Which is better, 8at gearbox or 7-speed dual clutch?

Both the 8at gearbox and the 7-speed dual-clutch gearbox are relatively common. These two gearboxes have their own advantages and disadvantages. It is impossible to determine which gearbox will be better. The owner needs to choose the appropriate transmission according to the usage conditions. box.

In daily driving, the 7-speed dual-clutch gearbox will be more fuel-efficient. Due to the faster shift speed and less power loss, it will be more fuel-efficient, but the vibration will be more serious, and there will be a large setback . The shifting of the 8AT gearbox will be relatively smooth and comfortable without obvious frustration, but the disadvantage is that it has higher fuel consumption.

Advantages and disadvantages of 7-speed dual-clutch

1. The structure is similar to the combination of two manual gearboxes. These two clutch gearboxes can control odd gears and even gears respectively, so they have high shifting efficiency and transmission efficiency;

2. The dual-clutch is equipped with both a wet clutch and a dry clutch. When using a dry clutch, the range of power transmission will be limited to a certain extent, and it cannot carry a large torque output, otherwise the temperature of the clutch will be too high. When using a wet clutch, the working state of the gearbox will be unstable when driving on urban roads.

The 8AT gearbox will be more suitable for driving on urban roads, which often have to start and stop and drive at low speeds, so it will be more comfortable when facing urban roads. If the vehicle often runs at high speed, it is better to use a 7-speed dual-clutch gearbox, which will have lower fuel consumption and is less prone to failure.
