Everything you need to know about DCT vs DSG cars in India

Given the swift and effortless driving experience, millions of drivers prefer automatic transmission over manual gearboxes. As demand has picked up, many car makers are offering models with different kinds of automatic transmissions. The Dual-Clutch Transmission (DCT) also termed as Direct-Shift Gearbox Transmission (DSG), is a widely popular transmission system in current mainstream cars. What exactly is a Dual-Clutch transmission and how does it benefit us, let’s understand.

What is Dual-Clutch Transmission?

In order to understand the dual-clutch transmission, we first need to understand how regular manual transmission functions. The manual transmission works on the arrangement of three shafts, input shaft (crankshaft), countershaft, and output shaft (to the wheels). The engine rotates the input shaft which is connected to the countershaft through a clutch. The function of the clutch is to engage and disengage the input shaft and countershaft. The countershaft and output shaft have multiple gears mounted to them that remain meshed for different gear ratios. However, the difference is, the gears on the countershaft are rigidly joined with it and on the output shaft the gears are independent of the shaft. When you press the clutch pedal, the clutch disengages the input shaft from the countershaft, so that you can change the gear ratio, and when you remove your foot from the clutch pedal the input shaft again engages with the countershaft that then runs on the selected gear ratio. For a short while when the input shaft remains disengaged with the countershaft, the power is not supplied to the output shaft and this hinders the fuel efficiency.

While the operation of Dual-clutch transmission is much similar to that of the manual transmission, it works to minimize the time gap between switching gears. In the dual-clutch arrangement, two computerized clutches are placed concentrically and they don’t need any manual input. The input shaft/crankshaft remains connected to one clutch and ready to switch to another one. The countershaft consists of two concentric cylindrical shafts on the same axis, they are independent of one another and respectively connected to the two clutches. Both countershafts consist of gears that remain meshed with the independent gears on the output shaft at different gear ratios, just like the regular transmission. One countershaft is designed for even number gear ratios and another for the odd ones.

When the output shaft is running at a particular gear ratio, the computer is anticipating the next needed gear ratio and keeps it pre-selected for the switch, basing it upon acceleration, deacceleration, ongoing speed, and engine speed. So, if you are running the car at 3rd gear (odd number) through one clutch, the computer will keep ready either 4th gear or 6th gear for switching on the second clutch. The computer keeps switching the clutches, there is a bit of overlapping of clutches, but the whole process takes place so fast that there is almost no gap between the two speeds.

Advantages of the Dual-Clutch Transmission

  • In a manual transmission, the driver takes around half a second to switch gears and in DCT this process takes place in approx. 8 milliseconds.
  • DCT retains the advantages of manual transmission since their designs are much similar.
  • DCT reduces the time gap of switching between gear, this significantly improves the mileage of a car.
