What is a CVT (Continuously Variable Transmission)?

The most common types of transmissions are automatic and manual. But there is a third type of transmission called Continuously Variable Transmission also known as CVT. The term “continuously variable” means seamlessly changing through an unending range of effective gear ratios while you drive. Other mechanical transmissions only offer a fixed amount of gear ratios and they have hard shifts in between each gear. CVTs have been around since the latter part of the 1980s but are becoming more common than ever due to the better fuel economy compared to the other kinds of transmissions. Not only does CVT transmission provide better fuel economy but also power usage is better due to how CVT allows the engine to function at optimum power. 

Different Types of CVTs (Continuously Variable Transmissions)

Hydrostatic Continuously Variable Transmission: A type of CVT that uses a hydraulic motor and a variable displacement pump. The pump regulates fluid flow which in return creates a rotational motion.

Toroidal Continuously Variable Transmission: A type of CVT that executes smooth continuous gear ratio changes using rotating discs and power rollers between the input disk and output disk. 

Pulley-Based Continuously Variable Transmission:  The most common type of CVT uses a V-belt. This V-Belt runs between two variable-diameter pulleys. Instead of gears, Pulley-Based CVT uses an intricate pulley system to provide seamless gear transitions.

CVT – Pros and Cons: 

Pros: CVTs offer a faster and more responsive acceleration by matching the torque output with the correct gear every time. CVTs will always select the highest gear and remain there to save fuel. CVTs do not have to hunt for gears when climbing hills. CVTs have none of the jerkiness of a standard automobile. It operates smoothly. CVTs are lighter and smaller than the automatic transmission, and in return reduce the weight and save on fuel.

Cons: CVTs are less engaging. CVTs make loud noises during hard acceleration. Some people say it has a rubber band feeling when they step on the pedal. They may not last as long as other transmission
