MT, AT, CVT, hand-in-one, what’s the difference？

The so-called MT, AT and CVT all refer to the types of automobile transmissions. The transmissions in automobiles can be roughly divided into two categories: manual transmissions and automatic transmissions. Automatic transmission can be subdivided into hydro-mechanical automatic transmission (AT), continuously variable transmission (CVT), dual clutch transmission (DCT) and automatic clutch transmission (AMT). The so-called automatic manual transmission only adds a manual mode to the automatic transmission.

MT is the abbreviation of Manual Transmission. It is necessary to move the transmission lever by hand to change the gear engagement inside the transmission and change the transmission ratio. Its advantages are simple structure, low manufacturing cost and maintenance cost, high reliability, fuel saving and high transmission efficiency; The disadvantage is that the operation is more complicated, requiring higher driving skills and greater labor intensity.

AT is the abbreviation of hydraulic mechanical Automatic Transmission, which is what we often refer to as automatic transmission. Its advantages are simple operation, automatic speed change and torque change according to road conditions, effective avoidance of engine overspeed and overload work, high reliability and mature technology; Disadvantages are complex structure, high precision, troublesome maintenance, relatively low transmission efficiency, relatively high fuel consumption, and relatively high price of models equipped with AT gearbox.

CVT is the abbreviation of Continuous Variable Transmission, and its biggest feature is that it can realize the continuous stepless change of transmission ratio. Its main advantages are good driving comfort, enabling the engine to always work in the most economical speed range, good fuel economy and relatively simple structure; The disadvantage is that the transmission steel belt of CVT can bear limited torque, so it is not suitable for intense driving and extreme off-road, and the maintenance is difficult and the cost is high.

The so-called automatic manual transmission is not a type of transmission, but a manual mode is added to the automatic transmission, so that the driver can choose the gear independently according to the engine speed and speed, which can not only increase some driving pleasure, but also increase the power when driving on a slope and accelerating overtaking, making the car more maneuverable. All automatic transmissions can be made into automatic manual transmission, but its essence is automatic transmission.
