There is no doubt that a car’s transmission is critical to not merely its operation but also its performance. A shining example of a transmission that performs its duties wonderfully well is the S tronic automatic transmission. It brings together the athletic properties of a manual gearbox with the benefits of an automatic. But how does it work? It includes two sub-units and combines two multi-plate clutches that control the various gears. The large K1 clutch, located on the outside, directs the torque to the gear wheels for the odd-numbered gears (1, 3, 5, and 7) by the means of a solid shaft. A hollow shaft rotates around the solid shaft. It is connected to the smaller K2 clutch, which is integrated into the inside of the K1 clutch, and controls the gear wheels for the even-numbered gears (2, 4, and 6) and the reverse gear. Though both these structures are continuously active, only one of them is connected to the engine at a given time. So say when the driver accelerates in third gear, the fourth gear is already engaged in the second transmission structure. The shifting of gears takes place as the clutch changes and takes only a few hundredths of a second. In fact, the shifting of gears is executed with nearly no interruption to the flow of power and is hardly detected by the driver.
The compact and sturdy mechatronics structure consists of the electronics along with the hydraulic control elements. The system’s control concept allows it to not only regulate the speed of the gearshift process but also to accurately modulate the requisite power. Additionally, the multi-plate clutches are handled with utmost accuracy that allows the S tronic to be responsive even in stop-and-go traffic and while steering. Though offered in several variations, all forms of the S tronic automatic transmission offer a variety of benefits including high efficiency, intelligent management, and a large gear-ratio spread with very wide top gears. Hence, in comparison to a manual gearbox, the Audi S tronic transmission often delivers lower fuel consumption.
Interestingly, the ultra-compact seven-speed S tronic offered on the Audi A3 weighs just about 70 kilograms. Its two dry clutches do not require a separate oil supply, thus further enhancing the car’s efficiency. One must also note that all variations of the S tronic can be combined with the Audi’s start-stop system. But that’s not all – the seven-speed S tronic can be used in a number of ways on a variety of models. The automatic mode offers two programs, namely, Drive (D) and Sport (S). The driver can control the gear shifting via the selector lever or with the shift paddles behind the steering wheel depending on the provisions of the model in question. Another advantage of Audi’s many high-performance cars is the launch control system that makes complete use of the car’s acceleration potential. In fact, the seven-speed S tronic transmission for longitudinal engines can handle engine speeds of up to 9,000 rpm.
