6AT is more durable.
Let’s look at the transmission efficiency first. Except that Mazda’s 6AT gearbox can barely compete with the 7-speed dual-clutch gearbox, Aisin’s 6AT gearbox is less efficient than most 7-speed dual-clutch gearboxes. There is still a big gap in transmission efficiency, such as gear shifting enthusiasm, etc. The advantages of Aisin 6AT are in terms of comfort and fuel economy;
Looking at the driving experience, the advantages of the 7-speed dual-clutch gearbox It shifts gears quickly and accelerates fiercely, especially when overtaking, so it is still very exciting to drive. The disadvantage is that most 7-speed dual-clutch models will have obvious frustration in low gears, and the comfort will be worse; 6AT The performance is the opposite. Although the gear shifting is not as fast as the dual-clutch gearbox, the comfort is good enough. It can be regarded as a middle point between the dual-clutch and CVT gearboxes.
The last thing is reliability. From the perspective of failure rate and stability, the battle-tested 6AT gearbox is still stronger than the 7-speed dual-clutch, but the gap will become smaller and smaller.
The birth of 6AT has filled the domestic gap
In terms of automatic transmissions, the domestic 6AT market is basically dominated by imported brands such as Japan’s Aisin and Germany’s ZF. Although independent brand car companies The car was well built, but it was often hampered by various issues with the transmission. Dongan Automobile Development Co., Ltd. saw this opportunity and decided to create a 6AT transmission of our own.
With many years of experience in the production of Mitsubishi 4AT transmissions, Dongan Automobile spent 6 years and invested nearly 1.8 billion yuan to create a 6AT transmission with completely independent intellectual property rights, filling the gap in the domestic 6AT transmission.
This 6AT product is developed using the internationally advanced V-shaped development process and complete design specifications. Through power flow design analysis, CAE dynamic simulation, life and static strength analysis, and speed ratio spectrum design , gears, clutches, valve bodies, hydraulic systems, solenoid valves and other core parts design and various optimization work to ensure product design reliability.
