What does AMT mean in cars?

The full name of AMT in cars is Automated Manual Transmission, also known as Sequential Transmission. It is an improved version based on traditional manual gear transmissions, combining the advantages of both AT and MT into an integrated electro-hydraulic automatic transmission. Specifically, it uses a manual transmission as the base and automates the operation of components originally controlled by human force, such as clutch disengagement and gear shift forks. The working principle of AMT is: determining the optimal gear, controlling the clutch disengagement and engagement, the gear lever's shifting, and the synchronous adjustment of the engine throttle opening, which were originally done manually by the driver, ultimately achieving automated control of the shifting process.
I've driven a car with an AMT transmission, which stands for Automated Manual Transmission. It drives like a manual but without a clutch pedal, so no worries about stalling in city traffic jams. It's cost-effective and fuel-efficient, used in many compact cars, like some economy models. In terms of driving feel, there's a slight jerk during take-off, and gear shifts are a bit slower when climbing hills, but you get used to it. I've discussed with friends—compared to the smoothness of a CVT, AMTs are simpler to maintain and have fewer faults, though comfort takes a slight hit. If you want to upgrade from a manual without spending much, it's a solid choice. Just keep up with transmission maintenance, and it'll serve you well for years.
As a car enthusiast, I've been studying AMT transmissions for quite some time. Its full name is Automated Manual Transmission, which essentially automates a manual transmission by using computer control for clutch operation and gear shifting, leaving you to just step on the accelerator. Its structure is similar to manual transmissions, featuring gear sets and electronic control systems, making it affordable and durable with lower fuel consumption than full automatics. It responds promptly on highways, but gear shifts can be inconsistent when decelerating into turns, resulting in a slightly inferior experience. This technology is commonly found in small cars, such as entry-level models from certain European brands. I recommend it for beginners to get the hang of driving quickly, but don't expect a smooth ride—it's not a high-end technology after all.
AMT has distinct features compared to other transmissions: its advantages lie in low cost and high efficiency, making gear shifts worry-free; the downside is less smooth driving with noticeable jerks. For example, on mountain roads, it may delay gear shifts, affecting comfort. CVT, on the other hand, is smoother but comes with higher full-automatic costs. AMT is simpler to maintain with lower part replacement costs, making it suitable for those on a tight budget. However, long-term use may lead to failures in batteries or electronic control components. If you prioritize practicality and saving money, choosing AMT is the right decision.
