What is the difference between AMT and AT in cars?
2 Answers
The differences between AMT and AT in cars: 1. Different structures: The AMT transmission is composed of a manual transmission clutch with an added microcomputer-controlled automatic shifting system; the AT transmission requires a connection to a torque converter and consists of a clutch, hydraulic automatic shifting, and an oil pump. 2. Different functions: The AMT transmission achieves gear shifting through automatic operation by a microcomputer control system; the AT transmission does not require a clutch for shifting, and the power connection during shifting is smoother. 3. Different efficiencies: The AMT is a mechanical automatic transmission with less power loss and no resistance from oil; the AT transmission requires a torque converter for power transmission, and its components operate immersed in oil, which creates some resistance, resulting in power transmission losses.
After driving several cars with different transmissions, the AMT feels like a manual with an automatic function—it uses an electric motor to control the clutch and gear shifts, but it often has jerky movements, like the car lurching during acceleration. It’s less tiring than a manual, but not exactly comfortable. The AT, on the other hand, is completely different. It has a torque converter inside, making gear shifts as smooth as cutting butter, whether in traffic or on the highway, providing a much more stable and reassuring drive. The AMT’s advantage is its affordability and fuel efficiency, but its jerky performance in stop-and-go city traffic can be frustrating. The AT is more expensive but offers a better experience. I recommend test-driving both to compare—you’ll quickly notice that the AMT suits tight budgets or smooth road conditions, while the AT is the top choice for comfort.
