Analysis on the types of automobile automatic gearbox: Who is better, AT, DCT or CVT?

First of all, it should be emphasized that the dual-clutch gearbox is divided into wet dual-clutch and dry dual-clutch. Volkswagen’s low-end models use 7-speed dry dual clutch, while the high-end models use wet dual clutch. Therefore, under certain circumstances, Volkswagen’s 7-speed dry dual clutch is still prone to problems, which also makes the dry dual clutch worse than CVT continuously variable gearbox in some cases.

1. Volkswagen’s 7-speed wet dual clutch shift is fast and stable.

Volkswagen models with 2.0T are mainly equipped with 7-speed wet dual-clutch gearboxes. This gearbox is obviously faster than the gearbox in shifting speed, and can accelerate faster under the same power, and it is also quite stable. There are no other disadvantages except a strong sense of low-speed shifting. Volkswagen’s 7-speed wet dual-clutch gearbox is also mounted on some models, so its performance can still be fully recognized.

2. The performance of Volkswagen 7-speed wet dual clutch gearbox is higher than that of CVT continuously variable gearbox.

As mentioned earlier, the stability order of automatic gearbox is AT>DCT>CVT, so we know that DCT dual clutch gearbox is better than CVT continuously variable gearbox. However, the dual clutch gearbox here refers to the wet dual clutch gearbox, not the dry dual clutch gearbox. Volkswagen’s 7-speed wet dual-clutch gearbox has good heat dissipation, faster shifting speed and greater endurance, which has obvious advantages over CVT continuously variable gearbox. However, CVT continuously variable gearbox can’t bear large torque, and it is easy to slip at high speed, so its performance can’t compete with wet dual clutch gearbox.

3. Volkswagen 7-speed dry dual clutch system is widely used in vehicles and has good feedback performance.

Whether Volkswagen’s 7-speed dual-clutch gearbox can be bought is mainly due to concerns about dry dual-clutch gearbox. Volkswagen mainly uses 7-speed dry dual-clutch gearbox on low-end models, such as,, and so on, which are popular models of Volkswagen. The 7-speed dry dual-clutch gearbox is used on these models, and the overall feedback performance is also good. Of course, Volkswagen’s 7-speed dry dual-clutch gearbox, its frequent shifting causes the gearbox temperature to rise, and occasionally the gearbox will stop shifting, which is also the reason why people are worried about whether the Volkswagen dual-clutch gearbox can be bought, but in reality this situation is still relatively rare.

Summary: Volkswagen’s 7-speed dual-clutch gearbox is well worth buying, especially Volkswagen’s wet dual-clutch gearbox, because it is used in Volkswagen’s mid-to high-end models. Volkswagen’s dry dual-clutch gearbox also performed well. There are still many models on the market that use Volkswagen’s 7-speed dry dual-clutch gearbox, and no major problems have been found yet.
