What Does CVT Stand For?
Autotrader explains the term CVT stands for continuously variable transmission.

Advantages of CVT
Depending on the vehicle and the driver, a CVT can provide a smoother driving experience when compared to a traditional automatic.

According to Carfax, one of the most significant advantages to having a CVT is that they are often more fuel-efficient than a regular automatic. This is part of the reason why they are becoming a more popular choice for automakers in many vehicles.

How Does a CVT Work?
In order to see how a CVT works, How Stuff Works explains, you need to understand a manual and a traditional automatic. A manual has a set number of gears, and the driver determines what gear ratio they need. An automatic also has a set number of gears, but it uses a hydraulic system that responds to pressure created by the conditions to determine the gear needed without any input from the driver.

A CVT is similar to an automatic in that it doesn't use any input from the driver, but that is where the similarities end. A CVT doesn't have any gears. Instead, it has two pulleys. One pulley connects to the engine, and the other connects to the wheels. A flexible belt connects the two pulleys

The width of the pulleys changes depending on how much power the vehicle needs. When one pulley gets larger, the other one gets smaller. Since neither the pulleys nor the belt are fixed, they can provide an infinite number of gear ratios, unlike the automatic, which has a set number of gears.

Not all CVTs are created the same. The most common type is the pulley-based, but some other types include the Toroidal CVT, which uses rotating discs along with power rollers to produce the same result as the pulleys. The hydrostatic CVT uses pumps to control fluid flow, which then produces a rotational motion.

What Is Launch Gear?
Toyota recently made some changes to its CVT. CNET says it now uses what they call a Launch gear to provide drivers with the feeling of a conventional transmission. The launch gear is almost like the first gear in a regular automatic transmission. As the vehicle speeds up, the transmission will switch this out, so it starts working as a CVT. Toyota says that using these new fixed gear ratios will not only feel more like a regular transmission; It will also increase belt efficiency and improve performance.

Which Is Better Between CVT and Automatic Transmission?
One of the advantages of a CVT is its ability to continuously change its gear ratio. This means that no matter what the engine speed is, it always performs at its peak efficiency. CVTs often offer better fuel economy as a result, especially when driving in the city.

Digital Trends says that most cars equipped with CVTs offer a smoother ride than a similar car with a regular automatic. This is because the transmission never shifts. There is no abrupt downshifting when the car needs additional power, and there is no feeling of gear hunting that you sometimes feel with a traditional automatic.

A CVT is lighter than a traditional automatic, and this, combined with the smoother operation, helps to improve the fuel efficiency of vehicles that come equipped with a CVT.

Because of the lack of gearing, it is easier for CVT vehicles to find and maintain an ideal torque ratio as well. It has an easier time taking off from a stoplight and an easier time climbing difficult terrain because the variable transmission allows it to run in the right "gear" and stay there.
