What is a CVT?
The gearbox is a very important element of every vehicle. Various types of such systems are installed in modern cars. Among them, it is worth mentioning, among others: CVT gearbox. What is it and how does it work? We give you a hint
- The CVT transmission is an automatic, continuously variable transmission,
- Its features include smooth gear changes, quiet operation and high driving comfort,
- The disadvantages of the CVT transmission include: lower driving dynamics and monotonous acceleration.

The CVT gearbox is one of many versions of an automatic gear shifting system. It provides driving comfort, but only works best for a specific driving style. First of all, the CVT transmission is known for its smooth ride. What does this mean? First of all, the smooth gear change.
What is a CVT transmission?
Primarily skrzynia CVT is a continuously variable automatic transmission. It does not have a specific number of gears. Thanks to it, gear ratios are changed steplessly and smoothly, without the driver's intervention. This type of gearbox allows you to select the appropriate RPM range for specific driving parameters.
A characteristic element of the CVT mechanical gearbox is a steel belt or chain. This is the most important difference between this component and other transmission models used in modern cars.
Construction of the CVT gearbox
Automatic continuously variable transmission there are no classic gears. Instead, a steel belt or chain is used. These elements move between bevel wheels, which slide on shafts. Such action is possible using electronic systems. Importantly, the CVT gearbox does not have a clutch.
When you accelerate, Automatic Transmission CVT increases the diameter of the input gear and decreases the output gear. This allows the car to go faster at the same RPM.
How to change gears in a CVT?
How to drive a car with a continuously variable transmission? The ride itself is not difficult. It is crucial to know how the CVT transmission works. In fact, the gear changing itself is performed similarly to other types of automatic transmissions. What should you remember when using a continuously variable transmission? First of all, about the position in which the jack should be set. How to use automatic driving modes?
- Position D – driving forward,
- R position – reverse gear,
- position N – this idle or so-called looseness,
- Position P – means standstill mode.
Advantages of the CVT gearbox
It is worth remembering that CVT automatic transmission has many advantages. The most important of them are:
- low fuel consumption when you do not accelerate rapidly;
- quiet operation, which affects your comfort while driving;
- high driving smoothness, also uphill.
First of all, CVT is an automatic system, so it does not require the driver to maneuver the stick himself. This makes it extremely convenient to use, especially for people who do not have much experience in driving.

Disadvantages of the CVT gearbox
Every system also has disadvantages - even the CVT transmission. What are we talking about? Opinions of users of cars with a CVT gearbox most often concern loud and monotonous operation during sudden acceleration, as well as worse dynamics compared to classic automatic models.
A continuously variable transmission may also result in higher fuel consumption in dynamic, variable driving styles. Therefore, it will not work for people who tend to accelerate and brake suddenly.
What is important, CVT transmission however, it may wear out faster than other systems. It is destroyed especially when you drive fast, dynamically and with high torque. This type of gearbox works best for monotonous, relatively slow driving without sudden braking and acceleration.
Where is a CVT gearbox most often used?
Infinitely CVT automatic transmission it is used primarily in front-wheel drive cars. It works well in light and compact cars, ideal for city driving, with low torque. This is a good choice for people who do not like manual gearboxes. The CVT variant is more expensive, but provides much greater driving comfort and allows you to fully focus on the road.
When to choose a car with a CVT gearbox?
Car with CVT gearbox will be a great choice for you if you drive calmly and avoid sudden changes in speed. You will also definitely like lower transmission service costs and lower fuel consumption. When is it better to reject the option of a continuously variable transmission? First of all, when you want the emotions of dynamic driving and you like the roar of the engine.
Cars with CVT gearbox
Continuously variable transmissions are a popular type of transmission. In which cars can they be found? Cars from CVT transmission These are primarily vehicles manufactured under the Lexus, Nissan, Toyota, Volvo, Renault, Opel and Audi brands. These are brands often found on Polish roads, so it is not difficult to spot such cars on the street.
What is the difference between a CVT and a classic automatic transmission?
Although CVT continuously variable transmission seems to be identical to classic automatic and DSG gearboxes, there are some differences. This is primarily lower service and fuel costs. At the same time, the driving is not very dynamic. In addition, there is a monotonous engine noise, which many people may not like.
e-CVT gearbox
There are also e-CVT gearboxes, which are most often used in hybrid cars. However, they do not have chains and belts. Instead, there is a planetary gear in such a box. It works with the generator and the car's electric engine.
The e-CVT also has the ability to recover some energy during braking. In this way, it is possible to reduce fuel consumption, which translates into vehicle operating costs. E-CVT gearboxes are also generally more durable than classic CVT models.
We hope you found our article about continuously variable automatic transmissions interesting. CVT gearboxes guarantee comfortable driving thanks to smooth gear changes. Mainly because the gearbox itself selects the gear. It is also worth remembering that in addition to vehicles with a CVT transmission, there are also hybrid cars with an e-CVT transmission.
