No, a continuously variable transmission (CVT) is not an automatic transmission in the traditional sense.
Variable speed transmission (CVT)
A CVT is a type of continuously variable transmission that uses two conical discs connected by a belt or chain. The discs can move closer together or further away to smoothly change the gear ratio. This provides an infinite range of gears between two extremes, eliminating the need for fixed gears.
Automatic transmission
A traditional automatic transmission (AT) has several fixed gears that it shifts between depending on vehicle speed and load. Automatic transmissions usually have from 4 to 8 gears, and switching between them occurs in steps, which leads to noticeable jerks.
Key Differences
* Smooth shifting: CVT provides smooth shifting while automatic transmission shifts in steps.
*Continuously Variable: CVT has an infinite range of gears, while an automatic transmission has a limited number of fixed gears.
* Efficiency: A CVT can be more efficient than an automatic transmission because it can operate at the optimal gear ratio for any driving condition.
* Repairs: CVTs tend to be more difficult and expensive to repair than automatic transmissions.
* Driving Feel: The CVT can create an unusual driving feel as the engine speed does not necessarily match the vehicle speed.
Conclusion
Although CVTs are sometimes called “automatic transmissions,” they differ from traditional automatic transmissions in their design and operating principle. CVTs provide smooth shifting and high efficiency, but can be more difficult to maintain and less enjoyable to drive for some people.
