When you buy a car or visit the Internet, you will first pay attention to the brand, appearance, price, gearbox and fuel consumption. Today I'll talk about the gearbox. MT, AMT, at, CVT and DSG are common. What's the difference?

In general, novices will be confused about whether to buy at or MT (automatic gear, manual gear), followed by the well-known DSG (double clutch gearbox) on the market with many types of gearbox, each with its own advantages and disadvantages.

Next, we will introduce the knowledge of gearbox.

MT: the abbreviation of manual transmission, also known as mechanical transmission, requires manual control of the gear handle to control the gear engagement position in the gearbox, so as to achieve the purpose of transmission.

Advantages: relatively simple structure, reliable performance, high driving pleasure, high transmission efficiency.

Disadvantages: it's troublesome to operate. There will be obvious setbacks when switching. When driving in the city, it's quite tired when there's congestion or traffic jam.

At: the abbreviation of automatic transmission, also known as automatic gear. Compared with manual gear, the structure of automatic gear is relatively complex. It is composed of hydraulic torque converter, planetary gear and hydraulic control system, without clutch. It has the function of automatic transmission, which makes it easier for the driver to get on hand, which is better than the manual gear, but the manual gear is more sensitive than the automatic gear.

CVT: short for continuous variable transmission. CVT has no specific gear, which is similar to automatic transmission in operation, but the change of transmission ratio is different from the trip process of automatic transmission. It will not break point but continuous, so it is more continuous and smooth in power transmission. The fuel economy of CVT is better than that of automatic transmission.

DSG: short for direct shift gearbox. Also known as double clutch transmission. It is characterized by faster shifting speed, greater transmission torque and more efficient power than other transmissions. Direct shifting transmission is the most advanced transmission system in the world.

Each of these transmissions has its own advantages, but the final choice depends on the actual needs of the driver and the economic capacity. The driving environment has been comprehensively considered.
