The domestic research on the three major parts lags far behind overseas car companies, and the development of the gearbox is not the first. As early as 2011, BYD Swift has been equipped with a self-developed dry dual clutch gearbox 6DT25. , And in the later launch of the s7 took the lead in carrying a self-developed wet dual clutch gearbox 6DT35. Great Wall Self-developed 7DCT450 Wet Dual Clutch Gearbox is not too bad in terms of parameters. The maximum torque of 450 Nm·m is higher than most of its own brands nowadays, but no speed limit is also displayed on the side of the Great Wall 2.0. t The engine's low torque is really weak, and it can only rely on the deceleration and increase the torque to ensure a certain torque output. Does this 7DCT gearbox have reached the top level of the current joint venture brand? Or look at the actual application.

According to the organizers, the selection criteria can be attributed to three points: gearboxes with great influence on the industry, market and consumers, high attention and importance, and outstanding performance in the comprehensive evaluation of “advanced gearboxes”. Outstanding performance in the same type of opponents; transmission with special performance and special performance.
