing qualities. Gear sets, the center differential, and the front-axle differential are all lubricated independently, while the dual clutch, mechatronics module, and oil pump are all supplied by their own oil circuits. The benefit of this is that there is no need to compromise on the lubricant being used, ensuring a sufficient amount of oil for all components.
S tronic combines the practicality of a modern automatic transmission with the effectiveness and sportiness of a traditional manual transmission.
With the 7-speed S tronic, the driver has the option of manually shifting gears or letting the transmission do it for them. In manual mode, he chooses when to shift gear and does so by pulling the selector lever or using the paddles on the steering wheel. With the Drive program (D) and Sport program, he can alter the way the transmission behaves when shifting gears in automatic mode (S). The efficiency mode can also be chosen in conjunction with Audi drive choose, which is available for various models. This has a modified shift schedule and an energy-saving default configuration. When efficiency mode is engaged, for instance, the car automatically enters coasting mode and keeps moving without any engine braking losses if the driver lifts their foot off the accelerator.
While we put a lot of emphasis on dynamic performance, we also place a high value on efficiency because high efficiency lowers fuel consumption and pollutant emissions.

How effective is Audi S Tronic?
It makes sense to equip your new Audi with S Tronic transmission if you value top performance and smooth highway cruising.
When you consider your car’s better performance and decreased fuel consumption, the modest price premium over a conventional manual or automatic gearbox is pretty negligible.
Is there a possibility that something could go wrong with all the sophisticated technology and high-tech components? The S Tronic gearbox is dependably dependable when maintained, which is good given the high maintenance expenses. Visit our site on Audi Reliability to learn more if you’re interested.

Audi S tronic transmissions are produced by whom?
A new seven-speed S tronic transmission from Audi will be available. The new twin-clutch transmission has a 550 Nm torque capacity and is made to function with longitudinally installed engines and the quattro all-wheel drive system. In series production this year, Audi will add the new S tronic to several vehicle lines.
The new transmission, which was wholly created by Audi, was created for the mid-range model lines and is intended to be both sporty and economical.
The new seven-speed S tronic from Audi has several modes of operation. The D (Drive) and S (Sport) programs are still available in the fully automatic mode, in which the computer chooses the gear. With the shift selector lever or the optional rocker switch on the steering wheel, you can manually change the gears as well.
Two transmission mechanisms make up the seven-speed S tronic. Two multidisk clutches that regulate various gears are integrated into it. For the odd gears 1, 3, and 5, the big K1 clutch on the outside transmits the torque to the gear wheels using a solid shaft. They are situated toward the middle of the car, at the back of the cast-aluminum transmission case.

