CVT vs 6AT： Comparison of Advantages and Disadvantages in the Eyes of Old Drivers

With the continuous development of automobile technology, automatic gearbox has become the standard of modern automobile. CVT (continuously variable transmission) and 6AT (six-speed automatic transmission) are the most common types of automatic transmission. So, what is the difference between these two gearboxes? Which one is more suitable for your needs? This paper will make a detailed comparison from many aspects, and combine the professional opinions of the maintenance master to help you make a wise choice.

continuously variable transmissionCVT gearbox realizes stepless speed change through the combination of steel belt and pulley, which can provide smooth power output at different speeds. Its biggest feature is that there is no fixed gear and the speed change process is very smooth..

6AT gearbox6AT gearbox adopts hydraulic torque converter and planetary gear set, and realizes speed change through six fixed gears. Each gear has a specific gear ratio, which can provide corresponding power output at different speeds..

continuously variable transmissionBecause there is no fixed gear, CVT gearbox has high transmission efficiency and can make better use of the engine power, especially in urban driving..

6AT gearboxThe transmission efficiency of 6AT gearbox is slightly lower than CVT, but its mechanical transmission structure can bear more torque, which is suitable for high-speed driving and heavy load..

continuously variable transmissionCVT gearbox is excellent in fuel economy, which can automatically adjust the speed ratio according to driving conditions and reduce fuel consumption..

6AT gearboxAlthough the fuel economy of 6AT gearbox is not as good as that of CVT, its fuel efficiency has been significantly improved with the progress of technology..

continuously variable transmissionThe smoothness of CVT gearbox is very good, and there is almost no sense of shifting, which is suitable for users who pursue a comfortable driving experience..

6AT gearbox6AT gearbox may have a slight sense of frustration when shifting gears, but its shifting speed is fast, which can provide a more flexible driving experience and is suitable for users who like sports driving..

continuously variable transmissionThe structure of CVT gearbox is relatively simple, but it requires high maintenance, especially the maintenance of steel belt. Changing the transmission oil regularly can prolong its service life..

6AT gearboxThe structure of 6AT gearbox is complex, but its technology is very mature, with low failure rate and relatively low maintenance cost..

As can be seen from the above comparison, CVT and 6AT gearboxes have their own advantages and disadvantages. CVT gearbox is suitable for users who pursue smooth driving and fuel economy, while 6AT gearbox is suitable for users who pursue power and driving pleasure. When choosing, it is recommended to choose according to personal needs and driving habits.
