Automated Manual Transmission (AMT) And Its Difference From Automatic Transmission (AT)

not everyone clearly understands the difference between them and why people choose one of these two types of transmission. The following article will help you clearly distinguish the difference between semi-automatic transmission and automatic transmission.

1. What is automatic transmission (AT)?

Automatic Transmission (AT) is a type of transmission that can automatically change gears without driver intervention. Widely used in popular cars, luxury cars, and even sports cars, AT transmission makes driving easier, especially in heavy traffic conditions.

Advantages of automatic transmission (AT):

Convenient: The driver does not need to intervene in gear shifting. Just move the gear lever in D (Drive) mode, the vehicle will automatically change gears according to the speed and load of the engine.
Safe and easy to use:AT gearbox helps reduce stress for the driver, especially on long trips or when driving in crowded, congested areas.
Smooth acceleration:AT gearbox can change gears without interrupting the transmission process, providing a smooth and comfortable driving experience.

Disadvantages of automatic transmission (AT):

More fuel consumption: Compared to other types of transmissions, AT transmissions can consume more fuel because they use a complex torque converter and control components.
High maintenance costs: Automatic transmissions have complex structures, so maintenance and repair costs are often higher than manual transmissions.

2. What is an automatic transmission (AMT)?

The semi-automatic transmission (Automated Manual Transmission - AMT) is essentially a manual transmission (MT) but with the intervention of an automatic system to help the driver change gears without having to use the clutch pedal. The AMT system automatically controls the gear changes, but the driver can still take the initiative when necessary, through manual gear shifting modes (tiptronic).

Advantages of semi-automatic transmission (AMT):

More fuel efficient: Since it is essentially a manual transmission, AMT is more fuel efficient than a traditional automatic transmission.
Reduce maintenance costs: AMT gearbox has a simpler structure than AT gearbox, so maintenance and repair costs are lower.
Sporty driving feel: The driver can actively change gears, creating a sporty and flexible driving feel, especially in situations of overtaking or rapid acceleration.

Disadvantages of semi-automatic transmission (AMT):

Gear shifting feels not smooth: Because it uses automatic gear shifting technology, sometimes the driver will feel that the AMT gearbox changes gears jerkily, not as smoothly as the AT gearbox.
Not suitable for driving in congested traffic: When having to stop and start continuously, the AMT gearbox may not be as flexible as the AT gearbox, causing discomfort to the driver.

3. Difference between semi-automatic transmission and automatic transmission

Here are the major differences between automatic transmission (AT) and semi-automatic transmission (AMT):

a. Operating principle:

Automatic transmission (AT): Uses a fully automatic transmission system without driver intervention. Gears are shifted automatically when the vehicle changes speed or load.
Semi-automatic transmission (AMT): Essentially a manual transmission, but equipped with an automatic system that allows the driver to shift gears without using the clutch pedal.

b. Fuel economy:

AT gearbox: Consumes more fuel because the system has a complex structure and the movement of the transmission parts is not optimal.
AMT gearbox: More fuel efficient thanks to the same operating principle as a manual transmission, providing better transmission efficiency.

c. Driving feel:

AT gearbox: Provides a smooth, comfortable driving experience, especially when moving in crowded areas.
AMT gearbox: Provides a sporty driving feel, but sometimes there is a jerkiness when shifting gears, especially in slow driving situations.

d. Maintenance costs:

AT gearbox: Maintenance and repair costs are often higher due to complex construction.
AMT gearbox: Lower maintenance costs due to simple construction, easy maintenance and repair.

4. Which gearbox should I choose?

Choosing the right transmission depends on the needs and preferences of the driver. If you need a car that is easy to drive, smooth and not too concerned about fuel costs, an automatic transmission (AT) will be the ideal choice. However, if you want to save fuel and maintenance costs and love the feeling of sporty driving, an automatic transmission (AMT) will be an option worth considering.

Advice: Before choosing, you should carefully consider how to use the vehicle in traffic conditions, because each type of gearbox has its own advantages and disadvantages depending on your intended use.

Conclude:

Both automatic and semi-automatic transmissions have their own advantages. Understanding the differences between them will help you make the right decision when choosing a vehicle.
