In fact, there are many dual-clutch gearboxes under 65438+ 10,000, especially domestic cars are basically dual-clutch, and Japanese are mostly CVT gearboxes. So why are there fewer models of 6AT gearboxes? The reason is that domestic cars have technical problems. The technology of 6AT gearbox is in the hands of Aisin Japan and ZF in Germany. If the AT gearbox is used, there may be a stuck problem. Once Volkswagen, once Guangzhou Automobile Chuanqi all encountered such problems.
If it is not Aisin gearbox, Volkswagen will not make up its mind to develop dual-clutch gearbox. If it doesn't want to be out of stock by others, it must master the core technology itself, whether it is a joint venture or a domestic one. The cost of independent research and development of AT gearbox by independent brands is doomed to be high, and the cost of purchasing core technology is too high, so that their own research and development can not bypass the patents of others. On the other hand, although the core technology of the dual-clutch gearbox is in the hands of Gertrak and Borgwarner, the dual-clutch technology is relatively simple and uncomplicated, and these two companies have no locking technology, so domestic brands choose the dual-clutch in the gearbox as the best choice.
Although Cavalier is also equipped with 6AT gearbox, this 6AT is not Aisin's 6AT, nor ZF's 6AT, but an AT gearbox independently developed by GM. This gearbox engine, code-named GF6, 1.0T, was also developed by GM itself. Of course, the price reduction of the Cavaliers is not a loss. As a car company, the main purpose is to make a profit, how can it sell cars at a loss?
Looking at Japanese A-class cars, you don't really need 6AT. Even Toyota doesn't have its own 6AT, mainly because CVT costs less. It's not that there are no domestic 6AT, such as Dongan 6AT and Shengrui 8AT, but there are still some gaps compared with the joint venture in transmission efficiency, stability and durability, so domestic cars are still mainly dual clutch. Independent brands have worked hard in the automobile industry in recent years and have improved in all aspects. The riding comfort of the dual clutch and the logic and reliability of shifting have also been greatly improved. It is said that it takes ten years to sharpen a sword, and so does the double clutch. In addition to high shift efficiency and good fuel economy, the current ride comfort is also very good.
Buying a car depends not only on the gearbox, but also on matching and driving experience. It is not that a good gearbox can bring a good driving experience. Different matching and adjustment will have different driving experiences. No matter what gearbox you are equipped with, you need a test drive to feel the real driving experience.
