Does CVT mean automatic transmission?

CVT stands for automatic transmission. Here is an introduction about CVT: 1. Introduction: CVT represents the vehicle's transmission, specifically a continuously variable transmission. The difference between this type of transmission and other automatic transmissions is that the gear ratio is not intermittent but continuous, making it one of many transmission types. 2. Types: The first type is the AT transmission, known as the hydraulic automatic transmission, which was an early form of automatic transmission and is still used in some models today. The second type is the CVT transmission, a mechanical continuously variable automatic transmission, commonly used in Japanese models. The third type is the AMT transmission, an early form of transmission. The fourth type is the dual-clutch transmission, which features two sets of clutches and was first adopted by German vehicles.
I've noticed many friends think CVT is synonymous with automatic transmission. In fact, it stands for Continuously Variable Transmission, which is essentially an advanced form of automatic transmission but operates on a different principle. Traditional automatics change gears using planetary gear sets with fixed ratios, while CVT employs a pulley and steel belt system to continuously and seamlessly adjust the gear ratio, eliminating any shift shock and delivering smoother acceleration. This design allows the engine to stay within its optimal RPM range, not only improving fuel efficiency—typically 10% to 15% more economical than conventional automatics—but also making it ideal for frequent stop-and-go city driving. However, CVTs have drawbacks too, such as potentially louder engine noise and less robust power delivery during hill climbs or sudden acceleration. Improper maintenance can also lead to steel belt wear, resulting in higher repair costs. Overall, CVT falls under the automatic transmission category because it enables automatic gear shifting without manual intervention, with technical differences stemming from the pursuit of greater efficiency and comfort.
I have to share my actual experience driving a CVT car. A few years ago, I bought a Japanese car with a CVT transmission. Indeed, the 4S store salespeople all referred to it as an automatic transmission. Starting and driving are entirely controlled by the computer for shifting, with no gear lever to push around, which is super convenient for lazy people like me. The driving feels incredibly smooth, and on the highway, you can barely hear any gear shifting sounds. The average fuel consumption is just 7 liters per 100 kilometers, significantly more fuel-efficient than my friend's traditional automatic transmission. However, once when climbing a mountain road, the engine buzzed loudly, and the speed increase was a bit slow, but overall, it didn't affect the convenience. I think CVT is a smart upgrade to the automatic transmission, especially suitable for daily commuting and family cars. Just remember to change the specialized oil regularly—don't be like me in the first year, forgetting maintenance and almost running into problems.
