CVT is an automatic transmission. The introduction and working principle of automatic transmission are as follows: Introduction to automatic transmission: Automatic transmission eliminates the need for manual gear shifting while driving. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Common automatic transmission positions include P, R, N, D, S, and L. Currently, the most widely used automatic transmissions in the market include AT (automatic transmission), CVT (continuously variable transmission), DCT (dual-clutch transmission), and manual-automatic transmissions, each with its own advantages and disadvantages. Manufacturers choose different transmissions based on actual needs. Principle of automatic transmission: Power is transmitted through a chain system without actual gears, providing drivers with smooth driving experience and good fuel economy.

When delving into automotive transmission technology, CVT is definitely a form of automatic transmission. It is a continuously variable system that adjusts the gear ratio via a steel belt and pulleys, rather than the fixed gear sets of a traditional automatic transmission. This means there is no gear-shifting jerkiness during driving, and acceleration is extremely smooth, much like the feel of an electric vehicle. This makes it particularly suitable for city driving or novice drivers, as it simplifies operation—just step on the accelerator without the need for manual gear changes. Compared to traditional automatic transmissions (AT), CVTs typically improve fuel efficiency by around 10%, but may introduce slight high-speed noise or a lack of sporty feel. In summary, from a design perspective, it fully falls under the category of automatic transmissions and is a standard feature in many Japanese brands like Nissan and Honda models.

From my driving experience, CVT is definitely a part of automatic transmissions. After driving a CVT-equipped car for several years, I find it incredibly convenient in traffic jams or during long trips—there's no gear-shifting jerkiness, just control the accelerator pedal. The acceleration is as smooth as gliding, enhancing comfort, especially for daily commutes. In terms of fuel consumption, it indeed saves more compared to manual or traditional automatic transmissions, averaging an extra 50 kilometers per tank. Some models, like Toyota's hybrids, combine CVT with electric technology, further enhancing its automatic characteristics. Although occasional maintenance of the pulley system is needed, this doesn't affect its status as an automatic option.

In the classification of automotive transmissions, CVT is categorized as an automatic type. It achieves seamless acceleration by continuously adjusting the gear ratio without requiring manual intervention from the driver, operating fully automatically. Commonly found in economy cars, it improves fuel efficiency by approximately 8-12% and offers a quieter driving experience. However, unlike traditional AT transmissions, it lacks fixed gears. In use, it's as simple as pressing the accelerator to move forward, making it effortless and convenient. For maintenance, only regular transmission fluid changes are needed. Confirming this can help in selecting a vehicle that suits your needs.
