Why does Volkswagen like to use dual clutch in China, but AT gearbox in the United States?

Friends who like cars have generally heard of powershift. Because of the high shift efficiency, power shift is widely used in family cars by major automobile manufacturers. But at the same time, with the increasing application of major automobile manufacturers, various problems in the use of powershift are gradually exposed, such as high failure rate, easy to cause body jitter after long-term use and so on. Volkswagen is the first domestic automobile manufacturer to use powershift and the first joint venture brand to enter the China market. Many riders first heard that powershift is Volkswagen's DSG transmission, and it is also Volkswagen's worst transmission, which was directly exposed by CCTV. But in America, Volkswagen doesn't use DSG transmission. Why? Therefore, the reasons why Volkswagen uses DSG powershift in China and AT automatic transmission in the United States are different: some people say that they are experimenting in the domestic market, while others say that they attach importance to the domestic market. On this topic, in fact, you can simply analyze it.

First of all, let's talk about why people are paranoid about R&D in Power Transfer. Volkswagen will use Aisin's AT transmission in the early days, but it is difficult to get rid of the problem that patents are "subject to people". Therefore, in order to reduce the cost of building a car and not be "stuck" by others, Volkswagen is determined to develop powershift. Then someone will ask: Why doesn't Volkswagen learn AT and CVT transmissions? That's because the related patents are too protected and the operation is too difficult, so I gave up; Power shift had a large operating space at that time, so Volkswagen chose power shift.

In fact, powershift was first used in racing cars. Its advantages are fast shifting speed, light weight and impact resistance. However, unlike the daily roads, the track will not be congested, and even if the power shift is hot and frustrated, the performance will not be obvious, so it will not attract attention. However, when applied to civilian cars, there will be problems such as overheating and frustration, which will be amplified under complex road conditions. Although Volkswagen has been in public relations with powershift, the problems caused by the structure of the transmission itself can only be improved and cannot be completely solved. Especially the dry double clutch is more obvious, and the wet double clutch lubricates and cools the oil more, so the use experience will be slightly better.

Then why did Volkswagen take the lead in using powershift in China? It can be said that Volkswagen is almost one of the car brands that most people prefer in joint venture vehicles, and Volkswagen really attaches great importance to the China market for many reasons, so I won't elaborate here. Because most people trust and recognize popular technology, the public dares to take the lead in using powershift in China. To a large extent, it can be said that the public is "doing whatever they want", which satisfies some consumers' yearning for advanced technology and also establishes technical barriers for independent brands. However, the Volkswagen DSG transmission model has not been used in other countries before entering the China market. "China debut" can be said to be a "bet" between Volkswagen and the domestic market, so some people say that Volkswagen's experiment with domestic consumers is actually well-founded. However, the final result is not satisfactory. Due to the prominent DSG power shift problem, the public reputation has also been affected, which means "shooting yourself in the foot".