Around the solid shaft rotates a hollow shaft. It is attached to the smaller K2 clutch, which controls the gear wheels for the even gears 2, 4, and 6, as well as reverse gear, and is built into the interior of its larger sibling. On both driving shafts, there is a single row of gear wheels in the following positions: 4, 6, 2, R, 1, 3, 7, and 5.
Even though both transmission structures are constantly in use, only one is being driven by the engine at any given moment.
The quattro drivetrain’s self-locking center differential receives power from the drive shaft and distributes it in two directions. In the fundamental distribution, 40% of the torque travels over a side shaft to the bevel gear of the front-axle differential, and 60% of the torque travels over the cardan shaft to the differential for the rear axle. This shaft uses a slanted, beveloid gear since it is mounted at an angle of 7.2 degrees. It is hollow as well, reducing weight.
Sporty and agile driving characteristics are provided by the asymmetric-dynamic power distribution, which places a modest focus on the rear end. The center differential has a maximum power transfer capacity of 65 percent to the front axle and a maximum power transfer capacity of 85 percent to the rear axle.
One of the most significant development objectives was the extremely accurate handling of both multidisk clutches. This was made possible in part by the employment of an efficient coil spring package, an electronically controlled rotation speed adjustment, and a compact pressure cylinder. Maximum comfort and precision are provided during startup and shifting by this technology package.
The mechatronic module controls the transmission. When facing the direction of travel, this module is incorporated on the left of the transmission and consists of a small set of control units and hydraulic control valves. Its control strategy enables extremely fine management of the power required for the process as well as variable speed control of the gear shifting process.
An effectively running oil pump that is situated next to the mechatronic module and is powered by a gear section supplies the necessary control pressure. A vacuum booster supports the oil pump in order to cool the double clutch while startup. As a result, it is possible to roughly double the volume of oil pumped when necessary without adding power.
The two unique oil systems of the seven-speed S tronic are one of its distinguishing qualities. While the dual clutch, mechatronic module, and oil pump each receive seven liters of automatic transmission fluid (ATF) oil through their own oil circuit, the wheelsets, central differential, and front-axle differential each receive around 4.5 liters of hypoid gear oil for lubrication. Due to the separation, the development engineers could place each component in the appropriate location without having to make compromises due to the use of a single lubricant.
A sporty, short transmission ratio for the first gear and a lengthy, rpm-decreasing ratio for the last gear are both conceivable with the maximum transmission-ratio spread of 8.0:1.
How trustworthy are Audi automatic transmissions?
I have the chance to purchase my 2014 Audi A3 corporate vehicle, which I have had since new and has only 39,000 miles on it. I’m trying to decide if it’s a smart idea or not because I’m scheduled to retire next year.
However, I’ve been informed that many vehicles, including mine, with DSG dual-clutch automatic gearboxes reach the five-plus-year mark with major issues that frequently need replacing the entire gearbox. My car wouldn’t be a decent purchase after this. Please let me know if DSG gearbox issues are frequent.
What Car? says…
The current Audi A3 is a highly reliable vehicle, scoring 96.8% for gasoline versions and 96.6 percent for diesel models in our most recent reliability survey. Only 1% of owners reported gearbox problems. 15 percent of owners of the prior generation (20032013) A3 reported gearbox issues, suggesting that these issues are more prevalent. Your vehicle is the most recent model, thus there shouldn’t be a problem.
What does the sport mode on an Audi do?
The steering is made more rigid. Sport mode typically toggles on the ability to adjust the steering feel when using electric power steering. To make the steering seem livelier and heavier, the sport mode will increase the resistance.
What is included in the S line package?
The trim package known as Audi S line gives many Audi automobiles a sportier flair. Not to be confused with Audi’s high performance S models (like the S4 or S6), the S line trim (like the A4 S line or A6 S line) mostly focuses on suspension and aesthetic changes rather than improving engine performance.
A flat bottom or sport style steering wheel, paddle shifters, aluminum trim, a black headliner, and S line seats are among the features seen in the majority of S line packages. Audi Drive Select, which enables you to modify the vehicle’s suspension dynamics or a sport suspension, is frequently included with the S line package. The kit is completed by distinctive exteriors, bumpers, and badging.
Are there paddle shifts on the Audi S tronic?
I’ll admit, I’ve never been a particularly good paddler. I’m ashamed to say that I can’t swim because I fell into the deep end of a pool when I was younger. Additionally, I feel uneasy in boats like rowing boats because of my inherent mistrust of the water.
But I’m happy to announce that, thanks to our new long-term Audi TT, my paddling has suddenly gotten considerably better. And what’s this? Not even getting wet is necessary. Instead, the TT’s paddleshift gearbox is all about injecting a dash of adrenaline into regular driving.
The S tronic transmission from Audi can be used in clutchless shifting mode, fully automatic mode, or both. The paddle shifters are located on the back of the multi-function steering wheel.
I’ve changed the way I drive to use both because there are moments when it can be challenging to find the paddles, which are linked to the wheel rather than the steering column.
And what a difference the system makes in the TT’s dynamism. The supercoup feels more like a super heavyweight when it is in automatic mode since it continuously wants to shift up to sixth gear, which makes it slow, plodding, and unresponsive. The Audi comes alive when you shift to manual mode, enabling you to fully utilize the magnificent 3.2-liter V6 engine. Although there is always a tiny delay as the TT changes, acceleration is quick and gradual. And that latency is the biggest complaint about a machine that is exquisitely designed, developed, and assembled.
Even though more modern TTs are now hitting the roads, the clean lines outside still draw admiring glances. The interior’s grey leather trim is holding up considerably better than I anticipated, and despite having driven almost 10,000 miles, the entire vehicle still feels taut and sharp.
I am aware that my road test coworkers think that the BMW 3-Series coupe still outperforms the TT dynamically. However, the essential issue is what you hope to gain from your coup. You can’t ask for more than that since every time I drive the Audi, it’s a great occasion in my eyes.
